Recommended Speaker List for Atma-Sphere OTL Amplifiers.

Just for education purposes when you say it doesn’t support the standard do you mean "it is not differential", aka duplicate stages + and -?

No- the balanced standard requires that the output not reference ground and otherwise is able to drive a low impedance. That is how cable immunity occurs- otherwise you’d have to pick your cables to get things to sound right and longer cables are out of the question.


Glen, if updated in 2015 then its a Mk 3.2 or possibly early Mk3.3; either way a good find! The plate on the front states the amp’s actual identity; the number after the dot is stamped in so will be a 2 or 3.

Question is will they drive high efficiency horns like the current klipsch heritage line. I’ve currently been trying  some modded heresy 3s with the thought to move to the new Heresy 4, Cornwall 4. Or La Scala in the near future.

@glennewdick

We've been showing with Classic Audio Loudspeakers for decades and they are pretty efficient; depending on the model 97dB to 105dB. The M-60s work great on most horn speakers and is probably the goto amp in that regard.Klipsch is no worries.

The amps can be updated with full warranty reactivation.


@wolf_garcia while the Shiit is certainly balanced, it doesn't support the balanced standard (like most studio and stage equipment does). Support of the balanced line standard is rare in high end audio. There are balanced tube preamps that do.

How does Tannoy & atmasphere match up? Especially in the bass department......

Very well is the short answer.
