Liquid CD treatments?

What is your setup?
Many systems with digital front ends sound as good or better than high end analog these days, but there are many factors that contribute to the overall sound. Every little thing seems to matter.

As for CD treaments, Shine Ola is highly regarded as actually reducing read errors and enancing sound.

Having tried a few of these treatments it is safe to say they are definitely for real.
I also use the Marigo Lab 3-D Signature CD mat routinely, although a cheaper way is to use Herbie's Grungebuster CD mat(s), to give you confidence in the ability of a tweak to instantly upgrade the listening experience.
Newer versions of liquid CD treatments are released even before one can use up container contents of an earlier version. One of the classic liquids in this category is the new and improved Auric Illuminator, and there is no question that it enhances the CD experience. You can initially try one "well reviewed" product, but don't expect unanimity from our diverse Audiogon membership on which is the only one to try first.

Thanks for the responses. My system is Musical Fidelity 3.2 cd player, MF 3.2 integrated, Paradigm studio 100's, VPI Jr. with grado cartridge, and Nordost Red Dawn ic's ,Blu Heaven biwire.

I've done the following:
Listened sequentially to the same CD as follows:
1) With no treatment, for the "baseline"
2) Then, after Shinola-->no discernible difference
3) Then same disc, after Auric Illuminator 2 AND the black marker on the edges and center as directed-->Subtle but definite improvement

HOWEVER, somebody claims to have a friend who tested Auric Illuminator on a "BLER" detector machine, or something like that, and that it INCREASED BLER, whereas the Shinola didn't (and I think he said Shinola decreased BLER).

So that's contradictory to the above "test" I ran. MAYBE, the black marker treatment in the Auric Illuminator kit helps, but the clear gooey stuff to coat the CD hurts, but who knows? I never tested with JUST the black marker treatment, so as far as I'm concerned......

it's still all a BLER to me.

Dred-

Nice setup. Couple thoughts FWIW.
I have an MF A300 integrated which I liked very much.
I had it modded and much of the electronic glare was removed and the noise floor was reduced dramatically.
The reason I state this is that the front end is certainly critical (I had that modded too), but so are the other electronics downstream.
I am a big believer in modding front ends and pre/power for better performance.
Redbook can be great, but like a good LP system (such as you have) it takes some work.
