You are right, Jkohn about the tone controls. It depends at what frequency the "hinge" of the treble control begins. The Rotel's hinge is much higher than usual, not uncommon in "audiophile" tone-control circuits. Most treble controls on mainstream receivers begin acting in the midrange, around 3 kHz.
This makes sense, because in the past when I've tried to lower the treble a bit for those problematic "bright" CD's I've found that it helps some, but not much, and at the same time it totally removes the "air" from the sound. I'm thinking with the resistors, I might actually be able to raise the treble a notch, since it's at 10k and would restore the "air" without affecting the brightness too much. We'll see, can't hurt to try...
