Clinamen Ariel (€3450)

Clinamen Ariel .jpg (140.38 KiB) Vist 57513 gange

The amplifier is completely single ended, with two active stages made with high-performance valves: the 6H30 that serves as a stage driver is used in a configuration that maximizes the linearity and the voltage swing; the power valve, for audio use, EL84, triode connected, provides 1 watt rms low distortion power.

The peculiarity of this circuit, compared to the majority of Headphone amplifiers, is that it doesn't use output circuits OTL (output transformer less) for both safety and musical reasons: Clinamen indeed strongly believes that the way of impedance matching (a horn if we speak of acoustic impedances, an audio transformer if we speak of electric impedances) is the main way that allows to pursue the natural way of the sound.

Few components, inherently linear, carefully tied by the laws of physics, provide a dynamic and engaging sound, devoid of harshness and with a great emotional content. All active stages have fixed bias polarization, the driver has stabilised power supply with gas diodes. The power supply uses a generous filter inductance to provide a DC voltage with very low AC residue.

The wiring is entirely point-to-point with a very sophisticated mass system, in order to make inaudible any noise that would be extremely annoying in the headphones. The volume controls are independent for the two channels. Finally, the real power of 1 watt rms on load , it is absolutely superabundant to any sensible use of the device

The frame is in solid padouck, with a copper top plate, and a birch plywood bottom plate. The control panels are laser cut and gold engraved glass. Moving parts are made on an inhouse CNC machine.

Clinamen SATYA : E55L Single Valve (€5990)

Clinamen SATYA.jpg
Clinamen SATYA.jpg (1.37 MiB) Vist 47686 gange

SATYA is the ultimate Clinamen headphone amplifier, with the potential to become end game. It has a simple but extreme circuit design, and is built around a single valve --> the E55L.

This is a pentode with Magnoval base, a professional valve with a guaranteed life of 10,000 hours. It has fabulous electrical parameters (30 times gain with an internal resistance of only 650 ohms at the chosen working point) among which the transconductance of 45mA / V stands out.. these are numbers light-years ahead of those normally found in the High-end segment. Obviously we use it triode strapped obtaining the useful power of 0,8 Watt rms with distortion under 1% WITHOUT ANY FORM OF FEEDBACK.

The E55L in our working point it is exploited to 60% of its anodic dissipation and therefore the life of the valve is the last of your problems. The chosen working point was aimed at favouring linearity, without unnecessarily stressing the valve: in fact, we have a power exceeding the half Watt, which we consider abundant for listening through headphones. Linearity of the triode-strapped E55L is extraordinary: already for anodic current values of 30 mA, the amplification coefficient remains constant at the value of 30 and the internal ressitence well below 1000 ohms. The high transconductance has another extreme and delightful effect: the super quietness of the active device, and this in a headphone amplifier is an absolutely decisive aspect.


The circuit is extremely simple and uses custom parts of the highest grade: an input transformer with a Vacoperm core acting as voltage shifter and decoupler, a 24-position stepped attenuator volume control, and a custom Clinamen output transformer also in Vacoperm. Obviously all without any form of feedback. The custom Clinamen output transformer has two secondary windings allowing the output impedance to be set to 32 ohm or 128 ohm, thus covering a wide spectrum of headphones. The user-operatable impedance selector also has a MUTE position.

On the front there are two millivoltmeters, which thanks to the internal calibration, show the mA reading of the polarization of each valve (quiescent current). We preferred their use to the classic milliammeters because the voltmeters are placed in parallel and therefore are not crossed by the signal current, resulting in a better sound and increased reliability. Besides being very scenic, they are also perfect indicators on the good functionality of the circuit, or on the state of efficiency of the output valves. The reading of these must be within the range between 40 and 50 mV.

The E55L filaments are continuously fed with two independent stabilized power supplies.

There are three available inputs, switchable from the front selector which, via a return rod, controls the Palazzo switch, close to the RCA connectors. This shortens the signal path and minimizes noise uptake.

The power supply is made exclusively with cork-dampened polypropylene capacitors, for maximum dynamics and responsiveness to the music signal, with no tonal coloration, and for reliability and lasting durability.

Rectifier tube is EZ81, and three chokes perfectly filter the anodic voltage. Wiring is point-to-point obviously, with OFC silvered and annealed copper, teflon insulation. Solders with tin WBT 4% Ag.

The frame is in anticorodal 3 mm painted Venus gray metallic with laser serigraphy. The Clinamen logo and the name SATYA are highlighted thanks to a numerical control process, and a backlight through an opal material that diffuses the light of two orange LEDs ( color chosen to resemble the color of the tube filaments). The instruments are backlit with blue LEDs.

