Stillpoints Ultra SS vs spikes on concrete

I have two listening rooms, one on the second floor and one on the foundation. In both the StillPoints Ultra SSs were by far the best isolation I ever heard. In part they isolate both ways from the floor upward and from the component downward, but they convert the motion to heat.

I think the Syn. Res. MIGs and big MIGs are a distant second best and far cheaper.

I have probably twenty isolation devices still in my possession but have tried many, many others.

Glad they worked out for you; I'll be curious if your observations change over the course of a week or two (not to play devil's advocate or anything ;-)).

I would bet that the Ultras would beat the Herbies but they were too rich for me at the moment as we have 2 kids in college, planning a wedding, and just dumped 5K into repairing cars. For me this experiment was to see whether devices proclaiming to turn vibrations into heat versus spiking would make an audible difference. Now that I have established that I can hear this difference, I'll be looking to compare to the Ultras when I get some scratch.

As i said my opinion only. I put in some of Herbies/Gliders under a pair Merlin TSMXe speakers, on Osiris speakers stands. I let them settle for 5 days before listining. Bottom line i did not like them, too thin sounding, something just did not sound right. Called Bobby at Merlin, said DO NOT UNCOUPLE speakers from spikes. He said for his speakers they must be coupled to floor thru the spikes. Kept the Coplers, using under some BDR Racing cones on different equipment. Like thet say YMMV.

Ryriken. Might be that your speakers are designed to use the floor to add weight to the bass? Are you on wood or concrete? I am also now letting them settle in and will have opportunity with wife away this weekend to do some more evaluation. Then I will take them out and see if I am missing anything.
