Re: Seperate amp for mains

>>Unfortunately my tube amp is a little to short on power. I'd say around 25W/ch.<<

You did not mention your brand and model of speakers. You would be surprised, given the right set of speakers, how loud 25 watts can sound. When I mean the right set of speakers, I am referring to the impedance and sensitivity of the speakers. In my system, I use the 12-watt/channel Audion Sterling single-ended tube amp (using RCA 7027A output tubes) to drive my Joseph Audio RM50si speakers (88 dB, 8 ohms nom/7.0 ohms min). When I do HT I can turn up the volume as loud as I can stand and still not run out of power. In fact, I have measured 100+dB peaks for HT without and strain or compression. I don't actually listen at those levels as I value my hearing too much, I just use it as an example of how far a small amount of watts can go.

>>Any problems with letting an amp sit idle? I assume not since they provide pre-outs.<<

This should not be a problem.

>>Also, if I use the receiver to drive my mains, do the receivers typically have a main in. See, my subs are matched to the mains using an active crossover. I would go pre-out -> active xover -> hi-pass to main-in -> low-pass to my subs power amp (Perreaux 2150b) -> stereo subs. Therefore, I would also not need the sub out of the receiver. Any problems with this?<<

Some receivers have mains-in and some don't.
