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!

When corrected that ICs are not driven by DC within the preamp/dac/amp, but are instead AC signals:

... if that’s true why aren’t people getting the crap shocked out of them when they change ICs or speaker cables with music playing?
Because an IC or speaker cable’s AC audio signal is very low current.

so, you're saying low current ac negates directional flow of signal?
This thread is: "Differences between cd transports?" You seem to be drifting off-topic.

I was merely correcting you that audio signals in an IC or speaker cable are not "driven by DC within the preamp/dac/amp," as you had claimed.
