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!

Sir.... You obviously do not have a clue about.... well, much of anything....  that pertains to electronics, physics.... i.e. the stuff that pertains to this issue of "directionality."

Enough.... You truly are a charlatan.
Gosh, are all philosophers of science so adept at name calling? What is this, the revenge of the nerds?
My SR fuses are absolutely directional.  As to most of my cabling, it becomes directional with use, with ICs marked on one end so that it is always inserted in the same direction.  

As to CD transports, I guess I'm lazy and prefer my one piece EAR Acute player with upgraded NOS tubes and superior cabling.  It sounds analog like, great bass, dynamic range and smooth highs.  The mids sound just like a good  LP.

I've always heard that the superior transports extract more information off he CD.  Until I have a split system of transport and DAC, I won't know how much better CDs can sound.  
Yes I agree pure CD transport and a good DAC
extract more information off he CD since I upgraded my transport to Sim 260T and McIntosh DAC I don't miss my vinyl collection anymore and I don't hear any difference between CD's to hi-res music files.
Heard an older model Sim CDP that we used as a transport.  We compared the SIM to the Rega though a DHT tube DAC and a highly modified Musical Fidelity DAC.  The Rega sounded a lot better in many ways to the older SIM.  Go figure.  Happy Listening.
