Thanks guys for the "feedback". I've been wondering if the new features of the RR2160 along with the additional power would justify replacing my RR2150 with it. Currently I use the B speaker outputs to avoid the bass management circuitry of the A speaker switch. I do use a sub much of the time, but I run my current speakers full range and use the sub's crossover to augment low bass. (Sometimes I just use the 55hz EQ setting.) Also, I am one of those who had a problem with the bass management switch. I found that the 60hz crossover position was actually the real bypass!
