separate system for just music?


Is it a common practice to have a totally different system for your music vs. hometheater? Right now I have only one system that i use for both but recently I've been playing with the idea of getting a very nice amp for just stereo music. I have lots of speakers and can easily dedicate a pair just for music. If i bought a nice amp, and only want to use a cd to play the music, what else do i need to complete the system? Do i need a preamp? I have so far, speakers and a cd player. What else do i need to complete this? an amp and preamp? i want to make it as simple as possible. thx for your help.

I have maintained separate 2-channel and HT/secondary 2-channel systems for many years.
I have 2 systems in one. My 2 channel preamp has cinima pass through. I listen to mostly vinyl and is why I went this way. I am thinking of seperating the 2 system because of grounding issues though. If I did not listen to vinyl then I would have only 1 system and it wound be the HT system I have now. It sounds great for 2 channel digital sources. If you are going to a ht processor make sure you can update it with software. HT system change much more often than 2 channel. If you cannot upgrade it then you will be replacing it in a year or so.
IMHO.
I have 2 separate systems and am quite happy. The theater is no slouch. However, my 2 channel is a nice little tube set up with vinyl and cd. The theater is in my basement and is really set up for theater and 5 channel audio.

My 2 channel is in my office and is set-up for much better imaging.

Both are equal quality with totally different personalities. Yes, I change amps with my moods.