Chazz II ($500)

DIYHiFiSupply Chazz II.jpg
DIYHiFiSupply Chazz II.jpg (76 KiB) Vist 53168 gange

You may remember the Chazz. It used EL34/KT88 and 6SN7 (earlier versions 6SL7) and output transformers. Eventually we sold out and it was right at the time when chassis and transformer parts costs were escalating; our attentions were diverted to reworking our whole lineup to work within the new economic realities.

The Chazz2 makes it own statement. You be the judge: OTL through film caps. MUCH much better clarity, finesse and speed as compared to electrolytics.


Features

• Anode vs cathode sound.. Dual Outputs on the front panel: One takes from the anode and the other from the cathode. The circuit is patented and allows this little trick. It allows you to experience the difference between anode and cathode sound. You can also drive with both (two headsets) at the same time.

• True balanced-mode.. We now have a pure copper served with teflon cable which allows true balanced-mode and includes the HD600-type connectors for plug-in operation. It is a worthwhile difference.
Simply put: hot/cold conductor takes signal from the anode and cathode of the tube. You can still select local feedback level but as one headphone set uses both outputs, only one headset can be driven at a time in balanced mode. It runs true balanced. Only the screen is connected to the phono plug body but signal is totally floating and never touches ground.

• Linestage.. Also we configured a set of phono cables with RCA ends so the Chazz2 can also be used a a very beefy (and quiet) linestage to drive your big system. And still allows switching between anode/cathode feed and 0/3/6dB feedback. FUN! Allows voicing your hifi system.

• Adjustable feedback.. Front panel selector toggles 0/-3/-6dB feedback. A comparison is VERY interesting! You choose the flavour you like.

• Carbon attenuator because we don't like plastic in between us and the music. We are a carbon-based lifeform.

• Good for money tubes.. 6AS7/6080/6N13 power tube. Close to unity gain and low output impedance make this ideal for headphone amplifier. A proven favourite with OTL users too. In good supply and low cost.
12AU7 x 2. We all know this tube. Easy rolling and sound meshes very well with the 6AS7. It gives more gain but the reason is distortion is 10x less with 2 x 12AU7 vs 1 pc of 12AX7. The difference is noticeable to those with a taste for the high end.

• Solid chassis.. The Chassis is made of 4mm thick chassis and 7mm thick faceplate. Dimensions are 170mm x 310mm x 162mm (WxLxH). Weight 5 kg + shipping materials.

• Back panel.. Two pairs of gold plated RCA inputs and selector switch to choose source.

• Optional.. 4 x 0.1uf Obbligato tinfoil/teflon coupling caps $100.

ModWright HA 300 Headphone Amp ($7900)

Featuring the iconic 300B Single Ended Triode, the HA300 combines the functionality of Headphone and Integrated Amplifier in a 2-box 8 watt design.

The rise of World Class Headphones has driven the creation of Amplifiers to power them. The HA 300 combines my love of Headphones with a passion for Tube Amplifier design.

The 300B tube has long been known to produce the purest and most natural sound. It has gorgeous midrange and lush 3-Dimensionality. I have long been entranced by its sound, but found that 8W was not enough to drive many conventional loudspeaker designs. While I found the midrange to be beautiful, most SET designs I heard (with but a few exceptions, paired with the right speakers) fell short in terms of bass and high frequency response.

When a well designed 300B based amplifier is paired with modern Headphones however, such limitations fall away. Designed to provide 8 watts into 8 ohms, the tube amp is very happy driving the higher impedance loads of modern headphones, ranging from 23 ohm to 60 ohm, up to 600 ohm from brands such as Mr. Speaker, HiFiMan, Focal and Sennheiser for example. This means that the damping factor of the amp is higher, translating to superior low frequency response.

Power is the other factor. When we consider power requirements of even the most demanding of modern headphones, 8W is a lot of power!

When we set out to design a ‘Luxury’ Headphone amp, the 300B tube design just made sense!

Designed as a Class A, Single Ended Triode (SET) amplifier with zero feedback, the HA 300 offers the beautiful midrange of direct heated triodes without sacrificing detail, dynamics or bass response. It features an exceptionally low noise floor and robust power supply.

During the design process, we found ways to make 8 VERY POWERFUL WATTS, by way of a sophisticated external power supply design and over-sized core, hand-wound custom Electraprint Audio, Power and Output transformers. In so doing, we found that not only would the HA300 drive headphones with ease, it was also very capable of driving medium efficiency conventional speakers such as desktop monitors and even floor standers of 93-95dB efficiency and benign impedance curve, well!

