Audio desk CD Sound Improver

I "had" the unit and was not impressed. I have a good friend on Audiogon that swears by it. I just thought it was to easy to screw up a good CD. The few that I did, I could not hear any difference one way or the other. I happen to have 2 of the same CD so to me this was a very good A/B.

IPY,
As the manufacturers site puts it,you only really notice a difference on high end gear.However I have cut a few for friends with lower priced gear and they also like what it does a lot. It makes a huge difference in marginally produced recordings.Tames the frizzies and harsh transients especially on older recordings.
Takes one minute or less ,like balancing a tire, tracks down the road better without having to correct the laser or wheel all the time.
I recommend it .

For about the same price you should look at Reality Check CDR duplication deck, improved sound in CDR and preserves the original CD with no damage........read the large Reality Check thread in progress here.

The "golden rule" of tweaking is never apply a tweak to audio equipment or CD collection that cannot be removed if needed.

The purpose of the Audiodesk Systeme CD Sound Improver is not so much to reduce eccentricity but rather to change the way light reflects and refracts at the edge of the CD by cutting at an angle. It has had a positive effect on every disc I've tried, some more than others but always noticeable, so I don't see a need for its use to be reversible. The effects include greater depth of image and generally cleaner sound. The effects of CD cleaning or treatment fluids also can be observed and are somewhat different as well. The Reality Check duplicator is another technology and approach to improving digital playback and accomplishes its goals. All of the above may be viewed as effective in different aspects and for different reasons. It is pointless to speculate about their effects without hearing them.
