my cd rips played from my computer's hard drive sound better than the cds played from the transports.
Sorry that's impossible if the same transport and CD!!!! was used to do the copy with, and both were using the same dac, and exactly the same digital link up to the dac.
George may be correct. I listened to CD s from my computer's transport and then the ripped files that were made from that transport - they sound identical. However, both sound MUCH better than any external transport connected to the same dac. External transport using coax computer USB. Computer software foobar.
