Analog Upgrade - Where to start?


I am looking to upgrade my LP playback system.  My current system is a mixed bag of new and old: SME 20/2 turntable (from about 2005), Kuzma 4 point nine Tonearm and the SME Series V Tonearm, Dynavector MC DRT XV-1s (retipped by Soundsmith), PS Audio Stellar phono pre.  I am looking to introduce more dynamic sound, detail (without edge) and musicality.  The rest of my system supports this end.  Any suggestions on where might be the best place to start the upgrade?

If you are considering an upgrade to the weakest link in your system, I would join the camp who are pointing at your phono cartridge. Actually, all your equipment is fine but a different cartridge can give you more of what you are seeking. There are many choices, (I don't make suggestion as it's your system and your choice) so do some research, talk to dealers, and do some listening. Good luck!
I guess Michael Fremer knows nothing about phono preamps since he speaks so highly of the stellar. Totally agree with rauliruegas.
@ OP,
I don't see your system listed so I have no clue what you got if any acoustic treatment at all. If you don't, that may be some of the best improvements on your system you can make.
On a more general note, anyone who discusses anything here and does not have their system posted makes it extremely difficult for me to take seriously. After all the system we each have is  truly what defines us as audiophiles. Just me.
