Which Mono Cartridge at around $1,300.00?


I'm in the process of upgrading my well cared for Thorens TD145. I started by soldering in WireWorld phono cable along with getting a basic tune up. I want to replace my Grado ME+ mono cartridge with a substantially better mono cartridge. Currently, the tone arm is stock. My records are classical (orchestral, chamber, vocal, etc...) dating from the 1940's and 1950's so I've been cogitating on the Ortofon SPU Mono GM MKII or a low output Grado (i.e. the sonata reference 1). My phono stage is the ASR Mini Basis Exclusive. All or any suggestions would be greatly appreciated.
Thanks!

I don't understand the need for a mono pickup. I play mono records with my LPS and am very pleased....many times it sounds better than their stereo versions...
I found a price for the AT33 at $445.00. I'll admit that at this price it certainly is tempting.
I agree some of my mono albums sound better than their stereo counterparts even when playing both with a stereo cartridge. That outcome surprised me. Reason alone to pick up some mono vinyl even one doesn't have a mono cartridge (eg my mono version of Ben Webster soulville kills the stereo version).

Robin Wyatt can be reached at 1 (855)-robayatt and the website that shows product he carries is robattauido.com. He has a step up transformer specially built for the Miyajima that's awesome and less expensive than cinemag 1131. I needed the ground lift feature of the cinemag or would have been just fine with robin's SUT. U can always run the Miyajima straight into phono preamp without an SUT just like any cartridge. I find the SUT brings more dramatic impact out of the mono vinyl. A fun reason to have 2 cartridges.
Pryso, thank you for the clarification!

BTW, I see nothing problematic with Goofyfoot's interest in an Ortofon SPU Mono (first post).

kind regards, jonathan
