RE: Sheesham / Indian Rosewood Platform

The board is a striking looking ...

It sure is!

... and rather dense two-tone wood from India called Sheesham or Indian Rosewood.

I wonder if this is the same "Indian Rosewood" that is so commonly (if not expensively) used for acoustic guitar backs and sides?

... there's plenty of room to place a set of footers both above and below the platform. And as to this, it makes substantial difference when carefully-considered footers are used with the board.

I had to diagram this out on a piece of paper! Is this correct (minus the adhesive)?

Inverted BDR cones
Carbon fiber discs
Sheesham platform
Carbon fiber discs
Anti-skid pads
MDF shelf

I note that you're using three disc/inverted-cone footers under your pre-amp, and four discs under the platform.

After the proverbial knuckle-test, which produced a quite musical tonality with a strong initial attack and subtle level of sustain, I knew it was a keeper ...

This seems to represent a very different approach than "the-deader-the-better" approach of seeking out really dense and inert shelf and platform materials. I've read a bit about "sonorous tonewoods," and I'm curious. I note your following comment: "When the Sheesham board is allowed to resonate without dampening its natural-sounding sonic characteristics, it helps present assertive dynamics and a full-bodied tonality without stepping on more subtle listening cues."

BTW, a two-piece audio component can benefit from different vibration control footers and platform approaches under each piece for fine tuning that's considered better optimized to one's ear.

I think that this is an excellent observation -- and goes to an issue that's been on my mind as I consider how to deal with my phono pre-amp separates. While both the power supply and main amplification units are entirely tube-based, it strikes me that they may benefit from much different vibration-control approaches. It sounds like you may be in a similar boat with your pre-amp.

So the particular board is for placement under the preamplifier unit.

As opposed to the power supply ... because?

Notice the rubber gripper pads at each corner on the bottom of the board.

They look like a disaster from a vibration-control standpoint! Does that mean I'm finally starting to catch on? ;)
