Yeah, don't bother.I've already got a set of speakers (Tannoys) which sound great consisting of a sub and two satellite fronts. What I'm looking for is a similar set up to the Denon s101/301 where Denon claim that they get 5:1 sound from 3 speakers, but they come with a DVD which I don't need. I'm aware of the Yamaha DSP gear but don't like the look of it.
But will suffer from 3 to 6dB of Dolby Digital 5.1 to 2.1/2.0 downmix compression, limiting dynamic range AND will be missing the LFE altogether as this is NOT down mixed to the main front left & right speakers. Clarity won't be affected but drama will. This will be the result of running any AV setup without a center speaker and/or sub. For movies, it's stereo setups that do the 'mashing'....which will probably have better sounding front channels than any equivalently priced mashed up AV kit.
