My favorite was the original Sony HW50ES who was replaced by the IFA 2013 with the HW55ES. The dealer I looked at the HW55ES - and I would have bought the ... If, yes if I had had the best home theater room. Optimal?
1. Since the darkened walls with Molton, ceiling and floor were maintained with high floor in dark. Everything to swallow the remaining light. I have not. For me, it is only the living room situation, moreover, with light flowing floor. While it can darken the room with shutters - but remain light reflections.
2. In the optimal space cables can be routed to the HDMI signal to be transmitted to the projector. Here the Espon running radio-HDMI and without jerking in the best quality.
3. The Epson has, unlike the Sony wireless glasses. In real home theater room you could still create a infrared transmitter forward. But in the living room so you only have the big screen as a reflector. And then I noticed during testing that there may be times disconnections quickly.
Who has a home theater room and perferkten cable laying does not interfere, which should pick up the Sony. All others I recommend Epson.
Ultimately, I bought the Epson EH-TW9200W for 2,500 euros. Since I had to slam. In TV mode during the day it is just a tad bit brighter than the Sony. And through the white housing (as in Sony also) absolutely Living Tough. He incidentally interframe calculation, as well as Sony, which makes watching the pleasant since the 92er generation.
