i'm going down the rabbit hole fast. haven't been able to install my gaias yet but got in some of the iso-pucks today and put them under my dac, transport, and tube preamp.
bass is tighter with more impact. highs and midrange a lot clearer. sound is more analog sounding.
my problem is my mastersound compact 845 is 75 lbs so i could get 4 iso-pucks for $120 or 3 of the better orea pucks for $240.
i also have an ayre 100 lbs+ power amp that would take 6 iso-pucks at $180 or 4 of the oreas for $320
the iso-pucks come 2 ea. per box for $60, they hold 20 lbs ea. so you have to figure out if you are going to put 2 or 4 under your equipment.
if someone decides to try these and likes them and if you have an odd number left over i'll be glad to purchase them from you.
