Herbie's Grungebuster 2 CD Mat vs Marigo's 3-D Sig

I owned one of Herbies. Never had the other. Herbies made a significant improvement. Only prob I had with it was because of its small size, it either stuck to a cd that I put away or fell off into the player. Either way, I LOST it! (I think I'll buy another one though).

Never used the Herbie but have the signature Marigo and have used the standard. Put it this way, I do not listen to cds without it. Best way I can describe it is more detailed but smooth. If you can't afford the signature the std is a huge imporvement from using nothing.

Hmmmm, so far it sounds like thumbs up to both products. Tarsando and Rello: Thanks for the info.

I haven't used either the Grungebuster 2 or the Signature Marigo Mat, but I have used both Shinola and Auric Illuminator 2. This topic is confusing to me, and these CD treatment products seem surprisingly difficult to evaluate.

Anybody else have impressions?
