Suggestion for best stereo amp ?


Hello,
because of severe WAF, I must limit myself to stereo amp. After several years of happiness with my Krell Evo 402, I am starting to think there must be upgrades possible. Any suggestion ? For your complete information, I have a Krell pre-amp Evo 202 and loudspeakers are Wilson Audio Sasha.

What I most enjoy with my Krell: no limit to pure power, great bass and tight control. Enjoyable from very low level.

thank you in advance for your help.

I would get the Dan D'Agostino Momentum M400 monoblock power amps or the Momentum stereo power amp with the Momentum linestage preamp. 
This will be a great upgrade path.

You are getting performance that’s a bit worse than the $15K PS Audio BHK 300, so not worth its $55,000 price tag unless the looks are really for you. Also, not saying the BHK 300 is the best for the money, just giving a comparison.
