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!

Geoff, you should know by now, this pseudo physics guy will NEVER admit he's wrong

If these negative nellies (who have NEVER tried your products) ever visited Synergistic Research, their heads would explode 
Thanks for your concern but I’m pretty sure I can handle it. Besides, I haven’t had this much free advertising in months. 
Another thread hijacked by GK who, as always, veers any technical audio discussion in absurd directions.  Others have made astute points about the question raised by the OP which I appreciate and can learn from.  My best is advice is to pay him no mind.  
I think, if like 2 yrs ago at RMAF when Geoff beamed himself down to Earth that weekend. He may even do that this year at the new place. So you may not  have to get a ticket to space to go see him.
