integrated amp recommendation needed

I second the Yamaha, perhaps the A-S1000(or A-S801) which can be found new at a friendly price. Quite powerful, smooth sounding, nice features plus excellent build quality. Just one of many options out there...

I've never heard it but the Outlaw Audio RR2160 has always piqued my interest. 110 watts in to 8 ohms, an assumedly decent dac, bass management for a subwoofer, and a headphone output all for $799.  Perhaps someone here has heard it (or the older model). 

There is a difference in the quality of watts. A Yamaha or Cambridge 100 watt amp will sound quite a bit different than a 100 watt amp for on Levinson/classe/McIntosh. That's why Revel wants you to use a quality amp for their speakers

There is a Plinius 8100 integrated amp here on audiogon. Looks very sweet for $650. Get a nice power cord and good speaker cables and I bet you would be in sonic heaven. There are also some sweet tube amps there too....Cayin, Jolida and Eastern Electric. Those tube amps are much more powerful than the rating. I know I have a Line Magnetic Audio push/pull and it sounds like a 100wpc amp.

Of course if you wanted something new, I would increase my budget $50 and get the Bluesound PowerNode 2.
An amazing product that could really transform your system. I have the Node 2 and the MQA playback is astonishing.
