wow. love the opinions. No BS here! Just as i thought, when looking at receivers for home theater, the THX symbol only meant $$$$ where these standards are met and/or exceeded by receivers that are not certified. Of course being certified will add cost, that little logo costs YOU $$$$. This is a factor in my puchase decision. I was looking at that Boston Accoustics receiver that went from 2999 US to 999 US (at 60 pds???) and thought i could use that power, with rave reviews on the sound quality (im no expert). And Denon doesnt even bother with the THX unless you get to the HIGH end. Of course a 3806 will sound awsome... i just "rented" a Denon 886s from Best Buy... its ok, only 100 wpc, no THX and sounds pretty good, as powerful and clear as the Pioneer 1015tx as far as im concerned, which is Select ceritified... I just want a good receiver with LOTS off clean juice.... screw all the badges... 7.1 channels of pure sound with the basic decoding (DD, DD Ex, DTS, etc.) will be fine.... im still searching!!
