My Kuzma rig is up and running and I am pleased to say it has exceeded my expectations. I picked this thing up in hopes of having a decent sounding turntable on hand for when the mood arose, but had no realistic expectation of matching the quality of my Well Tempered Reference... I having spent a couple days with this (not even optimally setup, mind you) I can say without reservation that I prefer the Kuzma.
Unfortunately, I wasn't able to get it going with my Denon 103-D. Upon mounting it, its age could be heard, so its going to be headed into soundsmith for a TOTL re-tipping, which I understand to be a huge upgrade to the already tonally great cartridge. Right now its making great music with a Dynavector 20xH which has many, many hours on it as well.
I don't know why this thing flies under the radar. It really is fantastic.
