Re: Your opinions are contrary to scientific evidence

Yep I've compared them many times and there's quite a difference. It obviously depends on the equipment involved, experience and what's important to you when you listen.

Yep I know a little about DSD and I question you characterization that there are noise artifacts, there is more noise up where we can't hear well: There is more noise above 22.05KHz but there is signal there too and in the best of circumstances Redbook doesn't have anything there, signal or noise, in less than ideal cases there is aliasing there. Below 20kHz SACD has a noise floor about 24dB lower than redbook. (Depending on your player obviously, but no Redbook player or SACD player can do better than the format allows.)

Looking at it a little more simply, SACD has about four times as much info available than redbook, so it's no surprise that it can sound better.

Actually after listening to SACD for a while on my old equipment there was pain in my (and my daughter's) ears when we went back to Redbook. BUT SACD showed us how much better things could sound so we improved the system over all and the "pain of Redbook" went away. Now it's just an annoyance :)

If DSD is counterintuitive, perhaps a little more exposure will fix it and you'll see that the filters in PCM and their effects are actually the more counterintuitive. If they were that intuitive people would be able to implement them more reliably and there would be less arguing about the sampling theorem and also less arguing about no output filter DACs vs. slow roll off filters vs. oversampling, etc.
