@mattmiller Stanton 881s MKII was a choice of Doug Sax (RIP) if you know who it is and if you don’t know look at Sheffield Lab studio gear. This is his master disc monitoring cartridge for years. Doug Sax did the greatest Direct Cut recordings of all time. This cartridge cost under $250 today (used) or even cheaper if you’re lucky to find one in the USA. I’m not gonna say it’s the best MM cartridge, because there are better Stanton cartridges out there like the signature SC-100 WOS or 981 series, but the Stanton is clearly better than 2M Red and the price for that Stanton is pretty low.
Here is the article about 3 top carts used by the greatest mastering engineers from the golden age of vinyl, those carts are Technics 100c MK4, Audio-Technica AT-ML170 and Stanton 881s MKII.
I hope you’re not trying to say that modern Ortofon MM cartridges are better?
Unfortunately Ortofon M20FL SUPER is no longer available - that was a good one with Fine Line stylus.
Not sure how many cartridge have you tried, but i have tried many of them and still trying/looking for something that can surpass the vintage MM, but i can not find anything that comes even close to some of my favorite MM carts, they are all from the 80s, but i was born in the 70s and i have not tried those carts until now.
In my system i use at the moment: AT-ML180 OCC, Grace F-14 LC-OFC, Grace LEVEL II MR/MR and Stanton CS-100 WOS ... and many others... they are all superior to the 881 MKII for sure, but the price for those carts are 3-5 times as much and they are easily competes (on the right tonearms) with 3-4k MC cartridges.
BTW I owned Dynaudio Contour 1.1 (bookshelf) with powerfull Dynaudio SUB-300. Dynaudio is definitely not my type of sound! Sold them long time ago.
I find my nirvana with super high efficient (101db)
Zu Audio Druid MKV full range speakers instead (no crossover). It’s completely different sound and that’s why the source (aka cartridge) is important for me. I also drive them with new tube amp, so i’m not the one who stick to the old gear, except for the cartridges and turntables.
