New Krell s300i vs. the older 400/300

I see that Krell has snuck in a replacement for the 400xi.
I know that there has always been debates over these
int amps.

Nothing on the Krell website yet. I have seen the specs and it looks like a good product. I have used a 400xi before and really liked it. My only complaint that it seemed hard to get the right sound at lower listening levels. No problem when you wanted to crank it up. I used different speakers.

Just curious if any Agoner's have used the new int amp.
Maybe I may look at the older 300xi. It seems that this is the sleeper.

Any opinions on the two different 300's from Krell would be helpful.
