Turntable isolation platform Recommendations?

@Mijostyn- yeah, there’s something on the bottom, but I also was concerned that the metal top of the Minus K would have a sound and liked what the HRS brought to the package, having used it for some years before getting the Minus K. The one downside is that the HRS winds up distributing the weight across its surface, to its contact pads compared to the naked parts of the TT being in direct contact, with their mass less "distributed" (ala the HRS platform). I think that made it harder in some ways to balance with the two arms. I’m not sure what other Minus K owners are doing, but most don’t have the XL so it’s hard to compare notes.
I will say that anybody contemplating a table like this better have a good set up plan in place-- when I had the Kuzma Reference it was set and forget- the internal suspension was quite effective and no need to go to extraordinary lengths. With the XL you have a lot of weight/mass and must isolate it effectively. Maybe less of a problem for folks on a concrete slab, but for situations like mine-- you can’t easily hang it from a wall (I had a structural engineer look at it when he was here for other work) and any placement on a springy floor is going to be "exciting"-- especially with that air bearing arm, which is in some ways less tolerant of things like edge warps (or footfalls). FWIW, Franc Kuzma is one of the best people I've dealt with- responsive, fast turn around, and he likes dealing with customers. I will visit him next time I'm in Slovenia!
I’m not really contemplating a different table, but we will see. Focus next is on speakers, but that’s not going to happen overnight. I need to do some traveling and listening.

I think the Townshend Pods are great bang for the buck and I use them myself.  But I don't pretend for a minute that they perform at the level of SRA platforms....it's not even close but my wallet is happier for the choice I made....it's all about priorities of where we put our money in audio.

The preferred method for isolating a turntable is a quality wall shelf that will stop the vibration and bounce from having the table on a suspended wood floor.

@speakermaster- normally, I would agree that a wall shelf is usually a good alternative and cost effective. I'm dealing with a turntable that is about 170 lbs with one arm, add another 30 lbs for 2nd arm pod (not in use right now) and the HRS plinth adds around 50 lbs, I think.
I had a structural engineer here (I thought I mentioned that in this thread, maybe not), but I had the idea that they could mount a steel ledge from the wall in combination with the brick fireplace flue (unused as a fireplace). The house, which is an 1880's Victorian, was completely restored, from foundation to roof, but the engineer said the walls would move in conjunction with the floor and nixed the idea that a wall shelf would work for my heavy table. Not all turntables are this massive, though and the wall shelf approach should be explored as a first option, at least if the problem is potentially footfalls. When I had a brownstone in Brooklyn Heights, using a much lighter table, the wall shelf worked extremely well. 

That kind of mass on a wall shelf can be bad news. Walls flex also actually, worse than floors because they are much thinner. Hang that kind of mass on a lever arm and you get a very springy affair. 
As whart implies, mass is not isolation when it comes to low frequencies.
It is a shame to have to put that beautiful table on an ugly MinusK platform. I would sink the MinusK into a cabinet so only the upper surface was visible. Anyway, this is life with turntables.
@whart , Look at the Schroder LT tonearm. Just a thought if you wanted to get rid of the compressor. If you are ever up in New England I'd be happy to demonstrate Sound Labs for you. But, judging from your room and taste in gear I'm not sure they are the speaker for you.
