Looking to upgrade

Thanks for the suggestions. Elevick, can you recommend an inexpensive line conditioner? I think I'm going to pick up a Lexicon DC and also take a look at B&K amp. Regarding price range, around $2000.00 to upgrade. Is it best to spend the money on processor and amp, or should I be looking to change speakers. BTW, 100% of my system is dedicated to TV/Movie surround sound. I never listen to 2 channel stereo.

Bob, if I upgrade to Evolution 5 or 6 do my NHT VT-3 still work okay as surrounds or do those need to be upgraded as well? Thanks

I'm now totally confused :). Charles, I currently have a PS3 so Blueray player is covered. Last PS3 firmware update added upscaling to DVD's as well so I'm quite pleased with this solution. Regarding my display, I have a Pioneer Elite RPTV that I bought about 4 years ago. Great TV but it's big (about 300 lbs). I'll look into the AVR-300, Rotel, and Linn. I think separates are right for me, I'm not sure if the receivers mentioned would be much better than my current Marantz receiver.

Newmanoc, what electronics would you recommend for a proper upgrade?
