Einstein OTL amps experience

Hey DocS. As an A/sphere MP-1/M60 owner running them on Duos, I can only say that I wished I lived in S Fla. to be on hand for this most interesting sounding shootout. Please keep us posted. I think the worst possible outcome will be a great one.

Docsavage - pls keep us posted.

I forgot to mention that the amp portion of this shoot-out will also include a set of EAR 519 push pull 100W tube amps and a set of Bryston 7BST high power ss amps. I will include these in the game for overall evaluation of power requirements etc.
BTW for another little shoot-out I will be comparing tonearms on my Galibier table set up for two arms using Schroeder Reference SQ and a Tri-planar VII.
Two carts will be used. A Dynavector XV1-s and a VDH black beauty.
The next several weeks should be fun.

Hi Doc, what kind of MA-1 Mk.IIIs do you have?

It is possible I am mistaken here but to be exact my Atma-sphere amps are Ma1 Mk 2 Silver edition upgraded at the factory with power supply boost and Caddack resistor package. I thought the upgrade brought the amps to mk 3 status as well except for the auto bias which I really had no interest in having. BTW the improvement is much more that subtle after the upgrades and tube life and reliability has been improved beyond what I thought possible. I use to drive stats with the amps and they sounded great but the difficult load caused what I would term premature tube failure. Once the mods were completed I had no tube failure even when driving the same stats. It has been about 1.5 years since the upgrade and I have not had to replace a tube. The load with the Acapella speakers is much more benign.
