Best Class A amp with SLAM

Maybe more powerful than what you are looking for, but I'm extremely happy with my Symphonic Line Kraft 250 monos. Big transformer plus big capacitance means big current available to fuel big dynamics, even on inefficient speakers like my Salon 2s. Fast as hell too!

Clayton M300 monos. 300wpc into 8 ohms, 600 wpc into 4 ohms, all in class A. With latest power supply upgrade, these seemingly never run out of steam. Can't say how they compare to Krell, and if slam only is your goal you should probably go back to Krell, but for the texture, naturalness and dimensionality that good class A can provide, as well as tons of power to drive a pair of Aerials, I have found these suit me well.

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.
