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!

yes this should end, but if, as you said, that the ac in cables is minimal, then shouldn't it running as you said back and forth be minimal, too? 

AND, what about optic cables

Hopefully someone else with electrical knowledge in audio component and cable signal will agree with you, and put a bow on it, as it seems only the two of us are discussing this, and Im not convinced
Be careful what you wish for. Besides, aerospace engineers trump electronics engineers.

Take the case for two wires connected to a speaker, + and -. When the current travels toward the speaker on one wire it travels the opposite direction on the other wire. And vice versa.


You have no idea what you are talking about. How do you think the woofer moves back? Which way do the electrons "flow" then? Take a quick look at a audio wave. Ever noticed it has a negative side? It's called AC for a reason. Ever heard of balanced amplifiers: there is no ground.

You can't have it both ways. The current either flows both ways without which cable capacitance wouldn't exist, another one of your major concerns. This is 7th grade physics for those of us that actually went to school.

>>>>>First of all electrons don’t flow. In an AC circuit electrons are essentially at a standstill. You’re not even warm yet. Nice to see you went to 7th grade. How about 8th grade? Current flow through both + and - speaker terminals. It alternates. That’s why if you reverse the + and - cables the speakers will still play music but Polarity is Reverse from what they were before you reversed + and -. There is no ground. Duh!
