Interesting product range that seems to be rationally priced, including some nice looking audio racks.
Note they offer IsoAcoustics as an option for their audio racks.
I use IsoPucks between my Harbeth 40.3's and the Ton Trager stands. How much difference they really make I cannot tell - I moved houses, installed them immediately, then treated the new room a bit and it seems like to much work to a/b test them - surely they can't hurt.
