transport sound quality of good modern CDPs


Used to be they made big heavy expensive CD transports that improved the sound out of your DAC over a standard CDP transport section. Very few are made anymore, yet there are plenty of good outboard DACs on the market. The better one-box CDPs can often sound as good as redbook allows, yet most seem to use generic off-the-shelf ho-hum transport mechanics with maybe a little tweaking to the servo circuitry. So my question is two-fold:

1) Have the lightweight seemingly modest transports in excellent sounding $2-4K CDPs gotten good enough that their mfgs feel their sound can't be significantly improved by using a near-industrial-grade transport?

2) Would there be a notable sound difference by running the digital output of say a Musical Fidelity A308 CDP into a $5K outboard DAC vs running a Levinson No 37 transport into the same DAC? Or for that matter, a Rega Planet or NAD C541i?

The lack of decent quality CD transports today amazed me as well until I started auditioning a number of transports from a number of manufacturers (Theta, EAD, Audio Alchemy, and Wadia) and discovered only nominal differences between them. These were used with a number of different DAC's (MSB, Wadia, and Bel Canto) and still I found no differences that would merit spending substantially more for one compared with the others. The differences between the DAC's was much easier to appreciate. Currently I use a Panasonic RP-91 DVD-A player with a Wadia 25 DAC in my reference stereo rig and it sounds great. Incidently, I also found no significant differences between the coaxial, balanced, and ST optical outputs in any of the configurations I tried. Off hand, I would just use the best reasonably priced DVD player available as a transport and invest the difference in program material or other components. Best of luck!
Great question. Yes, I compared the mentioned transports to the Panasonic RP-91 which is the primary reason that I currently employ it in a mostly-music stereo system. As I wrote before, there really was very little difference between any of them. To be honest I couldn't even develop a real preference among the transports I auditioned. Perhaps this is why not many dedicated CD transports are being manufactured anymore while at the same time the stereo DAC market remains quite active.
