Destat CDS

Cannot speak for the Furutech Destat, I use the Bedini and it works. I've done double blind tests with friends who are far from audiophiles and they confirm improvement. I've simply used two identical CDs, one treated and one not and switched them out randomly.

It is not a placebo effect.

There was a very recent thread on this subject. You might want to do a search. There were those who found it useful and those who heard no difference. Almarg had a very plausible explanation for the different responses to the destat. As for me, I hear no difference.

Celtic, did 2 identical CDs sound the same from the beginning before destat?
Make sure that catalog and UPC numbers match...

I used to use an Audio Revive demagnetizer. I sold it off once I started putting CDs on top of a Schumann resonance device for about 10 seconds before playing. No comparison.

If you check the website of Mapleshade Records or Machina Dynamica then the holistic approach to optimizing CD playback is presented. No single action or gadget does everything, but even one product can make an audible difference. The "jaw dropping" magnitude of benefit most easily heard when a number of ideas are combined.
A bit time consuming to achieve, but rewarding.
