quartz as shelving

Onhwy61 is in fact speculating. Unity Audio speakers like my Green Mountain speakers use a synthetic marble to eliminate cabinet resonance. This has nothing to do with placing your equipment on a rock hard surface that will make your system sound bright and glaring.

Uru975, Notice the photos of Onhwy61's systems. His equipment is on wood. There is a good reason for that. Stereo equipment on wood is known to give the best sound.

marble, granite, glass and your quartz countertop are kryptonite to your stereo equipment

Yet you have speakers made from synthetic marble! What am I not getting?

Stereo equipment on wood is known to give the best sound.

If this is such a well known "fact", then how come HRS, Sistrum, Arcici and Gran Prix (4 very well regarded stand manufacturers) don't use wood platforms?

Rather than talk in absolutes and make hyperbolic statements all I'm suggesting is give the quartz material a try and let us know how it works. I freely admit, again, that I'm speculating that it might work well.

(As a personal note, I do use maple boards under some of my equipment. I also use carbon fiber, MDF and acrylic. At one point I used 1" thick glass which when combined with rubber/cork mats worked well. I then switched to a Mapleshade wood/metal stand which was a definite improvement. I'm now seriously considering taking out all the maple boards and switching entirely to acrylic, except for the one carbon fiber piece.)

What you are not getting is, I don't use my speakers as a shelf to set my equipment on and speaker designers use this material for speaker cabinets for reducing cabinet resonances.

I think you should take out the maple and replace it with quartz. Then you can tell us how bad it sounds.

Now do you get it?

So reducing resonate behavior in speaker cabinets is somehow different than reducing resonances in equipment shelves and different materials should be used?
