Dear @dgarretson : Nice to " see " you again, in many threads we need you.
" livelier ", well that's exactly what SAEC owners including me think about those double knife tonearm designs.
As a fact I owned 3 SAEC's and I bougth due to the comments of Japanese audiophiles opinions I found out elsewhere including the advertasing through the USA distributor Japanese Stereo in CA ( seveal years ago ) and those opinions came in comparison between the SAEC 506/8000 vs the Micro Seiki MAX 237/282 that I owned too and those audiophiles said exactly the same as you for the 3012R and the Kuzma where for the Japanese the Kuzma was the MAX 237/282.
That's why I bougth the SAEC's when I already owned the Micro Seiki's and yes the SAEC was " livelier " and the MAX tonearms just as your opinion of the Kuzma till I learned first from where came that " livelier " and second why the MAX was really a superior tonearms.
The livelier came from the knife bearing with its tiny " rattle " and in the other side that the SAEC's are not a well damped design: more or less like the 3012R.
When I learned and even that the SAEC's looks just great and were build with a very high quality levels I prefers the MAX all the way down and till today. The MAX is perhaps one of the best tonearem designs and along the Lustre GT-801 the only dynamic baknce design that just does not ring like a bell with its VTF set up mechanism..
Even that great MAX/Lustre dynamic balance characteristics I ended using both through gravity forces that's the natural way for VTF.
Dgarretson, as I said before each one of us like what we like, it's our privilege.
Welcomed,
R.
