I am thinking of getting a pair of M80's for my new listening room (currently under renovation).

To drive them I was considering a pair or Red Dragon M-500 monoblocks. $1400, see http://www.reddragonaudio.com/products/m-500-monoblocks/

My source is a Squeezebox Touch which I would connect directly to the monoblocks. I have no other sources, so initially I saw no point in getting a preamp.

My room is rather large, 4500 cu.ft., so in the future I might want to add a subwoofer. However, I cannot see how to fit the subwoofer into the Touch/M-500/M80 configuration?

A thought: Instead of the M-500's I could get a pair of Monarchy Audio SE-100 Mark 2's (also about $1400, see http://www.monarchyaudio.com/SE100MK2.html). These have an extra XLR connector which can be used for bi-amping. Could I use the extra connector to drive a subwoofer? Would I need to get two subwoofers (left and right)?

My budget is a strict US$3000 for amp + speakers + cables.

is this the squeeze box your talking about

for the red dragon amp how do you plan on going from RCA to XLR connectors? if you get a spliced cable, it will work, but its not using the full 3 wire design of the XLR...

you could get a Y RCA connector and send one of the outputs to the sub, and let the subs crossover take care of the high frequency attenuation.

Yes, that is the Squeezebox that I have. (Awesome sound quality, by the way, if you rip your CDs to FLAC or download stuff from places like HDTracks.com.)

The Red Dragon M-500 can be ordered with RCA input instead of XLR. They only have pictures of the XLR version on their web site.

Thanks for the tip on the Y-connector. I am now researching the interwebs for RCA Y-connectors ....

Have to agree the Logitech Squeezebox Touch is an excellent bit of kit both in terms of sound and interface. For the price theer isn't much that can beat it.

I still want one, but I haven't gotten around to it yet.
