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!

atstel, I do not know why you bother. When humans have no idea what is going on they mythologize and they hold their myths dear even if they are patently absurd. If you back them up against a wall they just get nasty. 
Still waiting for asztell’s video. I’m getting a bad feeling. 😛

mystijin, give me a break! 
I heard my friend's new DAC from COS Engineering and it blew away my EAR Acute.  Using a 1998 Pioneer DV-5 DVD player with a dual laser for the spinner, the DAC increased the enjoyment of listening by improved bass, dynamics, soundstage, imaging, resolution without adding negative characteristics.  No tubes.  I (and he) was shocked at the huge difference.  His DAC is a few years old and my EAR Acute is 11 years old.  Maybe separates are better or DACs have greatly improved.
I am looking for a half size CD transport under $1000 to use with my Mytek Brooklyn  DAC. I am moving and the new audio cabinet will be space constrained. I am considering Pro Ject DS2 T or the Nuprime CDT 8 Pro. The Pro Ject appears to have better ergonomics and remote. The Nuprime has the ability to upsample to output different resolutions including DSD. Although the Mytek is able to decode almost any sample rate not sure if there would be any significant audible difference. Both can output AES EBU. I am currently using a Rotel 991 AE through SPDIF which sounds terrifc but I have to give it up.
