Dear Lleall: There are a lot of land to make improvements in your audio system that can fulfil in a better way your music/sound priorities and you said that the kind of music you like to enjoy is rock/pop that in many ways has high demands from an audio system.
You can change your cartridge for a better one and then you could have a better quality sound but the cartridge signal will be reproduced as good as how that cartridge signal was/is surrounded. IMHO for you really can appreciate in full what any cartridge has to shows you need first rate audio links over your audio system. So, I don't recomend to go to a cartridge change but before improve some links in your audio chanin.
You like rock and even that your speakers are really good are limited on its frequency range and you mated it with tube electronic amplifier that IMHO is not the best way to go. No, I don't want that you change your amp but something that could help a lot to those very good speakers and to your amp too.
If I was you my first move will be to add in full stereo fashion a pair of active subwoofers crossed to 80hz to liberate the speakers/amp from 80hz and down. This sole move will improve the main speakers/amp quality performance level in many ways ( you will be surprised on the kind of improvement. ) and in the other side now you will have a full range audio system with the best bass management you can get and IMHO is in the bass management where reside the foundation on any home audio system. As better that system bass management as better the whole audio system quality performance level.
Here you can read something about:
