As always, less noise equals more signal. Be it UHF noise from WiFi or Eithernet infiltrating our components, switching noise on the AC, humming transformers, noisy transports, hissing power supplies, tube rush or ground loops, the mantra of high fidelity playback is always less noise for lower distortion and higher resolution. In those terms the heavy-duty Base Diamond is a resolution enhancer. "Only the newer Evo model with the stainless steel top can be upgraded to Diamond, not the original model with the felt top. I will send you four complete new footers. What do you think if I send them with the softest green 'super light' ViscoRings installed to first try under a component? DAC or preamp/integrated on either system might be a good choice. I'll also send four of the same blue 'medium' ViscoRings currently in your footers which you can then switch to for use under Martin's sub. The process to switch the ViscoRings is the same as before. I agree with your original assessment that footers typically make little difference under equipment sitting on good racks such as your Artesanía and Hifistay. However there is still a lot going on between ~10-50Hz where the footer will isolate better. Worst case, the difference will be indistinguishable. But there's still a chance for a surprise." No try no buy. I was perfectly happy to try and already had a useful scenario in mind. "Let's."

Are you still hazy on swapping out squishy parts? It's down to viscoelastics working like springs. To operate as intended, their compliance or spring rate must match the load's mass. An obvious example of a gross mismatch is a car with shot shocks. Hitting a shallow road bump bottoms out. Jeff's viscoelastic sleeves come in 5 weight ratings to cover up to 800lb as a quad. Determine your component's weight, look up the matching color in Jeff's chart and he's yer rich uncle from America. Being able to float extreme loads makes his footers ideal to go under entire equipment racks to isolate them from floorborne resonances. Given BigMac size, that's even a fine cosmetic match. The same can't really be said for your average DAC/preamp. Below those these industrial Texan beefcakes look a bit grotesque. Beneath most speakers and subs meanwhile, they look just fine. They work regardless and size is simply predicated upon what Jeffrey determined was the ideal geometry for his viscoelastic sleeve doing the vertical anti-jackhammer isolation job.

Enter euros. Exotic materials x precision machining = inevitable costs. At €599/ea. a set of four Diamond Bases sets us back €2'400 minus a cup of coffee. There'll be joy wherever just three can do the job. To mental calculus, €1'800 worth of structural isolation feels nuts under a €2K component no matter how effective. That balance changes with a €20K turntable or still costlier pair of speakers. Once we trade continents and look farther north to Ansuz, footer fantods can really fly off the handle at maximally €3'500 each for the below.
