new AVR ? or revamp

First upgrade the sub. You can add an Emotiva xpa5 and use the recvr as a prepro. This will kick things up to whole new level. You will be all giggles. I suggest Svs, Hsu, Ed, or Epik subs. Get the most you can afford. A good sub will never go out of style. You will upgrade everything thing else and the sub will still be in the rig. Shop here for a killer deal on a clean prev owned sub. What ya' waitin' for? Btw...your choices are nice and would make for a great platform from which to build on. How about the amp for now and get a killer sub. You will not regret it.

I'd prioritize a speaker upgrade and go with a receiver. I honestly don't see 7.1 HDMI becoming outdated anytime soon since there isn't even that much 7.1 media out yet. And when it does get outdated a receiver is still less expensive to replace than a pre/pro.

If those are the latest Titan's you have I'd look for five or six more on the used market. IMO 7.1 with room correction benefits greatly from matching speakers. The Titans offer 93 dB sensitivity with one dynamic driver to push which lowers your amplifiers load considerably. Even with the Sony sub you don't need floor standing speakers and all the current they require.

Your choice in a pre/pro is very nice but a balanced speaker system will provide better sound quality for your dollar at this point. With more and more content filling all seven channels I'm not a fan of any linear solid state amp that depends on a small transformer to drive 700-900 watts at theater like levels. My first choice in a receiver would be a used Pioneer SC-05 with an efficient class D amplifier section. My SC-07 simply out classes my previous Integra receiver. System wise the next upgrade would be a real sub like a small Velodyne DD or a JL.

Maybe someone can correct me but I think I found an alright setup.

Amp Emotiva UPA-7 http://emotiva.com/upa7.shtm

Pre/Pro Integra 9.9 http://www.integrahometheater.com/model.cfm?m=DHC-9.9&class=Preamplifier&p=i

Do these work well together? am I missing something obvious? the specs on the Emotiva seem outstanding for the price. whats the catch?

Thank's for everyones help so far.. I'll check back soon.

Thanks for the response. what amp would you suggest? 5.1 channels, I don't believe I need any more than 125 wpc

I notice I can find the intergra DTC 9.8 refurbished or used for around $900. Not sure I can find that local. which Marantz series would you specifically refer too?

I'm trying to keep in mind this is a stepping stone into a complete package years from now.
