I'm in total agreement with this statement. I bought a Sony/dvd/sacd player when they first came out and thought sacd was pretty good. I subsequently switched to a Denon DVD2900 and the sacd performance on this machine is excellent. However I like classical and about 80% of my sacd collection (around 60 titles) is classical.
There are some attempts to change this, Snow Patrol and the new Goldfrapp album are on sacd but the cynic in me thinks may be more for surround sound than actually better 'stereo' sound.
As for DVD-A, which the Denon can do, I have 2 discs really struggle to find anything I like on the format and can't judge the sound quality from the 2 I have. I don't trust these new Dualdisks too many hifi comapnies have issued statements saying 'at you own risk'.
