Van Alstine Transcendence 10 RB Preamplifier ($900)

AVA Transcendence 10 RB Preamplifier.jpg
AVA Transcendence 10 RB Preamplifier.jpg (58.82 KiB) Vist 3310 gange

The Transcendence 10 RB is an all-tube preamplifer that will appeal to audio purists embracing minimal setups and anyone looking for affordably priced, astonishingly detailed and musical tube sound.

The audio circuits are an improvement of our award winning Transcendence 8 tube design. In addition, we have recently completed extensive testing and refinement of our already class leading layout practices and employed those findings into the Transcendence 10 RB design. This engineering has resulted in the lowest noise tube preamplifier we have ever offered. The Transcendence 10 RB is an astonishingly natural, engaging, dynamic, high-resolution preamplifier that can interface seamlessly into and improve the most demanding audio systems.

The T10 RB is shipped with 2 premium select 6DJ8 tubes. 6CG7 or 6N1P tubes can also be used. Only the highest quality parts are used. We use 1% precision metal film resistors and all capacitors in the signal path are select polypropylene types.

AVA has long been an advocate of rock solid power supplies, and the power supply used in the T10 RB is no exception. The high voltage supplies are based around an RC PI network driving four active high voltage regulators, one for each tube section. This design takes supply noise and interaction down to nearly zero. In addition, there are separate regulated power supplies for the tube heaters and the headphone amplifier. The main circuit board uses multiple isolated ground planes strategically interconnected to eliminate the effects of ground currents. A very quiet custom made shielded power transformer completes the power supply design.

The Transcendence 10 RB also includes an exquisite headphone amplifier capable of driving the most demanding headphone loads. All Audio by Van Alstine amplifier have outstanding headphone performance. In our vacuum tube preamplifiers the headphone drivers are simply current buffers to provide a high current and low output impedance to any headphones. The active current amplifier for each channel is an LME49600 which has a 2000V/µS slew rate and all of 0.00003 percent THD. So with AVA tube preamps, what you are actually listening to is the line tube section with only that ultra distortion buffer afterwards.  No gain stages or transistors used at all.

Our goal with the RB chassis design was to eliminate functions that audio purists don't use. This significantly reduces the parts and labor costs without compromising the audio quality. It allows us to offer uncompromising sonic beauty at a much lower cost than you would ever expect. The RB Chassis has a precision volume control, four sets of line level inputs (with one input being used for the optional phono section, if specified) and two sets of line audio outputs. The aluminum faceplate is finished with our incredibly durable double-anodized process. All input and output jacks are gold plated, and a removable IEC power cord is provided. Dimensions: 17" wide x 12" deep x 3.5" high. Shipping weight is 17 pounds.

Fezz Omega Lupi ($1050)

Fezz Audio Omega Lupi.jpg
Fezz Audio Omega Lupi.jpg (1010.54 KiB) Vist 2971 gange

An amplifier that can handle even the most demanding headphones. The natural and artistic presentation, as offered by the Omega Lupi, leaves no doubts that this is a highest class device.
Check what Your headphones are really capable of. From now on Your amplifier will not be a limiting factor.

Omega Lupi, is the design that we worked on the longest in our history. We opened the project in March 2017 and presented the prototype in November of the same year during the Audio Video Show in Warsaw. We wanted the opinions of the users and even though they were positive, we knew then that the design would satisfy us only when Omega Lupi was able to drive even the most demanding headphones - also those with extremely high impedance.

We knew thera were a lot of headphone amplifiers on the market, but either they were simple designs for relatively cheap headphones, or very expensive ones, for extremely demanding customers, and we wanted to create a universal headphone amplifier for a wider group of people listening to music in this way.

That is why, right after the Show ended, we started work from the very beginning. The chassis was the only element left from the prototype. Everything inside was rebuilt from scratch. As you well know, the heart of each tube amplifier are not only the tubes but, above all, transformers, and we spent the most time building those. But it's probably obvious - Toroidy.pl is a strong player on the market of audio transformers and we have unique experience with different types of designs.

