Thanks for sharing your knowledge about these wonderful cartridges. You didn't mention but obviously know about their wonderful sound, and I assume also value the light tracking, this AT150e body/ATN160ml beryllium/microline stylus combo happily tracks at only 1.25g.
I joined the forum, got a lot of help here, and began changing things just before Covid in late 2019, ended up completely revising 3 systems: Main (back to tubes); Office; Garage/Shop. Then, after creating my 3 arm TT, and finding a great Sony SACD Player xa-5400ES recommended here, I restored 2 pairs of AR-2ax speakers. Had 2,500 then Inherited over 4,000 lps, mostly Jazz played once or twice, much great Mono content prior to Stereo LP's in 1958. Gave away/sold over 2,000 LPs, more need to go.
Lately I have been assembling a small collection of alternate cartridges.
My 'long in memory' reference favorite is the Shure V15Vxmr, MicroRidge on Beryllium Cantilever that tracked at only 1.0g. I used it (until I broke the beryllium cantilever) in my SME 3009 II Arm (which I renewed with help from SME) on my Thorens TD124 TT (which I renewed with help from Thorens).
All correspondence by mail in those days. I'll never forget the reply letter from SME: expecting a price quote, SME simply trusted me to pay, and shipped me the parts with an invoice here to the USA. Made me feel like a trusted gentleman.
