This is a demo pair used at the Newport Beach Show in June. It’s in mint condition and comes with original boxes and warranty. This is a 120V unit for the US and Canadian market.
Wall Audio is a company in Freiburg, in the south of Germany, making tube amps since more than 30 years and finally available in North America.
The M 33 SET uses one NOS 6C33C-B triode in the output stage and NOS ECC82 input and driver stage. The monos deliver 18 watt per channel, pure Class-A with no negative feedback and the sound is just gorgeous!! One reviewer in Germany once called them "...a gift from the HiFi gods".
If you use single driver or high sensitive speakers (>90db) these monos might be what you always have been looking for.
Here some more information from the Wall Audio website:
We want to start the introduction of Wall Audios latest work, the monoblock amplifiers M 33 SET, unconventionally with a gratitude to the brilliant Lee De Forest. His invention in 1906 – the high-vacuum triode – allows audiophiles all over the world up to this day a unique sound experience.
Our monoblock power amplifiers are built on the base of this wonderful invention and include this high-vacuum triode as an essential feature. Therefore our amplifiers could convince connoisseurs in a playful way.
One of the advantages of our monoblock power amplifier M 33 SET is the automatic bias, so no maintenance is required – even at a necessary change of tubes no corrections are necessary.
Special features:
No negative feedback!
