Do equipment stands have an impact on electronics?

It was back in Nov 1995 in Stereophile magazine that Shannon Dickson published "Bad Vibes" - the landmark article on vibration isolation and also the Vibraplane iso stand that had recently come out. IIRC there were then only two isolation stands in high end audio - Vibraplane and Sesimic Sink from Townshend in UK. I debuted my six degree of freedom Nimbus Sub Hertz platform with Mapleshade at CES Jan 1997. A feature of Nimbus was actually provided by Shannon Dickson. Even back then the Nimbus featured a single air spring of correct geometry, the world’s best air spring, an axillary air canister, and cryogenically treated steel rods that supported steel ballast below decks. I later introduced Promethean Base, a steel spring based ISO stand at CES 2000 and 2001 followed by much smaller cryo’d high carbon steel springs, Cryo Baby Prometheans. Now I have small cryo’d springs for every load from 1 lb to 300 lb. My Super Stiff Spings are for really heavy loads like large turntables and amps and subwoofers. Since cost is NOT an issue for my springs, we’re practically GIVING them away, ALL COMPONENTS in the system can be isolated at LOW COST - and since the springs are very low profile (about an inch high compressed) they have outstanding lateral support. THUS in most cases they can be placed DIRECTLY under components. I recently introduced the Bio Mikro G "Woody the Woodpecker" isolation stand that is not a spring-based ISO stand. I have constructed a dual layer ISO stand, a trick I learned from LIGO. Dual mass-spring layer devices are very tricky and not for the timid or young.

Ironically my small springs yield the same resonant frequency as the Vibraplane, about 3 Hz.

is this thread now about turntables?

no

No Randy, but turntables are arguably more than any other component affected by the stand they are sitting on, as well as from all other sources of vibration. The physical dimensions of the LP groove walls that the cartridge is "measuring" are on the order of microns, often smaller than the amount of physical displacement in the legs and/or shelves of the stand the turntable is on.
