I decided to stop messing around and put my favorite album in (after using Duran Duran's Greatest CD as a warmup... inconclusive results there due to low volume):
The thing you have to know is that the SACD layer of Roxy Music's Avalon is a different mix. It took me about a third of the album to realize that... at first I was just, like, whoa, blown away. Bryan Ferry's voice sounds clearer, the familiar instruments are better separated, drums are more impactful, and there is even a sense of vertical space added. I've listened to this album over a hundred times, but only on the Red Book layer. If you're only familiar with the CD or the vinyl versions, it's going to be an odd experience. It's exactly the same album, but everything is a little different. Wikipedia claims the stereo mix is identical, but I am telling you that it is not. I wasn't expecting much from my cheap Sony player, but this session told me that I've been missing a lot on my hybrid SACD discs.
I thought that it was a downmix of the surround version, but if Wikipedia says the stereo mix is identical to the original, then the difference must come solely from the SACD encoding. I don't actually believe that, though, because many of the stereo elements sound like they are placed differently (and each voice or instrument fades in or out more distinctly, like Andy Mckay's distinctive oboe)... perhaps the UHP-H1 is ignoring the stereo mix and downmixing the surround mix anyway. The principal impressions I got from the SACD layer are clarity and separation. Voices and instruments that are mixed together in the original version seem to be pulled apart and they are more clearly defined... the effect is not that subtle. Once again, it's more theatrical, like a concert performance. I'm not entirely sure if I like it, since I'm so familiar with the original mix. I'll have to listen to it a few more times, especially on my headphones.
If you have this SACD, I strongly recommend flipping between the layers if your player allows you. It's a bit like getting two albums for the price of one. This album is probably even more fun with a 5.1 surround system. I'm not usually one for gimmickry, but this was fun. I'm hoping the next few SACDs are as entertaining as this one.
