Wood blocks underneath components?? snake oil?

This type of "discussion" comes up a lot with regard to cables as well. Is there a way we could implement a 2 step approach to determine whether the wood blocks are making a difference? For example, could we use a real time analyzer to look at the systems in-room characteristics with an without the wood blocks (or cables, or magic clocks, etc...) in place, then with the wood blocks in place. Obviously you may need to schieve a baseline via averaging repeated measurements, but hyptothetically could we establish whether or not, in room there is any difference, even if it is as minute as "80 hz is always -1db when the wood blocks are in place". If there was any consistent difference proceed to step 2, which would be to determine whether or not the human ear / brain interface is capable of distinguishing between the 2 scanarios.

I have never seen great data on what the human ear can and cannot detect, and I guess it could be different for any 2 individuals. Still I think there are probably some general characteristics regarding hearing that could help determine whether a reported difference is plausible or not.

Mind you I don't know if this is even possible, but I had to ask.

Newbee, the reason I thought of frequency response accross the audible spectrum is that I am not sure how else to quanitfy an audible change at the listening position. I suspect it is this difficulty to quantify that brings everyone back around to DBTs, which I suspect would be hard to set up for resonance control products. Nonetheless I DO use resonance control devices in my own system with my turntable. I think the Walker Resonance Control Discs improve the sound, but I suspect I might go mad trying to find the exact difference with and without.

To Sonfun's point, hockey pucks have been used for this in the past, at much less expense. J10 documented this in Stereophile back in 2001 in his Fine Tunes column. And remember, the NHL cryoes all pucks prior to gametime!
