What's wrong with a DVD player as a transport?


Just wondering if there is some technical reason a dvd player won't perform as well as a cd player? Also why would a changer not perform as well as a single disc player? Please answer with technical reasons. Thank You

Jimstew,

Although I do not necessarily agree that a DVD player should be better than a CD player or a CD mega changer or special dedicated DAC, my experience is that the differences between players are small enough that I am not at all surprised to read your comment.

My room, speakers and the source material mix/mastering quality totally dominate the quality of what I achieve in playback from my system. Differences in digital players tend to be dwarfed by these other factors.

If anyone wants to prove this to themselves....simply move your speakers by about two feet and you will immediately hear a significant audible difference, often with one position being decidedly better than another. Or compare an original release with a remastered version. Switching between one CD player and another rarely produces such big differences...
I seem to remember the "measurements" section of a review where John Atkinson discussed DVD players being able to generally read the more difficult test tracks without error, compared to cd players. OTOH, I found this post where he indicated their inferiority due to master clock frequency discrepancies.

With the newer stuff, I have to agree with Avguygeorge regarding quality and implementation as my Muse 10 sounds much better than the PD65 with D2D-1 and DAC 3.0 that it replaced.
I bought a used Reimyo DAP-777 DAC here on the 'Gon and was disappointed with its performance using both an older Pioneer CDP with the Stable Platter Mechanism and a Muse 9 CDP as transport. I bought a demo Sony DVP-S7700 CD/DVD player on eBay for $200, and the sound with the Reimyo is incredible. Talk about 'hearing into' the recording. I could hardly believe that a transport could make such a HUGE difference. And that's the stock Sony. (You can have $1300 of mods done to it if you feel guilty spending so little).
I cannot recommend this transport enough.
The sad truth is that, arguably, the weakest link in most high-end cd-playback system is...the cd itself.
The DVD player I was using was a fully modded
Pioneer DV-563A, by fully modded I mean Power supply R core transformer, pi filter Panasonic caps, and Clock, etc, etc.
I several systems the diferences were obvious, you could tell right away, I even gave it full burn in, with very slight quality increase.

I am not trying to pick a fight or disrespect anyone, I just feel that I was misguided by reviews and modders I and want to tell my story to help somebody else, I spent and lost, money trying to get a better transport with terrible results, I even bought the fully modded Sqeezebox2, which is a great product! , but High End it is not.....yet.
