do burnt CD copys sound as good as originals?


I have several 2nd generation copies of music friends have burned for me & I'm just wondering....(these were burned off a laptop). I just got a burner for my personal computer installed & might make some compilations for roadtrips, etc. thanks for any input or tips...happy holidays & listening.

I have Marantz Professional Cd Recorder/Player. The cd's I have made sound pretty darn great. As for computer burning, don't do it but have had some made via that way and they sound fine.
As it happens a Marantz Pro (model 510 I believe?) was the dual-well machine I referred to in my post of 1/7. Not that it made 'bad' copies by any means, just not as good (digital or analog) as the HHB unit I ultimately bought at the time (meaning less like the original). Differences do exist though sometimes subtle.
I was just reading info on the Memory Player by Nova Physics over at StereoTimes. It appears to me that this new player extracts (rips) music from the CD in a read-till-right fashion (sounds like EAC software) and stores it in flash memory to play it. What I find interesting is that it plays the music from flash memory rather than from the CD. I wonder if by using the solid state flash memory it may avoid further jitter or read/write error issues that are introduced by CDs or even hard drives. Just a thought...
Sounds somewhat like the approach taken by the newer Meridian players just being discussed on another thread.
I strikes me that we will increasing see boxes that use big storage to store multiple cds or worse for non-immediate replay from the cd transport. The question is going to be which affords the best sound. VRS was the first of these that I saw and I have no idea what has happened to them. They were at the 2005 RMAF with a nice overall system and good sound.
