Affirmative on that last sentence. Beneath the IQ speakers Greg's Vibron L was as effective as my residents. As such the swap didn't shift my carefully curated balance one bit. Only my bank balance would by quite a few bob were we playing finder's keepers. While I confirmed the bigger delta of the XL under the sub, I also sat atop it to push the load limit but couldn't generate any give. The XL's weight rating seems generous. The geometric concept and its practical behaviour are one clever bit of guerilla engineering by 3D printer and a smart progammer's chops. What's more, with its non-greedy pricing new brand Virtual Hifi is a friend of the common wo/man. Padre Grzegorz of Poznan for sainthood? Hey, there've been Polish popes already.

Whatever your views, making effective vibration attenuation this friendly opens doors to people who appreciate its theory and anecdotal evidence but whose pockets and life commitments must fry bigger fish. That strikes me as today's shiniest accomplishment: working out an effective isolator geometry, building it cheaply then selling it with a tight margin to spread out the joy across a broader base. In big-box retail it's often called a loss leader. It gets people into a shop whose staff is under strict instructions to either upsell them or bundle something with real profits like extended warranties. Not here. It's a web shop. No pushy salesmen. No pressure. Sell yourself. Or not. If you paid attention, you already know how Greg's Qualio IQ Ultra bundles IsoAcoustic's Gaia 2 footers. For those Amazon just then wanted £600/8. His own Vibron L above and below gets 1/3rd. 'nuff said. If not saint, perhaps we should paint Greg a kind of hoody Robin rascal who steals critical auditions from costlier competition then brings similar results to those starving for better sound for a lot less? Still too pretentious? Over and out then before the sheriff of Shannon puts me on a 'wanted' poster.

Let's finish with a proper Polish joke. A Polak sees a priest walk down the street. Noticing his collar he stops him and says, "excuse me but why are you wearing your shirt backwards?"
The priest laughs, "because, my son, I am a Father!"
The Polak scratches his head. "But I am a father too and I don't wear my shirt backwards!"
Again the priest laughs. "But I am a Father of thousands!"
To which the Polak replies, "well, then you should wear your shorts backwards!"

Postscript: In the same saintly vein there might be this? And whilst we're still on same veins, hours after publication I learnt that Artesanía of Spain, the company of my double-wide rack in the above system, will have their racks in 17 (!) exhibits at this year's Munich show aside from their own room. The company they'll keep will include APL, Audionostrum, CH Precision, Constellation, Danish Audio Excellence, DIVA, Engström, Gershman, Innuos, Kroma, Magico, Mårten, Matter, Métronome, Orpheus Lab, TechDAS, TrueLife, VAC, Von Schweikert, Wadax, WestminsterLab, Ypsilon and Zellaton. At our industry's biggest international show where brands struggle to make stand-out sound which attendees will recall after it's all over, resonance control is a subject taken serious indeed. With today's Vibron, you can already get in on the serious act without acting all serious.

Virtual Hifi responds: Thank you for the great review. Indeed the Vibron are priced Robin Hood style. Since there is no heavy-metal machining involved, manufacturing costs are very reasonable so amazing value. Also, I'm not really a fan of everything in the audiophile world costing tens of thousands of dollars so it's my small contribution to restoring sanity in our niche. – Grzegorz