Omega Lupi is a one-of-a-kind amplifier. Most of the headphone amplifiers are OTLs - that is, featuring no output transformers. And we wanted the headphones to be treated in our design as a loudspeaker set, because what other than good loudspeakers headphones are? The only way to achieve this is to match their impedance using transformers - in other words, do it in the same way as in an integrated stereo tube amplifier.

We have therefore designed winding in our transformers to optimally match headphones with low (up to 32 Ω), medium (up to 300 Ω) and high (up to 600 Ω) impedance. Thanks to this solution we have achieved optimal working conditions of headphone drivers, and thus negligible low distortion and great dynamics while maintaining the tube character of the sound.

Omega Lupi is a very efficient amplifier. During the designing process, we examined about 30 pairs of headphones - starting from the simplest dynamic ones, through several hundredth ohm ones used often in studios, and ending with planar Audeze models. Each and every time our amplifier had enough “juice” to properly drive every cans.

At this point, an important question comes to mind: why PCL86? One of the reasons is historical - we built our first tube amplifier called Laura (still as Toroidy.pl) using this tube, which captivated many listeners. The second reason is - we value this tube very much. Considering its price, availability, sound and origin (POLAMP Nakło), we could not deny ourselves the pleasure of designing an amplifier using the PCL86 valve.

This is an outstandingly engineered design, technologically advanced (two tubes in one glass enclosure) triode-pentode. It's a pity that nobody is producing them today. Fortunately, due to the wide availability of NOS tubes (these were, after all, very popular TV tubes), they are easy to buy and at very low prices. Fezz Audio bases on the NOS tubes made by the Polish company Polamp, which are still available on the market and we believe that someday they will come back to the market.

We would like to draw your attention to the restrictive selection of tubes and the exceptional care of assembly. It is about exceptionally demanding sound aspects - after all, according to the design assumptions, it is an over-ear speaker system. So we put the ear in the speakers and there must be an absolute silence, black background, no hum - just silence.

Re: Rør, hvis du tør - OCTAVE Audio

OCTAVE V16 Single Ended (€8500)

OCTAVE V16 Single Ended.jpg
OCTAVE V16 Single Ended.jpg (301.83 KiB) Vist 3532 gange

The new OCTAVE V 16 Single-Ended amplifier:
Uncompromising Single-Ended Class-A technology, redefined.

The founding principle at OCTAVE has always been to apply modern innovations to classic tube technology. The time has now come for OCTAVE to apply the company's exclusive amplifier technologies to a single-ended design, as this circuitry is desirable for its natural audio reproduction and is capable of realizing clear sonic benefits that are particularly ideal for high-efficiency loudspeakers as well as for headphones. Single-ended amplifiers possess a naturally harmonic sonic signature and offer an extremely lucid midrange, as the music signal is not split and thus no crossover distortions of the positive and negative half-waves arise.

Developing a single-ended Class A circuitry presented a unique challenge for OCTAVE: how to fully overcome the disadvantages of this amplifier principle while bringing its sonic benefits to the forefront. OCTAVE applied its myriad technical innovations and proprietary output transformer technology to develop a sophisticated new amplifier to meet this challenge: The result is the all-new OCTAVE V 16 Single Ended integrated amplifier, the company's first ever single-ended design.


While the natural sonic character and midrange clarity of the single-ended circuit is uniquely desirable, there are also some known limitations to the single-ended amplifier topology that needed to be addressed:

1. Level reduction in the bass frequencies – OCTAVE has eliminated this problem inherent in single-ended amplifiers via a new, highly specialized magnetic-field compensated output transformer. OCTAVE is renowned for its proprietary transformer designs which are developed, wound and meticulously crafted in-house. The power bandwidth in the bass frequencies of the OCTAVE V 16 Single Ended remains linear up to 10 Hz as a result of this customized transformer design.

2. Level reduction in the high frequency range and limited bandwidth - By means of specific driver stages and an optimization of the feedback, OCTAVE has been able to extend the bandwidth of the OCTAVE V 16 Single Ended from 10 Hz to 100 kHz, a bandwidth spec that was previously considered impossible to achieve from a single-ended amplifier design.

