The only downsides of more basic two-channel is, once you get it right, your done, and the only remaining and most persistent hurdle is recording quality differences. By "done," I mean, no more fixing anything or shopping for upgrades. Great, if the music itself is actually the end goal, perhaps not so, if system building and tweaking is. The other, being, that it doesn't leave much to talk about on audio forums. I mean, look how many new products you reviewers have to go thru just to keep this channel moving. Y'all need as many channels, new effects and speakers to talk about as you can get.
