I'm interested in finding out whether relatively inexpensive dvds, especially universal players (such as the pioneer 565 or 656), can operate effectively as cd transports when the digital output is used?
Is it worth using dvd players in this way, compared with the transports on a dedicated cd player? And are there any specific makes which are known for their quality of dvd transports, eg. denon, H/K?
The Pioneers are very well built and long lasting players and so is the Yamaha DVD-S540, they can play difficult discs and make excellent transport and are priced really nice.

I believe that all the players mentioned above will play great for there money, but if you plane on listening to cd’s and not dvd’s its better that you get a good cd player or a cd transport that will have a really better digital signal than a dvd player..

I have some CDs that won't play or skips badly on my Yamaha CDX1000 CD-only player but will play flawlessly on an ordinary generic DVD player. *I have read that the DVD player's optical reader has a finer laser beam than do CD players. *Does this account for my experience? Are DVD player's better at extracting the digital bits than CD players?

Audioholic : Why would "a good cd player or a cd transport" have "a really better digital signal than a dvd player?" It's easy to show that the digital data read from a CD using a CD player will be identical to the digital data read from a CD using a DVD player (assuming competent design in both players and media that is not damaged or defective). In what way is the identical data "better" when ready by the CD player?

Reading a CD or a DVD is simply read numeric data. The price has no bearing on the data read.
The only important part is the DAC. This is the reason why some of the high end audio CD player were having a separate box for the DAC part (upgradable for mucho dineros por favor).
Considering that all of this is electronic, we can apply the Moore rule: every 18 month you get double for the same price. What could you get for 500$ in June 2002? Now you can get better for 250$
BTW, the term transport does not seem to apply to the DAC part. I always thought that transport was the part moving and reading the CD/DVD signal (which is very cheap). Can any one explain?

Pam, you're right. *What gave you the impression that it might be otherwise?
One would generally think that this would be true.
In the past I have had the chance to look at some of the SPDIF 75 ohm drive outputs of CD players and some of the DVD units. I have not exactly been impressed as to how well the the drive will comply with a 75 ohm impedance over the bandwidth required. Or to put it another way; this is not the place I would use a pulse transformer. The real shame of this is that good high speed video op amps are not exactly rare or expensive, and I don't understand why they are not used.
If GDS has schematics of some of the contemporary units I would be interested in his comments.
