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!

I wish this forum would allow pictures. Cleaning up the basement collection this weekend. I have multiple spools of speaker cables, canard microphone cables, etc. I also own quite a bit of measuring equipment. I just tested a spool of Canare L4es6 cable. About 250ft left on the spool. Same resistance in both directions to 5 digits. Must be them crafty Japanese. Oh and Canare actually does make their own wire.
I don’t believe you. How about them apples? 🍎 🍎 🍎 Even a tiny fuse wire 3/4” long measures slightly different resistance each way. 🔚 🔜

So, you found one cable company that makes its own wire. Big deal. If I even believe that, which I actually don’t.
@geoffkait Canare makes wire, that's what they sell. They are not a cable company.
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.
geoffkait:
Please explain precisely what you mean when you say that audio  wire is "directional."
