how to use same mains for ht and 2 channel?

I have to combine ht and 2 channel due to space restrictions. My mains are ACI Opals, the best component I own. I use a Sherwood receiver as preamp and to amplify the center channel speaker. Belles One and B&K ST-140 power mains and rears respectively. Will be hooking up a powered sub soon. My sources are a cheap mega changer and a JVC DVD.

I have not been satisfied with the imaging and bass of my system for audio use. DVDs sound fine - dynamic. What I am wondering is how to keep my receiver running my home theater, but to possibly add a new cdp and preamp for two channel while using my Opals as my main speakers.

I don't have unlimited funds, but I could sell off my amps to fund purchase of a quality used integrated and cdp or separates. Can add some cash if necessary, but I couldn't spend more than $1,000.

Thanks for any help you can give.
