The Ayre AX-7e for $3000 retail is a great integrated. I used to own it and thought it better than the 400xi if you don't need gobs of power. But it's a very different sound and not the type that will "blow you away"--its charms are much more subtle. As usual, system matching, especially with the right speakers, will be critical. The $2000-$3000 range of integrateds is a very rich field, but since you're already a Krell type of guy, I'd say stick with the 400xi. Otherwise, strap yourself in and be prepared to shop for a good while--there are just so many choices out there.
