Best 80-100 w Amplifier Available Under $4k Used?
I think Rep4ever's comments on damping factor versus watts is probably right. I can see the excitment that comes from switching to an amp that provides damping your speakers may need (mine don't). I think the recommendation of the Music Reference ... 
What makes a bigger change, dac or preamp?
Beauty or truth - to paradigms for system building, and possibly to key to the variety of opinions we get on the same piece of equipment. I liked the quote in the February issue of TAS, Neil Gader interviews John McDonald of Audience, and he said ...

There amps that never leave Class A? For some reason, I think my CAT JL2 worked that way, but not sure if that is even possible. Techheads?

What is the input impedance of the Audiosector?

I think it switches at some point to B for handling peak power demand - I'm sure it is addressed in the Stereophile review, perhaps Magfan can confirm the data from Atkinson's tests. 
What makes a bigger change, dac or preamp?
Yes, the DAC is at the front (and I do believe you have to look from front to end, since you can't undo what is messed up early in the chain), but what if the differences between DACs are so small, that qualitative variance is relatively minor bet...

Ralph, I also think the XA30.5 is very conservatively rated, but one might still need the more powerful XA amps, even with "sensitive" speakers if they loaded up with drivers and x-overs. I think, but I'm not sure, that ight be the case with Petty...

Generally speaking I think Buconero117 is right - in most cases.

Pettyfeversk, your experience is with a multi-driver speaker and perhaps a 10" or more woofer? I'm thinking there is something about multi-driver speakers that makes a difference in the simple sensitivity/watts equation we normally make - seems th... 
Lightspeed Attenuator - Best Preamp Ever?
When I say source,I mean the recording, not the live event -there simply is no direct connection to it, but the recording is the reference for purposes of the argument here - true to the recording is proabably better language than saying true the ... 
Lightspeed Attenuator - Best Preamp Ever?
In the February issue of TAS, Neil Gader interviews John McDonald of Audience, and he said something that somehow seems related to this thread:"At Audience,the Golden Rule is 'first, do no harm,' defining harm as any deviation to the original reco...

Your speaker seems well suited for what SS can provide - current and damping- good thing air-condition is readily available in Florida - though, I would say the M60s threw off more heat than the XA30.5. There must be a Agoner XA30.5 owner somewher...

Well, either way, you will own some very fine equipment, with what you have, or what you are considering; everything mentioned on this thread could be the basis of an excellent system, so I don't think you going to wrong with the options you are c...

Like I said, if an OTL can drive your speaker, it is going to beat and tube amp with transformer IME. The M60s replace the CAT JL2s which they are many folks that consider it one of the very best high powered tube amps available; and I do think th... 
Lightspeed Attenuator - Best Preamp Ever?
It is linear. I, we?, sometimes hear what I expect to hear, at least in the short term.
