Marigo Labs Signature 3-D stabilizer.

On a whim, I purchased one of these devices. I didn't want to like it since loading CD's, SACD's and DVD's into my VSEI Level 5 modified Sony DVD-S9000ES is now more complicated but....it does work, confound it! At first, I thought it was stripping some of the presence or air from the music and making it somewhat homogenous. Many comparisons later, I've concluded that it does improve the sound across the board. On some recordings of the human voice, particularly female, it reduces amusical sibilance and shrillness in the upper registers. Overall, it imparts a more believable presentation to what is, after all, artificially reproduced music. As to why it works, I have no idea except to say that electromechanical systems have many subtle variables that are hard to define by measurement or theory.

Gfroman,
You stated that you believe the Marigo is the best digital cable in the world. I'm using the Apparition 5.7 balanced cable in my system and agree that it is an excellent cable, maybe even one of the best. However, I'm not prepared to state that it is the best digital cable in the world. This implies that I've listened to every digital cable available. And while that may be interesting (and probably illuminating as well) it would be close to impossible.

I see yours is up for sale. Have you found something better?

Tab110s,
I'm giving the Stealth Varidig Sextet a shot.

I just bought one of the Marigo 3D Signature mats after hearing all of the raves. I'm sorry but I think it's garbage. Both me and a friend listened to music with and without the mat. The difference is so incredibly subtle that it is very difficult to hear any difference other than the mat washes out the body in the notes. We listened to different CD's for an hour. Then after listening to 10 second stretches of music, back to back with and without mat, these are my conclusions:
The mat washes the music taking out body. The overtones, which are very important in music, seem to have vanished. For example, on my system you can hear the guitar body vibrate the overtones, which produces a nice round image in the notes. You can tell what type of guitar it is and how the string was plucked. With the mat this is diminished, giving the music a flat presentation.
This mat seems to do the opposite to what it claims. Although I must admit, it's subtle, but it's noticeable if I listen for it.

I just upgraded the tubes in my preamp to tungsol (for $35) which made a phenominal difference. This mat at $200 is not worth it.

Consider the psychology of this: You just spent $200 on a tweak. You don't want to be cheated and you certainly don't want to look stupid, so you convince yourself that it works. You create the illusion that it works and you become convinced. You don't believe me? Ask any quantum physicist or even a psychologist. We do this subconsciously all of the time. We live in a subjective world.

If you're wondering, my system is all less than 6 monthes old comprising a Jolida 1501RC amp, Music hall CD25.2 player, Musical Fidelity tube buffer, Quad 21L speakers, upgraded power cords, Mapleshade power strip, Quantum EMI reorganizer, and soft annealed silver interconnects with Eichman connectors (Guerrilla audio).
