Best Class A amp with SLAM

Same thought as Unsound, why did you sell them if you were pleased with them?

The ability to weld and sound sweet are not necessarily mutual qualities!

If the Krells were working for you how about find another set??

"why did you sell them if you were pleased with them"

Isn't that what audiophiles do? IE get rid of stuff that already sounds good in hope of getting something better? :-)

OR sometimes of course things just break or need service to perform well again and people just decide to move on. Audiophiles are picky listeners and when the sound seems to change for the worse, even slightly, it can be very hard to figure out why and easier to just move on. It's an in-exact science in many ways.

Sounds like you would be happier with new speakers, not new amps. Smaller woofers = quicker bass = slam……

Have been to a lot of live venues and never heard much slam.
