Most transparent power amp

Wilson Audio Sasha break-in time ?

I take it from this speaker thread you started, you have the Sasha’s, then my last statement in the 3rd paragraph,
" and one that is able to drive your speakers without becoming a tone control." should be well considered.

BTW OTL’s and most tubes, even mosfets have no chance driving the Sasha’s without becoming a tone control, you need current at low impedance for these speakers for the amp to stay flat (transparent) across the frequency range.

Stereophile: " Sasha's plot of impedance magnitude and electrical phase (fig.1) reveals the speaker to be a demanding load for the partnering amplifier to drive. Not only does the impedance drop below 4 ohms for most of the lower midrange and upper bass, with a minimum value of 2 ohms at 86Hz, but there is also an amplifier-unfriendly combination of 3 ohms and –43° phase angle at 61Hz."

^^ FWIW we've had good luck with Sashas running our MA-1s. I think it might be helped by a set of ZEROs (www.zeroimpedance.com) but the amp didn't sound like there were any problems making bass despite the Sasha's rather low impedance in the bass region.

I can't speak for other OTLs out there. But since we don't run any feedback, it seems that our amp should have been a problem on that speaker. This leads me to believe that Wilson may have used a tube amp during the design phase of this speaker.

Hey Ralph. Here's my chance to zero in now that you've chimed in. My experience has been that there's no free lunch. What is the compromise in implementing the ZEROs? It seems you would lose extension one way or another, no?

What is the compromise in implementing the ZEROs

Easy, you can hear/do this for yourself. On any amp that has no problem driving whatever speaker without the Zero’s. Then put the Zero’s in and you will then hear the compromises they make.
But they do allow amps that are not driving the speaker well, to be able to do so, but I’d rather change the amp for the right one for those speakers, as these Zero’s are not cheap, for what to me is a band-aid fix.
