what is the theory behind maple stands and racks?

Guido,

Here are the maple platforms.

Actually, the maple platforms themselves are reasonable, it is the brass feet that run up the price.

For example, their 4" platforms with large brass feet are $505/pair. The retail of the brass feet separately are 8 ea at $35 = $280 so that means the two platforms are $225 total which is not bad taking into consideration the finishing and labor.

I was thinking of doing a custom setup with 3 feet, but the third would be a bolt through megafoot. Each megafoot retails for like $110 each.

Well, I could not resist, I went ahead and ordered TerraStone platforms for my speakers. There was a good case for the TS over the maple and the TS was actually more cost effective and instead of raising my towers up 5.5", the TS platforms will only be 1.5" high (1" platform and 0.5" brass radiused feet)

And the black looks nice too :)

Hi Photonman.... Could you give us more info about the particular Terrastone platforms you have ordered.... Size and price.... What is your hypothesis about sonic advantages over 4 inch maple? And of course, let us know actual results once you install them.

Saluti, Guido

I ordered 12" x 16" x 1" for my speakers with a 8" x 13.5" footprint, with three 0.5" radiused brass footers. $534 + shipping. About 3 weeks for delivery for custom order. Paraphrasing my received responses to my questions:

The grain structure of hardwood makes it resonant. This means sympathetic vibration at one or more frequencies within the audible spectrum. The resulting reinforcement can be benign, with a boost in the midrange.

Often this is experienced as non-problematic, or even welcome at first. Less resolving or coherent systems may sound, initially, more musical for the artificial bump in midrange fullness or warmth. But longer listening reveals the effect for what it is: coloration, inaccuracy. Where accessories and furniture are concerned, the ideal is to avoid internal resonant frequencies which result in distortion or coloration. Maple stands WILL color the sound, or even, in some cases (inferior-grade hardwood or that which is incompletely and inconsistently dried) contribute uniquely audible distortion. Also, wood is subject to environmental conditions such as humidity pressure and temperature which can also add to the effect.

TS is some "space age" polymer claimed to be more neutral and will not color reproduced sound. TS is non-porous and inert. It is completely stable and cannot absorb moisture, therefore no warping, cracking, etc. Complete dimensional stability. It does its work of dissipating mechanical energy without adding any evidence of its presence. And the TS platform can be lower than the recommended Maple 4" thickness keeping my drivers at the approximate same height.

The maple platforms would be almost twice the price.

Thank you Photonman.... Keep us posted with your results once you install the new platforms! Guido
