Tube amp for "difficult" speakers,,,

The Consequence is not that hard a speaker to drive. We've had customers who have had good luck using our MA-2s. That's 220 watts of triode power FWIW.

Asa, FWIW any Atma-Sphere product that gets updated to the latest level gets warranty reactivation. In addition, the warranty is transferable. This helps with the resale value on amps like the MA-1, which don't tend to hang on audiogon all that long.

Acoustat 2+2s are easily driven with a set of M-60s and a set of ZEROs. They are not a power-hungry speaker.

Hi Mark, the trick to driving Accoustats is being able to deal with the load. A friend of mine had them- wicked low impedance- but we ran them with a set of M-60s and a set of our Z-Music autoformers to deal with the load. They sounded fabulous and could play any reasonable volume- we never ran the system out of power. He had an ARC too; it needed the autoformer as well!

These days you get a set of ZEROs (we don't make the Z-Music anymore) and a set of M-60s will do the job. You would need them even if you had MA-1s; Accoustats are a 'difficult' load, and the ZEROs can be looked at as a great problem solver for things like that. IOW a great way to get a tube amp to drive a problem load.

People often ask if there is a degradation, which is a sort of Red Herring; obviously if the amp can't drive the load 'without', and it does it great 'with', then the answer is 'no, it works great!'
