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!

@tweak1 No, my head would not explode when visiting Synergistic Research. If they have more than $1K of instruments in that two garage spot "warehouse" of theirs. If a single cable company ever published a study, I'd buy into their BS. And please don't tell me you can't measure this. I own a laser doppler vibrometer good to 100kHz. I'm sure your ears are more accurate than that. But no matter how many times I've pointed it at a tweeter, no matter what cable, it always shows the same thing when fed same wave. Funny how not one cable company seems to own a device like that. I suspect most of them don't even own a decent multimeter.

Curious the number of persons who want to argue about the merits of cable vs toslink even though the initial poster is using toslink with both transports.  So this is irrelevant. 

That said, the cable crowd seem to think there is only one kind of toslink,  when there is a wide range. Yes a $2.00 toslink may sound worse than a $100.00 cable.  I personally like Wireworld Toslink  which was about $80.00.  
So if fuses are directional, is the wire the fuse connected to directional? It MUST be, right? Are all of the other wires connecting everything else in a component also directional? I doubt that component manufacturers take the directionality of those little and not so little wires and board traces into account, and most of ’em are thicker than the fuse wire...And if all of those little wires and board traces are directional, isn’t the sum of all of it working together resulting in directionality chaos? And if it is, why can things still sound fine? Why? Why? Man...now I need a nap...
Somebody must have taken his smart pill today. Yes, all wire is directional, internal speaker wire, internal electronics wire, speaker wire, digital cable, interconnects, transformer wire, fuses, capacitor wire, all of it. That’s why many high end cable companies have been controlling directionality for 25 years. That’s also why power cords should be controlled for directionality. And why HDMI cables should be controlled for directionality. Note that fuses and cables and cords in AC circuits are directional.

The more wire you can put into the correct direction the better the system will sound. (It’s quite common for audiophiles to believe their system sounds great. Just an observation.) 😬
