older CD transport vs newer ones.


I added a fairly inexpensive CD transport to my DCS Rossini DAC/Clock and am shocked how much better it sounds spinning a disc vs streaming it.  It's not even a close call.  I was thinking of bettering my CD transport and was looking at options such at the Jay's CD transport.  There are also options such as Mark Levinson 31.5 which was a 10K unit in it's day.  Any thoughts on the best way to go?  I get a little worried about one of these older units breaking and not being able to get it fixed.

I love my McIntosh MCT 500. Pricey but well built, smooth operating, and great sounding. You also get dsd via built in thumb drive and usb. 
There is something about this that I don't understand.  First off, no one has asked about where the "streaming" is coming from.  I believe the OP when he says that the CD transport sounds better, it is after all his system.  

I don't have a dcs, but I do have a Bryston BDA-3 DAC and it buffers about 30 seconds of digital input so that it can use its internal clock to eliminate jitter.  Does the dcs not have such a feature?

And I'm not trying to say that a better transport won't be better in some circumstances, but this seems like one of those things that has a very quickly reached point of diminishing returns.

Please let me know your thoughts.  Thanks.

Some may feel that way. I believe that the design, engineering,  built construction,  power supply quality and implementation are just as meaningful for a CD transport as any other electronic/audio component
But as I noted above,  for some the transport for whatever reason is viewed as not as important as the DAC.

Some are of the belief that a "decent" CD player or transport is enough to get the job done. In my listening experiences,  the better the CD transport,  the better the sound quality.
