The a1 is our compact, yet no compromise 35W power amplifier, it’s highly optimized hybrid design based on a 6922 tube buffer stage and series feedback provides a delicately transparent, yet lush and musical reproduction with zero harshness. Tonal sophistication simply unobtainable for audiophiles at this price before.

The magic transparency and delicacy of a SET amplifier – minus the limitations.

The .a1 features a exceptionally well implemented hybrid tube/solid state design which gives you the best of two worlds: the delicacy and transparency of the best tube designs with the superior current delivery capability and damping factor of solid state devices.

Tonal density and colours, preserved.

Most solid state amplifiers, par the most expensive and esoteric ones on the market tend to grey out the sound: harmonic and textural density get washed out, harmonic fullness disappears, what remains is a etched, brittle image of the music, which – although detailled – fails to give genuine satisfaction. The .a1 preserves the recorded material full texturality. A piano a piano, a voice a voice, in full color, in full flesh. A level of tonal sophistication rarely accomplished by any amplifier at this price point.

It’s mass loaded.
Keeping microphony out.

The .a1 weighs a healthy 6.5 kg, courtesy of it’s casing assembled from 8mm thick aluminium plates and the powerful 250VA toroidal transformer at it’s base. This high mass, as well as the sealed enclosure ensures that it’s 6922 vacuum tube is kept quiet inside, guaranteeing lowest microphony and solid imaging.

Highest quality components in all critical signal path locations.

We obsessively curate and fine-tune our selection of components and use highest quality parts in critical locations, such as Charcroft Z-foil ‘naked’ foil resistors – the lowest noise resistor money can buy – and the new range of ClarityCap CSA caps with CopperConnect™ technology. These measures afford the .a1 remarkable increases in terms of transparency and abscence of grain.

“The sound of the .a1 surprised me from the onset, it was modern yet vintage, reminiscent of the sound of single-ended tube amps but with that rock solid confidence in the bass. Best of both worlds”

Tube rolling
with the best.

The .a1 uses one single dual triode, the venerable 6922/E88CC. We opted for one single triode as it allows you to allocate more funds on one single, highly specced and tightly matched tube instead of needing to buy two, this will ensure highest bang for the buck … Suddenly, those super rare cryo treated 1960’s Telefunken tubes are within financial reach. Be part of the magic.
