Anyone use CD tweaks

Another vote for Shine-Ola. I use it and definitely hear improvements. The sound if often more open, transparent and detailed.

On some CD's the improvements are significant. On other CD's it is subtle.

I think that the improvements are more obvious as your system becomes more revealing.

I am using optrix cleaner mainly for that,notice some clarity improvement.I also use rd3 after cleaning though too.The combo seems to offer a nice clarity improvement to my ears.

I use walker Vivid and Olde English Polish and they both yield the effects Tvad described:
"louder, more open and with better dynamics"
I can no longer find satisfaction with untreated disks.

Also, freezing seems to be the most effective even though the description(s) of why it works make no sense to me. Its one of those things that shouldn't work, but does.

Yes, the Shine-Ola product does a wonderful job for me on my cd's. It's simple and has better results than other products I've tried . Such a simple means, to a satisfying result!
