Would treated CD's or OOP's-hold its value later?

Nevillekapadia-

I've tried all of the CD tweaks you mention. IMO, they produce the greatest improvement with poor sounding CDs.

You have a very revealing system, you should check out the link below if you're interested in improving Redbook CD playback:

Nevillekapadia, I know what you mean.. I tend to make copies of my most loved records, not all I listen to since that would take forever as you suggest. :) I basically listen to the originals first, if it turns out I really like them I take the trouble to make a copy and then I can start tweaking the copy. It's good fun, and doesn't take too much time.

Enjoy the music!

Kana, you are so right with tweaks on poor soinding CD's. We did the same tweak on the Police SACD and it did lift up the level of red book just short of the SACD quality, but did not have much effect on the SACD layer.
Tweaks do change the sound, one has to decide if the change is more correct in an overall perspective.
My main concern is that I don't sacrifice my Out of print CD's for the sake of sonics.
As Osgorth suggested to play around with a burnt copy, would be ideal.
With the nova physics I feel that the hard drive would eventually be the way to go. Initial trials with other audiophile colleagues seem very promising, and detail can be comparable to top end sources and in some respects could even better on red book.
Always a never ending process!
Thanks once again for your inputs as it makes the thread even more informative.
