Act- the arm itself is phenomenal and is really little trouble, once it is properly set up. It is well machined, well designed and pretty trouble free to operate. It needs to be absolutely level, and I occasionally clean the tube that the bearing travels on, so it doesn't get 'stuck' due to 'dust.' The pump is a whole other matter. In talking with SIL in the States, they think the pump is too small for the application, and that its behavior is due in part to having to run too many duty cycles. The Kuzma US distributor does offer a bigger SIL pump, with a larger compressor and surge tank, and i might try that once I relocate.
The Kuzma 4 point arm is supposed to be fabulous, and I might install a second arm at some point- easy enough to do- just buy an additional arm 'tower' and line it up properly next to the TT. The TT itself is a beast, and the biggest issue is setting it up for isolation. It is very heavy, and adding the weight of an HRS isolation platform beneath it makes it heavier still. The room is at the top of the house, with wooden floors, so you can imagine the challenge. I tried the big Finite Elemente floor stand that was made for the Kuzma XL and it just didn't work- the floor was too much of a challenge. Right now, the turntable sits on the HRS platform which, it turn, is mounted on top of a very heavy old Asian prayer table that is about 10 feet long and has to weigh several hundred pounds. My dealer helped- adding huge chunks of sorthbothane under the table and it works well.
Definitive Audio (if I remember the name right, the people in the UK that build those Living Voice speakers) have their Kuzma mounted to a wall, but the space is an old factory with much stronger walls than sheetrock.
I'm looking forward to Austin- and am planning to do a dedicated room there, with some basic acoustic design, balanced power and the rest. I think the system will sound better in a bigger, better designed room than I have now.
Always try to visit Symbolic Motors when I'm in San Diego, but it's been a few years. Here's my email if you want to stay in touch: bill@flyingreptilemediagroup.com
