Probably one of the Best Single-Ended Class-A Monoblock Amplifiers Ever Built!
Our top end product – the PA-1 Power Amplifier. Built completely discrete with 2 monoblocks, one for each channel.
The design of this amplifier is fundamentally different to all our other products and offers probably the purest way possible to amplify your precious music. No matter if it’s rock, classic or electronic beats, the PA-1 will be a very satisfying partner. The class-A amplifier design features 300B vacuum tubes and is absolutely discrete, one block for each channel complete with separate amplifier unit and power supply.
Check out its features and please remember that you require a Pre-Amplifier in your setup in order to use the PA-1.

Illuminated VU Meters
The illuminated VU meters are not just nice to look at but provide information on the power output of the amplifier
300B Vacuum Tube
The setup utilizes the well known 300B vacuum tubes. 300B tubes can easily be replaced by alternative brand tubes to further adjust to your preferred sound qualities (the tube we deliver reproduces a very neutral sound)
Highest Quality Circuit Components
Same as our other products also the PA-1 is solely made from high quality parts. But we took it a step further...
Circuitry with high-quality oxygen-free copper enamells, wires with pure pulp insulation.
Capacitors from Philips®, Japanese Chemical®, WIMA® and Siemens®.
Carefully welded German WBT solder used for all connections.
Dust Proof ALPS Volume Knob
Dust proof, long life ALPS27 volume potentiometer with excellent feel and accuracy
Power Supply - The Core of a Great Amplifier
Power supply with independent windings for high and low voltage sections securing highest degree of separation.
Excellent insulation for moisture resistance and longevity.
CLC Filter Circuit for Improved Sound Reproduction
The multi-stage CLC filter circuit has been designed to further reduce background noise and emphasise more details of complex musical pieces
Dual Monoblock Design
Dual Monoblock design to ensure 100% separation of left and right channel.
Separation of left from right channel is significantly higher than in all-in-one amplifiers
Heavy & Durable Made to Last
Top grade, heavy and solid casing made from aluminium and stainless steel.
Made to last (at least) a lifetime!
Sufficient Power Reserves
Don't be fooled by its power - the PA-1 easily handles also large floor standing loudspeakers and reliably drives them also for long durations at peak power.
Sufficient power to represent your favourite music with transparency and thrust
Filament Voltage Control Knob
Filament voltage adjustment knob on the back to tune the amplifier to the connected peripherals, optimise the signal-to-noise ratio and remove unwanted hum
Single-Ended Class-A Amplifier Design
Unique Serial Number
Each pair of PA-1 amplifiers holds its unique serial number. In our database, each serial number is linked to the list of parts contained in your amplifier as well as the names of the technicians who built it.
