Need advice for upgrading my analog setup

Hello,

I got into records 2 years ago and have been using ProJect Carbon Debut Evo with a Sumiko Rainier cartridge. It has served me great as my first table and a way to see if I would enjoy playing records. Well I do enjoy records. And my dad gave me all of his records too (he's a CD guy but never abandoned his collection when vinyl fell out of vogue).

Anyway, I'm planning to upgrade my entire analog setup and I'm very much a buy once , cry once kind of person. I'm looking at a SOTA Sapphire, Origin Live Zephyr tonearm, and a Soundsmith Zephyr Mk.III cartridge. Is this a good combination? Are there any other combinations of gear in the $6k range I should consider? I try to buy American as much as I can. I've looked at VPI but I like the look of SOTA much more.

Oh and I'm using a Darlington Labs MP-7 phono preamp that I'm happy with and don't plan on replacing.

Thanks for reading and helping me out.
