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


I have Krell Evo 402e Amplifier and Phantom Pre Amplifier. I am totally satisfied with this system. However I am thinking about selling and buying the new Krell Duo 300 XD and Illusion Preamplifier. Please share your opinions on the wisdom of this. Is it really an upgrade?

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 upgraded from the Krell FPB 700cv to the new 300xd with the ibias and also changed out my KPS25sc to the Krell Illusion II plus i changed my cables over to

Silnote Master reference series xlr  to connect the pre to the amp and i also picked up the 8 foot. Pair of Anniversary II Master Reference Speaker Cables and also got a pair of 1.5M RCA Orion-M1 Referance interconnects for my Tandberg 3001A tuner.  Sure i spent some cash but what a difference over my 20 year old gear, the only thing i have left are my B&W 801 Series 2 to change possibly but that will take a while before i get to them. I just can't say enough about my new gear....
