Back from the demo. I compared Sony HW55 and Epson 9200W on a Draper ReAct screen.
I was astounded by the crystal clear blu ray and HD channel quality, and a perfectly watchable SD (including Gold, which I think can struggle with decent SD images)! I can easily see using a projector exclusively for all TV viewing.
Epson is a bit brighter, and struggles with blacks and motion. Sony was superb in both these departments! I did not test JVC as it isn't bright enough for TV viewing in a bright room. And I did not test 3D.
I'm more or less decided on the Sony, the HW40 which on paper, will offer similar performance as the HW55 at a much lower price. I don't see much sense in spending more than that, with 4K round the corner (that's what I would recommend to Duaplex as well).
Have some practical issues though. Where will the centre speaker go (as the projector screen will be installed above the fireplace)? ReAct isn't acoustically transparent. Draper does make an acoustically transparent version, but that's 3 times the cost.
What about ceiling speakers for centre? Anyone tried it?
