Need new amp...


Well, I have some options here:

1. Use the NAD C 658 and find a power amp

2. Use the MF m5si and find a dac

Problem is that I can't combine the two because then I would have two preamps. 

Any good recommendations for under $2000 and at least 150w per channel and a max of 230w (two channels total obviously, hence the MF m5si integrated amp). I have been looking at NAD and Cambridge, but the 150w NAD one is claimed to have "good" sound, but the 200w Cambridge one has "fantastic sound" but overheats and can't even be turned up all the way. Thoughts on those two and I am open to all amps.

If there are any dacs that are somewhere on the internet I am not aware of, it would also be great to know about those, two optical ports and 24/192 are the only requirements for the dac.

Thanks!

There's a used AVA Fet Valve 400R power amp right now on Audiogon; asking price $1500. This is a really nice amp, and because AVA products don't have as great resale value as some of the better-known brands, it's a bargain. There was a review of the 600R in TAS that raved about it; the two are supposed to sound the same, except for higher power in the 600R.
After some research, I have my heart set on two Schiit Vidar amps with the Freya + preamp. I have dropped NAD, MF, and Cambridge all together, so now I am yet to find a dac... I'll make a post to it on a different page.

Thanks for the help everyone
