I picked up an RR2160 and it has been great. The sound is very well balanced with what sounds like a slight emphasis on the highs. It provides a very detailed image. Things like the sleep timer, remote, and internet radio are all things that I can't picture doing without now. I tend to throw the internet radio on, with the sleep timer, and leave it playing before I hit the sack. When you open up the RR2160 ( caution: the cover wasn't the easiest to get off and I almost marred the unit doing it) you can very easily see the dual monoblock design. From the previous picture of the RR2150, which I remember reading about in Stereophile recommend components, the RR2160 looks like a much better design. From my perspective if I ever need to service the unit down the road and don't want to send it in, the dual monoblock layout should make it much easier to check the other channel and trouble shoot.
In terms of reliability, I've only had the unit for a month or so, but I actually had the suppressor cap fail on my old Dual 1219 and it put out a nasty turn on pop right through the phono pre-amp of the RR2160. After, the left channel on my RR2160 would not play audio through the phono and only reproduced some noise. I turned the unit off and had it sit over the next day and a half, I fired it up again and the RR2160 was playing just fine with a friend's Pro-Ject TT! That beats having to try and smooth talk Outlaw for a replacement receiver! As the dual's motor went up in smoke not too long after I replaced the cap, I've now picked up a Denon DP300F, and will run it through the phono stage of the RR2160. I am sure you will hear from me on the DP300F thread once I get it.
P.S. In terms of noise, the unit is quite quiet. Djcoolray, THD has nothing to do with noise floor. Total Harmonic Distortion is better thought of as a measurement for how accurate an audio signal is reproduced. Think of it as the amount of harmonic content that is added to the original signal. .05%THD is inaudible and as 62caddy said, your speakers will be higher than this. A better specification for noise floor would be SNR at 1watt.
