@jay73 I have a Rotel RA-1572 and this may or may not be of interest.
If you listen to rock music, be aware that busy and/or dense passages of music don't work so well with the RA-1572. When the music gets busier / denser, the bottom end all but disappears and the sound stage becomes notably narrower. I did an A/B with another amp to make sure it wasn't something else at fault in the system but it's definitely the RA-1572.
It's frustrating because more laid back music generally sounds really good.
Tracks to test the issue include, say, "Enter Sandman" by Metallica; "Dark Star" by Fish (album 13th Star). Also, the heavier material by Evanescence.
One track that perfectly illustrates the lovely side of the RA-1572 but also the issue mentioned above is "Just Can't Let You Go" by Gary Moore (version from the compilation album "Beyond The Blues"). When it starts, it's lovely rich & bluesy. However, there are two heavier, denser, sections in the song and the RA-1572 really doesn't handle them at all well. I've played this piece on other equipment and the bottom end / sound stage are fine.
Whatever you decide, happy listening. :)
