Guys, I just joined this site 2 days ago while I was searching for HTiB reviews......... I have taken the demo for all the Onkyo models (including the THX certified one), Yamaha YHT-196, Denon 1312xp and Pioneer HTP-071,,,,,, Let me share my thoughts/reviews on these models.
Starting with the Onkyo 3400/3500, its good (or rather good enough) for movies/games but the music quality is terrible to be honest (maybe with proper caliberation it might be good)..... The bass response is pathetic(average or below average).
The Onkyo 5500 was very good (maybe because of 7.1 config), but still lacking in music department.
Ofcourse the THX certified one had to be good but damn expensive around 90K
Yamaha YHT-196 is much better choice than Onkyo 3400/3500, Although it doesn't do HD decoding, but you can still manage it since PS3/ bluray players already have these HD decoders (default) these days. The best part of this model is the Yamaha receiver has a Pre-amp out for connecting an active subwoofer (future upgrade) while the Onkyo 3400/3500 lack this option. Also the subwoofer that comes within the package is better than 3400/3500.
Pioneer HTP-071 is PATHETIC, First I thought the Demo guy forgot to connect the Subwoofer as I couldn't hear any Bass reproduction at all. The other speakers are fine. However if you can upgrade the subwoofer then its good enough. You can upgrade to Active sub as there is a pre-amp out.
Lastly Denon 1312xp IS THE BEST CHOICE AMONG ALL THESE ENTRY LEVEL HTIB. Really good sound quality, both for Music and Movies/Games. If you have to choose then blindly go for this. In fact I didnt feel anything that was needed to upgrade here. I thought it was perfect in its price range.
