I agree with Shinerman. Some CD's do sound better in 5.1. I've noticed that all of Steely Dan's music (either CD's or DTS/DVD-Audio) sounds consistantly well produced. Same with Todd Rundgren, Lyle Lovett and others. Generally, I've found that the new releases recorded in high resolution formats to begin with sound like they are supposed to (even among these there are still major quality differences in channel mixing... deciding where to locate each instrument on the soundstage... depending on the skills and imagination of the mixer). The problems usually occur when a disc has been remastered from a previous recordings. Even on DVD-Audio or SACD, they just don't compare. For example, Marvin Gaye's "Greatest Hits" (DVD-Audio) sounds thin and lifeless on my system no matter what I do to juice it. However, this doesn't have to be the case as Pink Floyd's re-mastered SACD "Dark Side of the Moon" originally recorded in 1967 proves. Many still consider it the best recorded album of all time! That's why I now read music reviews before I buy. I don't read them for the reviewer's musical tastes, but for the recording quality ratings. That bit of info. alone can make the difference between wasting your money or not. No matter HOW much you like a particular piece of music, once you get used to hearing great sounding production it's hard to listen to anything less!
By the way, does anyone think that 7.1 is an improvement over 5.1 for music? I've tried 'em both and I prefer 5.1 (except for movies). It's probably due to the shape of my room, but adding the two side speakers to make 7.1 only muddies the music. In 5.1 my surround side channels feed the two speakers behind me and I'm close to having equal distance from all 5 speakers at the listening position. Because of my room dimensions (15x20 rectangular) there is simply no way to place the sides far enough away to match the ofthers, without tightening up everything to a distance that is absurd. Even my receiver's (Denon 3805) speaker distance compensation doesn't make it any better, and SACDs override it anyway, at least on my Denon 220. Anyone have a success story about 7.1 sounding better then 5.1 for music?
