I am looking to buy a receiver/amp/pre-amp to power my Klipsch Chorus speakers. This is basically my starting point and I want to add to them. I don't have a ton of money (about $500-1000, maybe a little more) to buy a receiver/amp-pre right now (i will buy used). But, I would like to start buying pieces that would eventually add up to something nice. What should my next move be - receiver, separates? I am looking at the NAD, Rotel, CA, Arcam, etc. gear. I don't want Onkyo, Sony or Yamaha type "Best Buy" gear. Give me something that is, at least, a step above these entry-level pieces. If they cost much more, then so be it. I am looking for something not only now but something with future value too. My space is moderate (20X15 or so). I will definitely add a center speaker and maybe a couple of rear speakers in the future. However, I have a couple of Polk bookshelf speakers to pair with these, but they are clearly inferior to my Klipsch. I will probably never have seven speakers so 7.1 is not important. I do watch a lot of movies and listen to XM on DTV, along w/CDs - probably 50/50 CD/DTV. I have a Toshiba 46" HDTV with 1080i that I will have hooked up with a DTV HDTV receiver. I don't know that much about all of this, but I have tried to give as many specs as I can so that hopefully somebody that knows a lot more than me can give me some suggestions for amplification and further speaker recommendations...
