Differences between cd transports?


Howdy,I borrowed a dedicated CD transport (Musical Fidelity) from a friend. I have found that music sounds much better with his transport than with the CD player I’ve been using to spin CDs. In both cases, I am using exactly the same DAC via the optical out connection from the transport and the CD player. So: is there any rational reason that, using the same digital to analog converter, one CD spinner should sound much better than another?Thanks!

Well, finally you said something that makes sense. A wire company that makes wire. Well, shut my mouth and call me corn pone. But we were discussing cable companies, whether they made their own wire or not. Which would make it easier to control directionality of wire. Not that it’s terribly difficult in any case. Another obvious way to control directionality is make some interconnects with the first section of wire off the spool and listen both directions. Then you will know the direction for the entire spool. Or, just skip the whole process of controlling directionality and leave it up to the end user to figure it out. Assuming the end user cares, which he probably doesn’t. That’s what most aftermarket fuse companies do.

Please explain precisely what you mean when you say that audio  wire is "directional." 
George,

I don’t know from where you took this information... Simudio has its own Proprietary CD drive system mounted on gel-based 4-point floating suspension for vibration damping .comparing to the Cambridge CXC the 260T offers much more details , organic and natural sound.


The drive circuit board may be proprietary as is the Cambridge CXC drive circuit board, but it sure looks like it has the Sanyo SF65 laser and mech in it.


SIMAUDIO MOON 260D-PCM1793-Sanyo SF-HD65

Can be ordered with or without dac section

Never found Vassili’s list to be wrong yet.
