Great integrated amps with narrow depth under 12 inches?


Trying to upgrade my NAD C352 2x80 watts amp into something... well, better. The NAD isn't known for lots of details, and with my Gallo Strada speakers, it's probably a significant bottleneck. As for power it's probably enough.

But the depth of some of these amps are killing me! Unfortunately for WAF reasons the amp must stay in the TV bench and 12 inches is the absolute max depth.

Suggestions? Build-in DAC would be a plus, as would room correction (that's probably asking too much?)

The Bells Area is unfortunately too large, albeit only by a bit. As is the Hegel. But thanks for all the suggestions everyone! Still considering the Nuprime. Also considering keeping the amp and getting a miniDSP with Dirac Live instead. Of course that's upgrading the sound in a completely different way, but still. 
Thanks for the tip, the Bel Canto should fit. I must admit I have no knowledge of this brand, but I guess I should start reading reviews etc. What sound characteristics would you say the 5i have? And does it do well at lover volumes?
Carlings, you've found the Nad lacks with detail?  Have you ever experimented with replacing the preamp jumpers?  When I did this on my C326BEE, added highs gave more resolution.  I've also owned the C372 and found it laid back, but I never replaced the jumpers on that one.  But the detail available with the 326 is actually pretty good for a budget integrated amp, though I've got upgraded speaker and RCA cables as well.

If you have some extra  good quality rca cables, it might be worth a try.