3. Relatively high residual noise in the loudspeaker output - The level of hum in the OCTAVE V 16 Single Ended was rendered virtually immeasurable via OCTAVE's optimized positioning of the mains transformer in respect to the output transformer, which also negates the need for an outboard power supply. The company's sophisticated electronic stabilization circuits serve to further ensure that any sources of noise or hum is eliminated. The low-frequency noise level achieved at the loudspeaker as well as the headphone outputs is in the range of – 110 dB / 1W at 8 ohms, which corresponds to approximately 15 – 20 μV at 50 Hz.

4. High temperatures during high-current rest in Class-A operation – Most single-ended Class-A amplifier designs are extremely inefficient, typically idling between three to five times the output power. Thus these devices become very hot during normal operation. The OCTAVE V 16 Single Ended single-ended amplifier utilizes an adaptive three-step setting of the Class A mode. The Class A Level is automatically adjusted between 100% and 35% to the load profile of the loudspeaker (4/8 hms) and headphones, which considerably reduces the amplifier's operating temperature, while significantly extending its lifespan as well. In addition, the OCTAVE V 16 Single Ended features a unique version of OCTAVE's energy-saving "Ecomode" technology, which serves to reduce the Class-A level to 35% during pauses in the music signal, and inaudibly rises when a musical signal is once again present.

5. Disadvantages of expensive, directly heated triodes - OCTAVE has developed the OCTAVE V 16 Single Ended to operate a KT 120 pentode tube in a triode circuit. It is ideally suited for Single Ended Class A operation due to its particular characteristics: very high performance, excellent longevity, tight tolerances, and widespread availability – while avoiding the technical problems of a traditional triode tube such as the 300 B. The OCTAVE OCTAVE V 16 Single Ended architecture will thus also allow the use of KT 150, KT 88, or 6550 tubes, for example, making its design extremely universal.


OCTAVE has also equipped the V16 Single Ended with an optional Pre-Out feature (needs to be opted for at time of purchase, cannot be installed later). While adding complexity, this option affords great flexibility. Thus the V 16 Single Ended is a perfect companion to myriad system setups, and can be used to drive headphones, high efficiency loudspeakers, hybrid systems (with active bass), or in conventional bi-amp setups. An equalizer is used to cut the deep bass frequencies (below 80 Hz), so the V 16 Single Ended is only responsible for the midrange and treble. The frequency range is optimized by Octave and thus not adjustable. One primary benefit in the case of bi-amping is to take advantage of the breathtakingly beautiful single ended performance in the sensitive mid and high frequency range while employing a separate power amp (or internal amp in the speaker) to handle the bass region.


The long development time of the OCTAVE OCTAVE V 16 Single Ended has surely paid off: an uncompromising single-ended Class A integrated amplifier that delivers ultra-quiet operation highlighted by deep bass, a natural midrange and silky-smooth highs combined with an unsurpassed degree of reliability and longevity. A pure, modern classic amplifier in every regard.

Euforia's unique design allows for exceptional sound quality with a broad range of headphones, powerful enough to drive even demanding low impedance headphones (<32 ohm) including planar magnetics.

In the 2018 model a user-switchable Cross-Feed function enables more natural channel balance and wider soundstage. Input/output safeguards eliminates undesirable power on/off noises and distortions. Pre-amp safe mode has been implemented as well. And driver tubes have been upgraded to highest quality PsVane CV181-TII “Gold”.

Euforia is originally equipped with high quality tubes. They can be changed by the user, to the following:
Driver tubes: 6N8S, CV181, ECC32, 5692, 6F8G
Power tubes:6080, 5998, 6N5P, 6N5S, ECC230, 7236, CV2523

Power supply is based on a custom made stabilized toroidal transformer with electronic ripple suppression. The amplifier is equipped with automatic bias circuit, therefore no re-tuning is required after changing tubes.

Electron Audio IMP (€500)

Electron Audio IMP.jpg
Electron Audio IMP.jpg (279.59 KiB) Vist 9879 gange

IMP is a tube OTL (Output TransformerLess) amplifiers based on our proprietary MT-OTL technology. The IMP amplifier is intended for 32 ohms and above impedance headphones.

