Dear @artemus_5 : You already know that when we change the cartridge or the tonearm several " things " will be different, I can’t say better in your system because I never listened it and because I don’t know if the new tonearm just mates better to your ZYX and because I don’t know which are your MUSIC/sound priorities other that you like tubes.
When we buy a new audio item our expectations are high and I hope that after one or two months your room/system fulfill your today expectations .
Regards and enjoy the MUSIC NOT DISTORTIONS,
R.
