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 can think of three components that vary from transport to transport:

1. Error correction…the better transports can better correct things like scratches, pinholes and other defects.

2.  Jitter.  The better transports will significantly lower the amount of jitter.

3.  Noise.  The better the transport, the less noise that gets output along with the 1s and 0s.  This includes both noise generated by the transport itself, and any induced noises by external vibrations.

have I neglected any other factor on how their sound might differ?
