There are lots of good choices. A few questions and answers will help narrow down the suggestions you get. What is your budget? Do you want an integrated amp and dac in one unit or can they be separate? How will you stream your music (e.g., via Bluetooth or some other hard wired source like a network music streamer like Cambridge cxn)? I just ordered the forte iii myself and am still trying to figure some things out as well. I will likely hookup sonus to my preamp/dac.
A very simple and inexpensive solution would be a Yamaha S801 integrated with built in dac for about $900 and then buy a separate Bluetooth device ( less than a 100) that you can plug into you Yamaha and stream music from your iPhone
