Any thoughts on the CD "trimmer"

Missti, ask Krell about how I discovered that overhead halogen lights, shining through the Plexiglas lid of their MD10 CD transport effected the bit stream to the D to A converter.

Stray light, bounced light and vibration are all real. The CD player must work harder to get the data correct when it meets these forms of interference. Yes, it still delivers good sound but there IS a difference and that's what most audiophiles are seeking.

So, if a tweak helps a little and the perfectionist can hear it (for instance Essentialaudio), they are availing themselves of better quality and passing along the experience to others that want to get that last bit of music.

If you can't hear it, be happy and don't spend the money.

the black marker technique is not necessarily a good thing. Certainly a difference can be heard when playing a 'blacklined' disc vs. not lined. I didn't believe it either, but I actually tried it before posting opines that it simply cannot work; it does work. However I discovered that the marker technique actually caused changes in the sound that I didn't like, so I removed the marker with alcohol and the sound reverted to its' original state.

Same result for the Auric Illuminator product. It certainly does change the sound, but not necessarily in a good way. I'm glad that the product is also removeable.

You have to remember that the ones/zeros are not digitally encoded, they are contained within an analog modulated carrier envelope which is detected via laser pickup & decoded back into digital. Certainly there are numerous causes of bit error degradation along this circuitous path.

That may be so, Albert, but the fact is that the VAST majority of CD players pull the disc inside the machine's case. So, please explain to me just how "stray" light is getting inside the player?

I'd suggest that all of this theorizing is not helping the original poster. Y'all should read the Audiodesksysteme website to get an accurate idea of what this system does.
A review was published in a British HiFi magazine recently that explains the process also, and the reviewer purchased one.
I have heard discs treated by this system, and it really does work. It does improve the sound, and CDs that sounded nasty/edgy sounded much better after treatment.
