The Sim Audio i-7 is a very nice Solid State integrated amp. My only issue is the price. For that kind of money - you could seriously look into buying separates. I personally would spend the bulk on a serious serious preamplifier (possibly a tube preamp) for $4500 - $5500 and spend the rest on the power amp. This will give you more power and more flexibility and likely better sound.

For example you might consider something like the Odyssey Khartago monoblocks or Shengya PM 150 monoblocks

The Shengya's are impressive - I am currently reviewing a set of them. The Sim Audio isn't even remotely in the ball park in terms of build quality.

Then preamps - sky is the limit.

Not to knock integrated's I own one and love it but when you'r in the $6k plus range there are plenty of separates options that IMO are tough to beat. Especially SS integrateds.

For integrated amps check out the Grant Fidelity Rita - downside is that it is a tube amp - err wait that's an upside. And it costs a lot less than the Sim Audio. IMO the Rita sounds better and is better built. But lugging a 100lb amplifier around your house is downside. http://grantfidelity.com/site/RITA-8...Tube-Amplifier
