NORDOST SORT FUT VS. ISOACOUSTICS GAIA

Critical Mass 1 1/2 2M better than both of these by a wide margin.

“Nordost product worth it”
 

NO, Gaia I’s were lot more effective underneath my B&W 800D2 than Sort Fut.

Just read Critical mass's product description and wow what a marketing statement.

"The LS series of Center Stage² products reduce stored loudspeaker cabinet resonances and entropy to a vanishing level resulting in enhanced clarity and musicality across the audible spectrum."

How do feet reduce cabinet resonance? they reduce cabinet movement (maybe that's what they mean), isolate from the floor etc. 

they use a lot of fancy technical words and it boiled down to a load of marketing hoopla IMO, 17 years developing feet, must be some of the slowest engineers around. 

I've been in the submarine technical industry for decades and we do a lot with noise reduction, vibration analysis. noise isolation, etc and this marketing hoppla sound like bull @$#^ to my ears.
