Upgrading to Duo 300 XD Stereo Amplifier and Illusion Preamplifier from Krell Evo

My advice which I never seem to take is to keep and enjoy what you have. Your current amp and preamp are outstanding Krell products with beautiful build and sonics. If you’re satisfied now you might end up unhappy with the contemplated change which is going to cost plenty. I don’t know what else you’ve got but IMO new speakers would by far make the most difference in your system if you’re wanting something fun to change. 

Speakers are Harbeth 40.2 and the combo with Krell is superb. After 30 years of this hobby, I am enjoying the Harbeths more than any speakers I've owned in the past. I have had them for four years and have no desire to change.

I got my 375 XD amps 2 months ago.
They are incredible. Base, mids, highs; all done extremely well.
Soundstage is fantastic. I had a 302e, no comparison.

I almost went with Pass Labs, but my 375's eliminated that idea.
I feel that I have arrived.
Am totally satisfied.

i’m glad to see the new krell gear well regarded.
do you have the exact same system now that you used the 302e in? that’s the real comparison. i don’t have any krell gear right now but wish them great success. 

I am interested what other gear you are using with the new 375 XD amp?
