Tabl10s questions why I have my amp sitting on a combo of Aurios, sorbothane and BDR pucks on bricks.
That picture (in my system listing) was taken previous to my latest tweaks. The amp's four outboard legs now sit on 2 Aurios Pro Max (rear legs) and 2 Finite Elemente Cerapucs (front legs), these sit on the amp platform, the platform's spikes sit on 4 Aurios Pro Max, these sit on about 70lbs of brick. The reasoning and listening tests that went into this:
My system is situated on suspended flooring, any and all equipment stands spiked directly to this floor create an overly resonant sound, mushy bass, smeared and confused mids and highs, squashed macro and micro dynamics. I now have most of my system (exception of amp and tt setup[on wall shelves]) on a large concrete platform that weighs, probably, 400-500lbs (was a fireplace threshold), this has markedly improved the sound. Much more articulation throughout frequency spectrum, greater spaciousness, air, increased detail, transparency, and macro and micro dynamics. The amp, due to space constraints has to go on a seperate brick platform, thus only about 70 lbs of cement. This has the exact same sonic benefits for the amp. Eventually, I will get a larger, heavier concrete pad for the amp as well, expect more of the same benefits listed above.
As for the Aurios/Finite Elemente combo. I've found these add another level of the sonic benefits listed above, spiking directly to concrete and/or using other isolation devices dampens the sound to some degree. The only reason I have the two Cerapucs, is that the Aurios come in sets of three, I now have two sets, I need eight individual Aurios. I've been slowly introducing these in order to determine sonic benefits, another set is on the way as we speak. Eventually, I will be trying the Aurios under the other three racks in my system (between the bottom spikes and concrete slab), I expect the same sonic benefits here.
