Sistrum or Neuance or...?

Geoffkait, I have a Dennensen air suspension platform for my DD turntable and can see your point in lowering the resonant frequency w/ springs. That's what the platform works. I also used to live one block from railroad tracks and it was pretty bad how the entire house rattled when those cargo trains would pass. Those vibrations were coming up 'from the earth', so I don't see a rack like the Sistrum being able to 'drain them back'.

Are you implying that vibrations cannot be "drained to earth" as Sistrum claims?

Psychicanimal - I did not mean to imply that. Anything not "properly isolated" from structural vibration (seismic, trains, traffic, etc.) will certainly move, such as the entire house, as you pointed out. I tend to focus on the frequencies of vibration in range 0-10 Hz, as I think this is where the real problem is (for audio).

Dissmissing Sean's posts as "petty" (Budrew) and mere "ridicule" (Sistrum) is a shame since he built up a case that is at least worthy of some technical explanation. Unlike some others, I think knowing how device works gives an audiophile more control and power than simply trying the device and "seeing" how it does. A "gracious" return policy is not enough for me to trial-to-buy.

I can empathize why Sistrum may not want to get in to it, but that is taking the lower road, especially considering other manufacturers have responded to these types of debates with their design reasoning. Adding a little salt to their non-answer is that Sistrum has repeatedly advertised in these forums. I personally am left with a hole in Sistrum's logic (calling is pointless) and a lesson to become more self-sufficient in audio. Thanks Sean and Joe Ciulla.

Ouch! Sistrum does it again. TWL, better go after the *mature* waitresses full time! I just had my breakfast (that's right--at 2:30 PM!) at the local diner. I mean, they might be *mature*, but all that walking back and forth keeps them in shape! Some dental work might be needed.

Ohlala, ask member Jahaira ( José García ) for a picture of his DIY rack. Well thought out, with shelves that can be tuned for each separate component. It's the real deal.

You see, Sean can't be fooled since on top of all his knowledge and experience he's got a Moca wood board I gave him. He knows what the real deal is...Moca is about as perfect as it gets.

Wow! I don't know how I missed this thread. Sean, FWIW, I think your have covered the matter well. What I don't understand is, instead of a money back guarantee, why don't they send these devises out to the reviewers/labs for some independent (hopefully) reviews to see if professionals can identify the extra benefits they allegedly possess? If they are found to be worth while they will move their product - if not, oh well. Somehow I doubt that this will happen - probably too expensive and unreliable. But other serious manufacturers do that, wonder what the difference may be. Or have I just missed the reviews?
