Can somebody techie pleez explain why a £200 CD deck is better than a £900 DVD player at CD replay? What are the compromises forced by DVD playback? Is it in the transport, the dacs, or what? We see some decks from Tag and Arcam that claim to be able to do the job. Why and how? Also, I always assumed that DVD-A was a relative of DVD and SACD a relative of CD but now I hear that SACD is in fact, similar to DVD. Does this mean that a SACD/ CD player will also not be as good as a dedicated CD player? I'm thinking about the new Pioneer 757i but apparently it's flat for CD's, as is my Sony DVPNS700. I'm planning to add an Arcam CD player in future and use the Pioneer for SACD/DVD/DVD-A/DTS. I'm also aware that Marantz do an SA-12 (or something) that's also an all in one but much more expensive. Anyone know how this thing comapares to say, a £1000 CD player for CD playback? I would really like it all in one box but it don't look like I can have it. Any ideas?