The HA 300 shows its true strength and flexibility as the center of a modern integrated stereo system, for use with World Class headphones and speakers.

All HA 300 and PS 300 components are produced in Custom Automotive Finish and a variety of colors. Each unit is custom built to order.


Features
• Tube Complement: (2) 6BM8 Input; (2) 300B Power.
• Power Supply: External, SS rectified.
• Inputs: (1) Pair XLR, (1) Pair RCA, (1) 3mm Mini Jack.

Modwright SWL 9.0 AE.jpg (65.45 KiB) Vist 28837 gange

Celebrating our 17th year in business, the SWL 9.0 Anniversary Edition tube linestage is a tribute to our first product, the SWL 9.0SE. The SWL 9.0 Anniversary Edition retains the 5687 driver tube and many of its features, but is a complete redesign from the original. Unlike the original, the Anniversary Edition includes a modern headphone amplifier and optional phono stage.

The SWL 9.0 Anniversary Edition was designed to offer World-Class Performance. It uses the best components and proprietary circuitry to offer a full, fast and accurate recreation of the entire frequency range. Bass is deep, tight and authoritative, with seductive midrange and high frequency sparkle. The tonal balanced is designed to be accurate and detailed without edge or glare. The liquidity and holographic imaging of tubes is present, without the ‘soft’ or ‘syrupy’ sound often attributed to tube designs. Use of the very linear 5687 (also 7044/7119/6900 and suitable substitutes) driver tubes and SS rectifiers allow for low distortion and exceptional musicality.

Top quality parts are used throughout the design, including proprietary custom designed MWI metalized, oil- impregnated polypropylene capacitors. Great care is also taken to insure short signal paths and power, ground, transformer and signal layout to minimize noise, allowing for the cleanest and purest audio signal. Every step in the design was taken to create a product that allows ultimate enjoyment of the musical experience.

Sideways Eight TL-818 Headphone Amplifier/Line Stage (price unknown)

Sideways Eight TL-818.jpg
Sideways Eight TL-818.jpg (121.39 KiB) Vist 57512 gange

Each pair consists of a power supply unit and a signal unit that contains the audio amplification circuitry. Vacuum tube rectification is used because it sounds excellent. Low henry, low DCR filter chokes are utilized so the power supply will be fast and agile. Shunt regulation on the main audio chassis provides an ultra fast low impedance power supply.

The main audio circuit comprises the 6C45Pi triode gain stage actively loaded by a hybrid 12HL7 constant current source. The output is capacitor coupled to the TL-818 autoformer that MagneQuest/Peerless has built exclusively for Sideways Eight Audio Labs.

The TL-818 is a special version of the autoformer that Ercel Harrison, the Chief Designer of Peerless, created in 1946 for MGM Recording Studios.

According to Michael LaFevre of MagneQuest, these autoformers are "labor intensive and very exotic in design, including double C-cores, several winding sections, interleaving between "primary" and "secondary", reversed windings, several different wire gauges, multiple paralleled windings, and custom brackets with lots of machine & finish work." The exemplary design and construction are realized in the listening evaluation: music that is dynamic and "live."

For headphone use, the TL-818 enables user-selectable output impedances for matching different headphones. For example, the exceptional Sennheiser HD-800 works beautifully from the 200 ohm position and the Beyerdynamic T1 is driven using the 500 ohm position. Final Audio Design's lively Pandora Hope VI and hedonistic in-ear monitors such as FAD's FI-BA-SS and JH Audio's Roxanne match well with either the 10 or 4 ohm outputs.

We look forward to sharing with you the wonderful sound of the TL-818 headphone amplifier/line stage. Sideways Eight Audio Labs also welcomes requests from audiophiles for custom creations. Whether it be all silver wire transformers from MagneQuest/Peerless or special all directly heated triode circuits designed around vintage Western Electric iron, we endeavor to bring the best sound quality to the customer.  We have over fifteen years of circuit design experience, using exotic gain/driver tubes such as Western Electric 101L and 102L, 26, 56, WE 396A, WE 417A, and 7788, and directly heated triodes including 300B, 10, 45, 50 2A3, and 845. Please do not hesitate to inquire about what we can do for your dream system!

Thivan 811_572 SE.jpg
Thivan 811_572 SE.jpg (126.62 KiB) Vist 26963 gange

The 811/572 single-ended Headphone & Speaker amplifier launched by ThivanLabs in late 2017 was the world’s first 811 tube headphone amplifier. Half a year later, Trafomatic, a European audio company, also released a headphone amplifier using an 811 tube. Thivan had an opportunity to experience this very amplifier at the Munich high-end show in May 2018 and afterwards became more confident in our own ThivanLabs’ product. 

