Atma-sphere 3.0 to 3.1

The 3.1 update is a change to the voltage amplifier. It affects all our amplifiers. The change reduces measurable distortion- by about 90% at full power.

Distortion has two audible properties in audio circuits, the first being that it causes harshness. The second is that it can mask underlying detail. So eliminating it (if done without using feedback) will make the amp both smoother and more detailed at the same time, and that is what people report when they hear this change.

Because it only affects the voltage amplifier circuit of the amp, its relatively inexpensive (if you already have the MkIII), but like we do anytime one of our products is updated to the latest level, the warranty is reactivated.

Atmasphere - sorry to hijack the thread, but since you are already posting in this thread, I thought I will ask you a question - do you think that M60 3.1 that is beeing descussed here will drive W/P Sasha in a small room ?

Elberoth2, if you use a set of ZEROs, it will be outstanding. The Sashas don't need a lot of power but the M-60 does not like 4 ohms. The ZEROs fix that and will get you double the power that you would have without them on that speaker, and you will have fabulous bass authority!

Atma - and what about the MA-1s ? Do you need all tubes to drive the Sasha, or can you take some out ? My main concern is heat issue - chance the idea of taking out some tubes.

Elberoth2, I've been listening to the Sashas with MA-1s a lot recently. They seem to work quite well together and is what I based my comments on the Sashas on over on the Speakers forum.

If you run the amps with less than the full complement, due to the low impedance of the Sashas the ZEROs will be helpful. Its a nice way to reduce the heat if you don't need the power and the Sashas seem actually fairly efficient. When I've been listening to them the VU meters on the amp barely move.
