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 I honestly don't see 7.1 HDMI becoming outdated anytime soon since there isn't even that much 7.1 media out yet. And when it does get outdated a receiver is still less expensive to replace than a pre/pro.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