Audio Racks, Just How beneficial? looking for guidance in upgrading


Greetings all. Looking for guidance and your experience in racks & shelves for the ’sweet spot’ and upgrading. Do you find that applying a percentage of your total system’s value of perhaps 5% or even 10% is a good metric? Do you folks find that some of the leading Audio Rack companies, like HRS, CMS for ex., which seem great but is it beneficial to warrant spending well over $15k , $10k + or $5K on vibration isolation for a mid level system. Racks are really hard to demo; I’m reaching out to Audiogon community.

I’m trying to get my arms around some of the price points and the cost/benefits.
Anyone find wood is sonically better?
Doesn’t seem to be that much between A/V furniture manufactures and the better companies. Prefer a Modular approach like Bassoconuinuo- (anyone have it? I haven’t priced it yet.) or adjustable shelves. (not that keen on Solid Steel).
I need 6 shelves including top for turntable.
Currently have a BDI with glass shelves; using still points, or BDR cones, maple butcher blocks. Yes, I know the glass shelves...have to go.
Thanks!

@tomic601 - On my gear, the SMc Gravity Base is simply a (nicely cut and powder-coated) slab of brass, attached to the bottom.   I believe one of the attributes apparently contributing to the improvement in performance is that the Gravity Base is not simply attached to the bottom of the equipment chassis but is also directly attached to key internal components such as transformers, etc.

SMc does make a Panzerholz Isolation Base (and pt. 2) and they will also build their VRE-1C Preamplifier out of Panzerholz.

Here are some off-hand observations: the market developed for racks which provide isolation and those can get pricey. Not dissing them, it is one choice. 

The alternative is to use basic, substantial racks of some sort and do the isolation part with commercial or DIY products.

I've owned a lot of stuff over the years: Finite Elements, Adona, Billy Bags, Grand Prix Monaco (which requires you to replace the sorbothane pucks periodically) and others.  I've owned the Grand Prix stuff since the aughts, a rack for gear, with carbon fibre shelves and apex footers (also on my speakers), as well as a home made rack for the digital side (constrained layer damping) and a rack for the turntable made for Minus K, which is welded steel with a phenolic top. 

If I were starting from scratch, and on a budget, I would look for substantial racks that allow you to mass load them. And deal with isolation by experimenting. I use Stillpoints for some stuff and other stuff dependent on the Grand Prix stands/racks.
