Without taking this thread OT, I would like to briefly interject that I recently purchased from Peter at Symposium Acoustics a custom "Svelte Shelf" for an atypical use-case, whereby, I needed a custom Svelte Shelf with only a 11mm height, rather than the usual 5/8" height (~16mm). As background, I explained to him my height constraint in-between the skeleton shelves of my Finite Elemente Spider rack, and he proposed a solution - an ~11mm version to solve my dilemma. Upon receiving my custom Svelte Shelf this week, I inserted it underneath my Innous Zenith Mk 3 + Innous Phoenix combo, which (unfortunately) sits atop my Equitech 1.5Q balanced power isolator/regenerator. With the sensitive Innous clocking equip (server/streamer/re-clocker) placed on top of a huge toroidal transformer inside the Equitech, I knew I needed some help. With the custom Svelte Shelf now in place, the sound reveals a huge uplift via noise floor reduction. I was hopeful it would help, but I am thrilled with the exceptional SQ uplift. The low bass in my sub is much clearer, the mids are deeper, more textured and cleaner, and the highs now have a clarity and a real solidness in imaging. The whole sound-scape is improved. And as a result, listening fatigue is also reduced. Even my wife hears the ease and newfound clarity. In my use-case, I believe the Svelte Shelf helps my system with:
1.
Mu mitigation - reducing the electromagnetic influence produced from the Equitech's large electronic flux onto the adjacent Innous combo (that resides on top). In the attached photo, you can see the front edge of the Svelte Shelf just on top of the bottom black component. Peter said the Mu protection would be significant with the two layers of stainless steel, and the inner cavity that the insulation in the middle provides. He has measured the dB's of the Mu attenuation of his shelves previously, and his Svelte Shelve has certainly demonstrated its effectiveness to me.
2.
Vibration dissipation - the core anti-vibration technology in-between the 2 stainless steel outer layers enable vibrations to dissipate into heat, and as a by-product, drain vibrations away from the sensitive electronics.
Last but not least, the Svelte was produced in very substantial gauge stainless-steel, and cut and polished to a very high standard. The darn thing is (unexpectedly) heavy. Moreover, the packaging it came in provided excellent protection during shipping, and the box and stuffing are certainly re-usable. No short-cuts were taken here. Exceptional quality of the product and scope of delivery.
Hope this feedback helps others as they review their challenges, and consider potential solutions.