• Output power: min. 130mW (into 32 ohms)
• Compatibility: min. 65mA RMS into 16-600 ohms
• Tubes, per channel: 6J6 (driver stage), 7AK7 (output stage)

• MT-OTL technology – a result of our own research and development, MT standing for ‘Mirror Triode’. It uses a hybrid element to provide a push-pull output configuration where an output triode is opposed to it’s own mirror image. However, unlike the classic push-pull, a triode and ‘anti triode’ opposed do not result in a combined element that suppresses even harmonics (an acceptable but not the most desirable characteristic of the classic push-pull topology), rather, it results in a ‘double size’ triode. The end result is that of two parallel triodes in a SE (Single Ended) topology, retaining the natural distribution of harmonics that is one of the defining characteristics of SE. At the same time, the MT circuit insures proper operating conditions of the output triode in strict class A. The whole circuit does not require any adjustment nor matching tubes – and offers a significant reduction in power consumption and heat generation, to boot. The usable bandwidth of an MT-OTL amplifier easily exceeds that of any currently standard HD audio formats.

• Lifetime Warantly on output tubes – OTL amplifiers as a rule get labeled as ‘tube eaters’. Because of this we have chosen high reliability pentode tubes with multiple control options, which offer a multitude of possible configurations. Out of these, we chose a high linearity triode connection, which exceeds even the linearity of the legendary 300B tube, and also happens to be the most suitable for OTL operation. These tubes were made for the military and navy, and are specified for at least 10000 operating hours in the harshest conditions. Because of this, they found use in transoceanic telecommunication cable repeaters, where tubes are documented to have logged more than 100000 operating hours. We operate them very conservatively so they will last a lifetime.

• Two inputs with link function to other components – in case the amplifier is integrated into a larger system that shares sources, we provides two inputs and through (‘link’) connections to another amplifier. In this manner it is possible to use the headphone amplifier without having to switch on the rest of your system.

• Careful filtering and regulation of the power supply – even mediocre headphones will reproduce signals on the order of microvolts, while SE topologies (effectively the mode of operation of an MT-OTL amplifier) generally do not offer high levels of suppression of power supply noise and hum. This situation requres special effort to insure a high quality, stable and quiet power supply of the amplifier circuits. Both amplifiers feature multiple filtering, regulation using a low noise voltage reference and post-filtering of the power supply, for a stable power supply impedance and output voltage.

• The IMP amplifier only offers dual post-filtering, which is still several steps ahead of many competing products.

The resulting two mono amplifiers are connected together in a single point, the star ground of the input and phones connectors.

ENIGMAcoustics Athena A1.jpg (275.56 KiB) Vist 9879 gange

Single-Ended Triode Vacuum Tube Hybrid Headphone Amplifier

The Athena A1 is an audiophile’s dream. From its three dimensional soundstage to its ability to faithfully articulate voices and instruments, to separate and fix them in space, the Athena A1 is an engaging and musical headphone amplifier.

Designed by a virtuoso engineering team, it is the first headphone amplifier from ENIGMAcoustics. It is also represents the culmination of an exhaustive design effort, hundreds of hours of listening, miles of response curves, and carefully selected parts.

Driven in pure Class-A mode, the premium grade Genalex Gold Lion ECC82/B749 tubes – chosen for their sonic purity and low noise – provides the foundation for Athena A1’s single-ended front end. A full wave rectifier is followed by LC smoothing filter with huge and powerful audio grade capacitor. The Class-A MOS/BJT hybrid output stage is extremely solid and robust (only the renowned BJT is considered) and it is a great complement to the single-ended triode front end. Together, they render music that flourishes with all the harmonic hues of live music.

The output stage exhibits extremely low output impedance, which ensures compatibility with low impedance headphones; and its high output voltage swing also allows Athena A1 to effortlessly drive high impedance headphones as well.

Elegantly presented, the Athena A1 features a strikingly attractive visual design, glass exterior, and state of the art construction. This innovative and bewitchingly musical vacuum tube headphone amplifier may well have re-written the book on SET (Single-Ended Triode) design.


