audiofan:

I concur with JohnK. I believe you'd have to step up to a power amp in the 200-watt-per-channel range and be in a really huge room--6,000 to 8,000 cu ft--to detect any difference in performance.

With your current setup and room size as well as listening tastes, I'd be surprised if you heard any difference at all. I don't think it's a worthwhile upgrade.
