What is purpose of a cd transport?

Audio Logic has done the same thing with their DAC in the past (the new MDX version is a one-box DAC)--in fact, their prototype actually had three boxes, one for the DAC circuitry, one for the analog power supply and one for the digital power supply. With my Forsell's air pump, I have four boxes instead of one. My non-audiophile friends roll their eyes a lot. Does it all make a difference? I think so, but in objective terms the difference all of my esoterica makes is probably very little in the grand scheme of playing music, otherwise I could not be moved listening to music on my car radio.

Yeah Rcprince 4 boxes !!!
In the Blue Circle product I mentioned (BC501-OB), the separate power supply while in one box is actually two supplies. There are two umbilical cords between the power supply and the DAC, one the digital supply, the other analog.

That's how the production Audio Logic with the single power supply did it as well. A good design. I sort of miss the separate boxes from the prototype, though, because you could turn off the analog stage (and therefore save tube life) while leaving the digital stage on all the time, which seemed to help it sound better.

Hell, Sugarbrie, my PREAMP is 4 boxes. Where my friends can turn on their receiver with one button and a CD player with another and have music, I have a tuner, a CD transport, a DAC, two preamp power supplies, an active crossover and four amplifiers to turn on to get music (and then I have to wait 6 minutes until the Jadis' auto-muting goes off)! Is it any wonder people view us as "different"?

I love, I love it, Rcprince !!!!

If you listen to vinyl then you have to get the Blue Circle BC27pi phono stage, even if only for the reason it's a two box phono stage !!

Do you have separate mono-block amps ??
6 separate cables for each tri-wire speaker?

Then install dedicated AC power lines for each power cord !!

Sorry, I am getting out of control here...

The purpose is to transmit digital data to the DA convertor for processing.

A good cd transport definitely make a difference as compared to an average one.

Of course, you can said that a CD transport with a DAC will definitely beat a 1 box player provided that u are comparing in the same class which will cost more.

My advise is still keep to a 1 box player. A CD transport with a DAC sill required a good interconnect & power cable matching in order to sound good.

Sometimes, making thing complicated is a long way to achieve good sound. Keeping your stuff as simple ( CD player, int. amp & speaker ) as it is will be more easier for u to achieve a good sound unless u don't mind spending $$$.
