The setup Bdgregory describes is a good option. I participated in the thread that he referenced and agree that it is a good way of doing things, especially if your priority is a "no compromise" 2-channel system, but one that will also do HT.
I call one of these systems a "combo system". First, you build a quality 2-channel music system, then you add HT functionality to it. The added HT equipment does not have any affect on the 2-channel primary system.
So, in a combo system, you build the 2-channel rig by using a quality pre-amp and power amp, or a quality integrated amp. You connect 2 speakers and add a source and you are done with the 2-channel portion. For HT duties, you buy a decent HT receiver with pre-outs (for at least the front L&R channels) and connect it to your pre-amp/integrated amp using either any open input jacks or a dedicated HTbypass/processor loop (if your pre-amp has this feature). You connect the center speaker, surrounds and sub to the HT receiver and connect your HT source (DVD player, cable box, TV, etc.) to the receiver for processing.
To play music, just use the 2-channel rig. No need to even turn on the HT receiver as it is not part of the system. For HT, also turn on the HT receiver and select the appropriate input on your pre-amp. Now the 2-channel rig is part of the HT system, acting as the amplification and front L&R speakers for the HT setup.
It sounds more complicated than it really is. I think it is a good choice for many people with a 2-channel music priority. It doesn't compromise 2-channel at all, and adds good HT to the mix.
I've had a combo setup on numerous occassions and it worked well.
I also like my previous idea of the Linar model 10 driving a 5.1 speaker setup!
Enjoy,
