help me to build...

I second Kennyt's suggestion, for alot les than a plasma you can get a real nice DLP TV that is pretty thin. you cannot hang them from the walls, but you can get em about a foot deep, and you will not have to worry about burn-in and the black level is waaaayy darker on DLP than plasma, and have a bigger screen size. It does not have quite the Gee-wiz factor, but if you check out some of Samsung's DLPs you might be pretty satisified with the asthetics of them. They certainly dont look cheap.

If you have pre-outs on yer reciever you also might want to look at getting a multichannel amp. I used to be a big reciever fan, but after finally hearing a seperates setup it is hard to go back to a reciever.

To get more info, you might want to give us an idea of the budget yer looking at.

Nah, forget plasmas/LCDs and even RPTVs. IMO get an inexpensive digital front projector. Get thee to the AVS forums http://www.avsforum.com/avs-vb and lurk in the Digital Projectors - Under $3500 USD MSRP forum. you'd be surprised how big and glorious of a image you can get for the same price or less than an RPTV. My $0.02. YMMV. If you have decent light control, anything more than 750 lumens is great.

Why settle for 65 inches or less when you can have 84, 92, or 110 inches? And sit thee at 1.5x or 2.0x the screen width. I prefer 1.85x the screen width myself. I sit about 11 or 12 foot from a 80 inch wide screen (92 diagonal). It's great for immersion into movies and concert DVDs. Bravo!

That and heed slappy's recommendation for a separate amp, since this is for music. You might be able to use a receiver as a pre/pro, or a even a used or b-stock pre/pro, like an outlaw audio one.

thanks, guys for the advise...but what about cables ?

I you're happy with your AQ's, why not just get more? Other inexpensive cables that I've tried and liked are Goertz and Signal Cable. No sub?

Well yes, but , this is step by step, Quad is comming with a sub for the L series,just waiting and see...