The 811/572 single-ended Headphone & Speaker amplifier marks the return of Thivanlabs into the headphone amplifier market after many years of research to improve and enhance high-end headphones aimed at high-class customers. This amplifier model can be used with high-end headphones and loudspeakers to enjoy music of high fidelity at home. Such flexibility from the 811 Headphone & Speaker amplifier allows its users to be completely submerged in the world of high quality music without causing any disturbance to a third party, and yet, let them rock the room when it comes to sharing their music passion with family and friends.

The latest 2019 version of the Headphone & Speaker amplifier has been refined to enhance the users’ music experience by the interchangeable use of both 811 and 572 tubes. ThivanLabs is a pioneer in using these two types of tubes for its commercial designs of light tube amplifiers. Thivan’s single-ended 811 amplifiers have been technically developed for many years, and so far have been trusted by a number of domestic and international users. These products are currently exported to European markets and are sold by ThivanLab’s official international distribution agents. 

An elite feature of the 2019 Headphone & Speaker amplifier is the optional use of a 572 tube for the power stage. This product line hence comes in two official versions – the 811 Single-ended and the 572 Single-ended. After several months of technical tests and design optimization on this amplifier with 572 tubes, the company has finalized these two versions, raising music reproduction to a new level – live-like performances of authentic, smooth, detailed, and inspiring sound quality.  
 
The 811/572 Headphone & Speaker version also still inherits its predecessors advantage of being flexibly connected to two headphones simultaneously without any interruptions to sound transmission and quality.

Aimed at high-end headphone lovers, ThivanLabs’s Headphone & Speaker amplifiers have been tested and launched as products for high quality sound, namely:
– Denon AH-D5000 / 7000/7100/7200
– Sennheiser HD650 / 800 / 800s

Elekit TU-8150DX.jpg (89.2 KiB) Vist 57512 gange

TU-8150, being a little brother of TU-8200, is taking over some attractive features from TU-8200 to enjoy difference in sound, such as:
• 3 different connection modes - Ultra linear, Triode, and Pentode - selectable by a jumper plug
• Different tubes for rolling - 6AQ5 and 6V6 series - by using included 6V6 PCB adaptor
• Ample space for larger capacitors to give users upgrade options

So, what are the NEW features of this little fellow? The biggest point we believe is that the amp is designed not just for the stationary music players but also for portable audios. There is a preamplifier stage configured with an Opamp to resolve the problem of short of gain from a portable audio. The Opamp is mounted on an IC socket so that it can easily be exchanged with other commercially available Opamps. Each Opamp gives different taste in sound, so that users can take pleasure in searching a sound of their choice.

Also, portable audio lovers tend to use headphones/earphones, and as a matter of course, TU-8150 is equipped with a headphone jack. Moreover, the power to drive a headphone/earphone can be selected from 3 options by the combination of 2 resistors per channel. Users can select a combination most suitable for their own headphones/earphones.

Elekit TU-8600S (Kit w/o tubes $1300)

Elekit TU-8600.jpg
Elekit TU-8600.jpg (196.75 KiB) Vist 53176 gange

TU-8600S is a third generation of TU-8600 series, a 300B single-ended tube amp kit released as a limited production model for 2017 and 2018, ran out so quickly. Receiving many requests from both domestic and oversea markets, we are again reproducing it as a revised version TU-8600S with minimal modification to the parts layout on the PCB from TU-8600R. Limited production, without tubes.

Features
• New active automatic bias adjustment system.. For the 300B tube bias, the power supply is equipped separately,and a ”New active automatic bias” is used where the amp detects plate current and automatically adjust the grid voltage. This design earns TU-8600S the priviledges of both self-bias and fixed bias. In addition, current detecting circuit is moved from the cathode side to the B-power side resulting in even better sound quality.
• Driving 300B tubes to full power.. A very orthodox design is used for the voltage amplifying stage to bring out the outstanding characteristics of the famed 300B tubes. Of special note is that 12AU7(ECC82) is used in parallel for the 2nd stage to drive the 300B tubes to full power- resulting in 200Vp-p without clipping.
• Tube-friendly design.. Warm-up time for directly-heated and indirectly-heated tubes largely differ. In most designs, amp power-up starts heating both the directly heated 300B tubes (fast warm-up) as well as the indirectly-heated 12AU7 and 12AX7 (slower warm-up). In TU-8600S, the 300B tubes are heated after the indirectly-heated tubes have warmed up. A very tube-friendly design that will not overload tubes that have not fully warmed up.
• Power circuit enhancement.. A high efficiency, low magnetic flux leakage R-core is used. The rectifier consists of schottky barrier diodes that require shorter recovery time. This results in a reduction in even negligible noise spikes.The windings of the power transformer include individual windings for the filament heater(A- Power), high voltage (B-power), and bias to stabilize the Negative Feedback (NFB) circuitry(C-Power). In addition, all power is stabilized to reduce residual noise as much as possible.
• Stable NFB circuit for great audio quality.. To make the most of the 300B tubes, the characteristics of various parts and circuits, including OPT, have been improved. The NFB is applied to the cathode of the 300B by the third winding of the OPT as well as to the voltage amplifying stage. Consequently, the overall NFB is minimized as well as the chance for the transient response.
• Ample space for larger coupling capacitors.. Capacitors can have a big effect on sound. TU-8600S uses high quality conductive polymer hybrid electrolytic caps and polypropylene film caps. For those who wish to use other higher quality caps, there is ample space provided on the PCB for mounting larger caps.
• Output level selection for headphones.. The headphone volume settings and the color settings of the power LED can be changed by moving the jumper location on the PCB.

