Power Amplifier - Maximum Resolution & Detail!

Unfortunately all opinions are completely biased, and based on limited exposure. Mine is no exception. Warm means dulled highs, a common preference. I don't go by gear I have not had in my system because only the amps I have had in my system prove themselves. IOW, bright speakers may make a warm amp sound detailed under the right circumstances. That said, limited finances have limited my knowledge. Down to the point, John Curl's amps, Halo amps, are hard to beat and are the JC5 is the best amp I have heard in my system. My system has modified gear, the Lampizator DAC in particular went from impressive to amazing after using an adapter to change the tube to a 6SN7, and bypassing the coupling caps with V-Cap ODAM, AND Teflon CUTF caps in the Amber 3, and in the Don Sachs DS2, I bypassed the ODAM caps with CUTF caps. Source is a computer, and speakers are Caladans. One Caladan owner had previously owned Quad ELS57s, a compromised speaker, but still one of the best sounding speakers in many ways that I have always owned. Bass and volume doomed them in my system, but Caladan addresses that and more.

What kind of speakers do you have?  I would imagine speakers could make a difference.  

KRELL  

I have a pair of Krell EV 600's that push my Wilson Maxx II's.  They're class A bias so they get hot, but boy how they make my Wilson's put out!

Krell fits the bill, a good recommendation! Don't forget about the Marsh amplifiers, definitely known for their high resolution without brightness. No wonder you don't see them for sale anymore.