Specifications
• Input Impedance: 10k Ohms
• Maximum Output Voltage: 20Vpp
• Total Power Consumption: 15W
• Compatible Headphone Impedance Range: 16–600 Ohms

Dragon Inspire IHA-1 ($1700)

Dragon Inspire IHA-1.jpg
Dragon Inspire IHA-1.jpg (57.75 KiB) Vist 9879 gange

Moon Audio is proud to host and share the return of the legendary Dennis Had, to the world of tube headphone audio. This IHA-1 Dragon Version, stereo vacuum tube headphone amplifier maintains Dennis' philosophy reinforced over decades of listening, designing and building audio amplification.
As with Dennis' previous designs, his main concern is always the sonic purity of the output signal as perceived by the human ear. The IHA-1 Dragon is vacuum tube amplification in its purest form. The Dragon IHA-1 utilizes a100K dual DACT stepped attenuator. No matter where one has the volume set the balance is equal at all times in each channel. The Amp has Pro-Audio outputs on the front panel. You will notice the locking 1/4" stereo output. In addition we have chosen to have the XLR 4 pin balanced output connector. The IHA-1 is a single-ended design but as you know it delivers the output in a balanced form from the output windings from the air-gaped output transformers. Then a final touch is a dual process powder coat finish in a clear coated copper.

The input driving signal is directly coupled to the grids of the 6SN7 dual triodes. This signal is amplified and sent to the headphones through a set of special hand wound air gapped output transformers. Once again, direct coupling straight through to the headphones. Utilizing the 6SN7 dual triodes, the IHA-1 is extremely linear and offers full bandwidth from 9 Hz to 33 Khz without the use of feedback.

The power supply is vacuum tube rectification with dual filter chokes to provide a low noise level along with a low impedance B+ power supply to the 6SN7 tubes. All and all, he had little concern for how loud one could blast their ears but an ongoing concentration of full bandwidth, linearity and a realistic music presentation. Once again, for fear of being repetitive, the new Inspire IHA-1 Dragon version, is vacuum tube amplification in the purest form.

For tube rolling, the rectifier tubes should be of the direct heater type like the 5Y3, 5U4, 274B or NOS and factory fresh direct heated filament types. The indirect filament type like a 5AR4 are fine to use but to his ear they do not even come close to a directly heated filament type.

The output tubes can be of course, 6SN7, 6BL7 and Dennis's favorite with less gain are the 6BX7 which are plenty loud for Drew's taste as well.

The THD is close to ultimate vacuum tube perfection considering zero feedback. The second and all remaining harmonic contents at the 1.125 watt output level into 32 ohms are over 65 dB down. Actually the only harmonics visible at these levels are the second harmonics down 65 dB and the other harmonics are in the noise floor. This is actually an amazing output spectrum. One would consider this for the board of health!!! LOL The power levels vary with the impedance of the output load. At the 32 ohm level up through 570 ohms the power is in the 1.125 watt to .750 watt level. Higher power at the lower end of the range. It will drive the 600 ohm cans you have as one of your choices.

Please keep in mind this is a direct coupled design without any coupling caps or output attenuation resistors in the signal path. Purity at its best.

This Exclusive Dragon version includes:
• a Gorgeous Copper Metallic Powder Clear Coat finish
• a Stepped DACT 100K attenuator running a pair of 6SN7's at over 1 watt of output power
• Output impedence of 4.4 ohms
• Transformer Pro Balanced output
• 2 analog RCA input selector positions, including a mute position

• direct coupling and transformer output are included as part of the standard configuration.
• 10 inches wide 8 inches deep, height varies based on tubes used.
• Weight is 15lbs

Reußenzehn Harmonie III - MasterClass.jpg (173.82 KiB) Vist 9879 gange

The Reußenzehn MasterClass constitutes a development of more than 20 years of successful and popular tube headphone systems. The performance is nearly tripled with 2 x 3.5 W compared to the older models, thus the dynamic range and headroom has been increased substantially. The MasterClass allows you to connect all available dynamic headphones on the market with an impedance of 16-600 ohms.