Elekit TU-8900E (kit w/o tubes $1475)

Elekit TU-8900E.jpg
Elekit TU-8900E.jpg (116.44 KiB) Vist 20287 gange

Directly-heated triode tubes like the 300B and 2A3 enjoy an enduring popularity among audiophiles. The 300B with its rich midrange and extended bass - and 2A3 with its delicate expression and gentle tone - they offer a very special sonic experience. These 2 tubes, similar in appearance but very different in characteristics, can both be used in TU-8900 without any special changes in amplifier settings. Many manufacturers are producing 300B and 2A3 tubes so users can enjoy trying the various versions available in the market.

Features
• Automatic detection of 300B and 2A3 tubes.. “300B” and “2A3” tubes are similar in the appearance. However, since their filament voltage and the operating points are totally different, the supply voltage needs to be adjusted when using these 2 tubes in a same amp. In TU-8900E, the tubes mounted are automatically distinguished and a filament voltage and a voltage of B-power are automatically set. When 300B tubes are mounted, the sides of the volume knob light up in blue, and in green when 2A3. In addition, these LED lights on the right and left sides of the volume knob turns red when there is excess current due to defective tubes, etc, and the current is shut down to protect the amp. This red light indicates the problematic side as well, i.e., right side of the volume knob turns red when excess current occurs in the right channel, and vice versa.
• Newly designed circuitry.. The power transformer is winded for the right and left channel separately to minimize the interference between channels as much as possible. For the filament power, the latest DC-DC converter of extremely low noise and high efficiency is adopted. In addition, schottky barrier diodes and fast recovery diodes are adopted as rectifying diodes, by which even negligible noise spikes are minimized. Consequently, users can enjoy music free from noise even when using a pair of high efficiency headphones. The main circuit of the power unit is unitized per channel as a module.
• Tube-friendly design.. Warm-up time for directly-heated and indirectly-heated tubes largely differ. In most designs, directly-heated tube warm up quicker than indirectly-heated tubes so consequently directly heated tubes are often overloaded. With TU-8900E, the voltage is gradually raised and reduces the level of overload to the directly-heated tubes.
• Easily change the feedback setting to NON-NFB.. Since the bare characteristic of triode tubes has good is already well, there must be not a few people who are eager to listen to the triode tube sound without feedback applied. In TU-8900E, changing the position of a short plug on the PCB can change the setting to NON-NFB. The gain level increases by approx. 8dB when NON-NFB setting.
• Updated more reliable tube sockets.. Our brainstorming with the maker, 4-pin sockets for 300B/2A3 has become very reliable ones. Tubes are securely kept tight in the sockets after mounted.
• High heat-resistant polycarbonate tube cage.. By IEC, International Electrotechnical Commission, a thermal limit is strictly stipulated depending on the material of each part, such as a chassis and a tube cage. In TU-8900E, as the top of the tube cage becomes nearly 100 degreeC due to the heat from the output tubes, we adopted polycarbonate tube cage with high heat resistance and robustness to comply with the said safety standard.
• Ample space for larger coupling capacitors.. Coupling capacitors can have a big effect on the sound quality. For TU-8900E, high quality conductive polymer electrolytic caps and polypropylene film caps are adopted. However, exchanging to other coupling capacitors is also possible. The maximum size of the caps that can fit in the space is 22mm in diameter x 44mm in length.
• Matching headphone impedance / volume levels.. You can change the headphone level by simply removing the front panel and change the position of a short pin.

Specifications
• Tubes: 300Bx2 or 2A3x2, 12AU7x2 or 12BH7Ax2 * Tubes are not included
