Class-A Output Transformer-Less Headphone Amplifier

Boasting a 3 watts RMS minimum into most audiophile headphones, this is not your typical OTL headphone amplifier!

With one tube stage for gain and another to provide the power, low distortion output, this amp has a very minimalist signal path and is very fast and natural sounding.

This amp is extremely linear and works amazingly with high impedance headphones, but works very well into loads as low as 32 ohms. Try it with headphones such as the Sennheiser HD800, Audeze LCD4 and Beyerdynamic T1.

Power Supply

A choke input, as well as an additional choke for filtering gives you a very clean and quiet power supply. Power is rectified with hyper-fast, soft recovery FRED rectifiers.

High quality film capacitors exclusively used throughout the whole power supply, which will vastly out outperform and outlast even the very best electrolytic capacitors.

Driver and Output Stage

A giant step up in audio quality from any potentiometer, this amp ships standard with a series-type 24-step attenuator, made in house. 

The topology used on the driver maximizes voltage gain and is extremely linear. Use your favorite 6SN7 type tube here.

The output stage is set up as a cathode follower with very nice active biasing, resulting in a high power output into most headphone loads. Use EL84s or 6P15P-EV tubes here.

We included some very nice NOS tubes to get you started.

[+$200] Teflon Film and Foil Capacitors.
This is a big upgrade over the standard film and foil coupling capacitors that come with this amplifier. Break-in time is long, however.
[+$250] 24-Step Ladder-Type Attenuator, made in-house with ultra low-noise, precision military resistors.
Ladder types are the best type of stepped attenuator, with only a single resistor in series with the signal path. A significant step up over any potentiometer (and most other stepped attenuators too).