The sound is warm and transparent, yet extremely spatial and powerfull across the whole frequency range. The amplifier has separate volume / voicing control for each channel (4 controllers). The voicing knob controls the harmonic overtone spectrum of the electron tubes (neutral position at 12 clock). Increased second harmonic overtone allows for perceived increased brilliance, airiness and spaciousness

Dimensions are 20 x 12 x 10 cm. MasterClass is available in black (€1280), chrome (€1480) or gold plated (€2200). XLR tonnectors are now standard. The power supply is housed externally for reasons of quality.

Optional: MasterClass Duo Comfort (€190). The Duo Comfort extension is a double-connection box for 1 or 2 headphones to the Reußenzehn MasterClass headphone amplifier. A high-quality cable is made-up for the customer in the desired length. The MasterClass headphone amplifier can thus remain in the HiFi rack, and the extension box can then be placed near the actual listening position. The technique allows listening pleasure without volume or quality loss up to 6m (9m with headphones) cable length.

Audeze The King MKII ($4500)

Audeze The King.jpg
Audeze The King.jpg (44.33 KiB) Vist 9879 gange

THE KING MKII Class-A Hybrid Tube/Mosfet Headphone Amplifier

The King was designed exclusively for Audeze by legendary circuit builder Bascom King. It’s a two-stage hybrid design featuring a pair of twin-triode E88CCs input tubes, a differential P-MOSFET driver, and MOSFET output devices. The King uses NPN MOSFETs that allow perfect device matching that yields faster response times. The amplifier exhibits low impedance, low distortion, and wide frequency response along with its 6W of music power, characteristics that create a breathtakingly spacious and emotional listening experience.

The King’s anodized casework is beautifully done and solid as a vault. The side panels are fully 1/2" thick, the top and bottom 1/4" thick, featuring a 5/8" thick clear-coated front panel. All active components are "faraday cage" shielded along with the AC input to reduce RFI. The front-panel meters are engineered to reflect actual SPLs and power levels when used with the LCD-4.

Bascom King’s exclusive design for Audeze includes such perfectionist elements as left and right channels on separate PCBs, each with its own voltage regulators. Each PCB features a protective shield of perforated, powder-coated magnetic material. The toroidal transformer is massively oversized, molded in epoxy and shielded to further improve signal-to-noise ratio. A DC servo circuit between input and output stages keeps DC offset as close to zero as possible. And a symmetrical regulated power supply delivers ±16V DC to the output devices and there are no capacitors in the signal path resulting in virtually flat frequency response.

Gabri’s VEGA-X (€1490)

Gabris Vega-X.jpeg (573.59 KiB) Vist 4181 gange

The VEGA-X is a new model that we developed to offer a complete and versatile solution to all the fans who have always dreamed of an amplifier made entirely in Italy, with a simple but elegant design and tranquility guaranteed by 5 years official warranty.
 
REMOTE CONTROL: Developing this project we wanted to give you the convenience of being able to handle everything from dedicated remote control, in addition to the classic function of the motor-driven volume that most manufacturers offers, we have implemented (developing our own remote control kit) input select, mute and standby functions, all controlled by the included remote control.
 
INPUTS: The integrated turntable input is a real treat for lovers of analog music and vinyl. Usually integrated tube amplifiers, given the complexity of positioning and the abundance of components that can affect and interfere with the signal, have no such input, and it is often possible to add an external pre-phono modle that in 90% of cases is solid-state, paying extra. The VEGA-X offers an internal module already installed as standard, with two dedicated valves 6N2P-EV (nos military "low noise" version) and therefore the usual corrector RIAA in feedback. In addition to the PHONO input "MM" there are 3 line inputs that accommodate the classic known sources (CD player, DAC, TV, Streamer etc..).
 
BIAS: all owners of tube amplifiers know the necessity of the regular power tube BIAS adjustment to ensure the system performance always at the top. In this case you won't have any kind of concern because the system of AUTOMATIC BIAS, not only makes the valves during operation but also allows the replacement of the power tubes without the need for adjustments techniques.
 
OUTPUTS: In addition to the indispensable power output with variable impedance (4-8 ohm), you have a universal headphone output on the front that allows you to enjoy the quality of the tube sound even through headphones during moments of extreme silence; There is also an RCA to record the sound of the selected input to an analog or digital device.
