Good Product or Nonsense?

As I remember, Auric was quite popular among Audiogon members some time ago. I just never got there to try it because cds are not that important to me. I think, most or all who compared said that it was better than Optrics. Some preferred Walker, though, if memory serves.

Never tried it, but Walter Davies of LAST usually or always makes good stuff. But he is analog guy. So is Lloyd Walker.

Back in the late 80's a high end audio shop in Phoenix recommended Armorall on our CD's. Two friends and I did a listening test comparing two different Dire Straits CD's one with and one without Armorall. None of us could believe the difference we heard. And one of us wasn't even consuming beer! If memory serves, the treated CD had better clarity and depth. Has anyone heard of this?

Yeah, but I decided not to try it and got Optrix instead.

Thanks @inna . Might try the Auric. But not into using a Sharpie on my CDs, many of them are collectables.
