@syntax -thanks, noted. I remember the Kuzma Reference- had one, very easy to set up, sounded good, had a Triplanar on it at the time.
@mijostyn- I had the HRS in NY and was able to isolate the high mass table through a combination of mass loading and judicious placement of other equipment. There were some old photos of the system there I could dig out that show the table placed on a huge old Asian prayer table- we added huge chunks of sorbothane to the prayer table legs, but it was a kludge work around at best. In my NY set up, the HRS alone could not isolate footfalls and in fact, I think that some of these isolation platforms do not do that very effectively. The Minus K does.
The MinusK was purchased when I moved- to a restored Victorian house in Austin with springy wooden floors. As to adding the HRS, I didn’t like the idea of the metal turntable coupled to a metal top on the MinusK. I did speak to the owner of HRS and as I recall, he didn’t indicate any issue when I discussed using the HRS with the Minus - he did suggest I send the HRS back for a newer footer, but I didn’t bother.
You are welcome to visit if you come to Austin.
PS: on the spec of the Minus K, it takes the HRS into account and also provides me with just enough load capability to add a second arm pod (at 30 lbs). I had never ending problems trying to balance the Minus K with both arms, though. See
here. Have no present plans to add the air bearing platter to the XL, but thinking about some different horns. That’s a whole other discussion!
