We don’t have much to say in way of improvements for the RR2150. Its operation, sound quality, and measurements were all splendid. However, if we must nit-pick, there are three areas we would comment on. First, as previously mentioned, the remote doesn’t fit with the rest of the unit. We would like to see a remote with a more high-end feel and a button layout focused on 2ch. stereo systems, not video related equipment. Second, the inclusion of digital coax and digital optical inputs would be a bonus. Since the RR2150 relies on the DAC inside the source equipment (other than for the USB input), consumers need to invest in a good transport. If the RR2150 had digital inputs, then consumers wouldn’t have to worry as much about having a nice transport. Finally, crosstalk measurements were good, but not as stellar as we’ve seen in comparable products. The Harman Kardon 3490 we reviewed ($499) measured considerably lower here.  However the RR2150 amp section is more meaty than the HK 3490.  In fact it has one of the best amp sections we’ve seen in a two-channel receiver.

Conclusion

In a marketplace full of “modern” black receivers with flimsy faceplates and minimalist designs, the RR2150 is a breath of fresh air. It doesn’t look “old” or “cutting-edge”. Rather, it strikes a nice balance between retro and modern. That theme of blending past and present weaves its way into the feature set as well, with the presence of USB and Subwoofer connections. At the same time, the RR2150 remains a classic stereo receiver with tons of power and enough analog inputs and control knobs to make vintage gear blush. In fact, it's the most powerful two channel receiver we have ever measured! Great looks, features, build quality and power at an affordable price, we're not sure what else you could ask for. Whether your speakers are just released limited edition or were made before Jimmy Hendrix picked up a guitar, the RR2150 would make a great piece of gear in any stereo system.
