Great integrated amps with narrow depth under 12 inches?

I would try a 30 day home trial of the Nuprime IDA8 through NuPrime or one of its authorized internet dealers and, if you have a local dealer, the Hegel H80. There also may be some authorized Hegel dealers that would give you a similar 30 day trial.These are both great amps with built in DACs, with similar super quiet backgrounds, great detail and bass control, but different personalities. They also both sound bigger than their specs.

@213runnin, no I'm not disappointed with the C352 per se, but reading around, a lack of resolution seems to be a common complaint so I figure this would be a natural upgrade path as my speakers should be the strongest component at this point.

Thanks for the suggestion, I might replace the preamp jumpers with an RCA cable.

The NAD 3020d is a giant killer . Try it $400 .

As I mentioned previously, I have the Hegel H80 and finally measured it- I don't think it will fit, once you hook up RCAs and speaker wire. I also have the NAD D3020. It is a giant killer- excellent detail, smooth with black background. I did not compare the NuPrime directly to the NAD, I was comparing it to the Hegel. I would say the IDA-8 has all of the strengths of the NAD but a significantly more robust bottom end and even more detail and openness. Again considering the price difference, I'd try to arrange a couple of inhome trials- buy them from reputable authorized outlets with a good return policy.

Hegel is great.  Also check out the Cyrus products, including The ONE.
