Dear Gary: Your analog set-up ( Helius&AN tonearms ) can handle almost every cartridge.
I like the Ruby2 and I like it with Classical and Jazz music but with your electronics the Ruby3 will be a little better.
Now, I insist in that the Genesis168 is a very good alternative. Btw, I know very well your AN speakers ( I asume you already up-graded. ), when somebody look at them it can't imagine that something so simple at the " look " can give so great quality sound reproduction, congratulations!!!
About the tonearm, the AN ones are very good, I never had the opportunity to mount one of them in my audio system but I heard it on other system and I like the design and build quality. If you can go for it.
Regards and enjoy the music.
Raul.
