Welcome to the club, i like Grace cartridges, F-9F (Shibata) was my favorite before i tried Level II BR/MR, F-12 and F-14 LC-OFC models.
Unfortunately the Ruby F-9 is elliptical, so it make sence to upgrade with SoundSmith’s Line Contact in the future when you need re-tip. The most advanced and affordable Grace is LEVEL II (Boron cantilever / Micro Ridge stylus tip) and it is wonderful cartridge, the F-12 is impossible to find and very expensive, the F-14 LC-OFC is amazing, but also very expensive.
