Mike,
Yes, but only the iso blocks, triplepoints, surefeet, threaded footers, and the smallest 2 shelf rack, and they have all done great things for the components I used them with.
My Signature 70s are sitting on three SureFeet (2 in the front corners under the batteries and one in the center rear under the circuit board) which in turn are sitting on a pair of 12" x 15" x 2 timbernation Tiger Maple board that are resting on isoblocks on my bamboo floor, and it really made a significant improvement to the amps -- smoother, warmer and better tonal balance.
I also had my Omega Revolutions on triplepoints on a 4" timbernation block with 4 heavy carpet piercing heavyfeet sitting on my carpeted concrete basement floor and that alone was like getting a brand new pair of speakers.
I will be getting a 3 shelf V.3 rack like you mentioned for my new setup because I know they are solid and sonically very beneficial -- from my experiences so far. This little 24" high 2 shelf V.1 rack could easily work as a jackstand for the rear axle of a cement truck -- ok, maybe slightly exaggerated, but once setup and tightened, this thing just doesn't budge or rattle even the slightest bit.
I ended up selling the 4" blocks and heavyfeet to ZLS for his new Omega hemp bipole XRSs and he said they made a substantial improvement (using myrtlewood blocks to support the speakers.)
I've never tried the ICs, SCs, or power cords and outlet strips, and most likely won't -- mostly because I'm happy with the choices I have and their physical construction seems just a bit too flimsy and awkward to work with.
HTH,
Jim
