Rum,
In the very near future I will be able to tell you precisely how the big Kuzma turntable with air bearing arm sounds. We will be comparing it to a Walker Proscenium with Walker air bearing arm.
The cartridge of choice for the test, a Koetsu Jade Platinum, will be moved from one arm to the other and carefully adjusted and set up by me.
The music I hear from Kuzma rigs at audio shows is great, but it's impossible for me to separate exactly what the arm is contributing. It would be difficult if I could luck into a demo with two competitive arms, identical turntables, matched cartridges, identical tonearm wire, proper loading values for the cartridge, exact gain matching during the audition and equal quality set up on both tables and arms :^).
All that being said, my instincts say the Kuzma is a world class rig. I have more confidence in it than the Continuum Audio Labs that's all the buzz.
Kha, the Graham had better bass than the Air Tangent in my system. The Air Tangent was mounted on a Basis Debut Gold MK IV. Later that same table was fitted with two Graham arms and had previously had other pivot arms (but not the ET on that table).
The Kuzma is likely equal to the Graham in bass, assuming it's anywhere near the Walker. The Walker arm has the best bass I have ever gotten but it's difficult to know how much is package integration, how much is TT design and how much is due to the arm :^).
When I hear the Kuzma I will absolutely know how it fares against the Walker and by deduction and previous experience might venture a "guesstimate" as to where it is against the other arms I mentioned.
