Analog Upgrade itch

Hello ! I would like to upgrade my turntable / tonearm / phono preamp 

currently I am using Kuzma Stabi S / Stabi S VTA 12” tonearm / Gold Note PH10 phono amp. 
Gryphon Antelion EVO + Pandora pre , Magico A5 speaker. 

My music preference : 50% classical / 30% pop / 20% modern Jazz 

I like my current cartridge: Etsuro Urushi Cobalt so I am going to keep it. I would like to upgrade my Turntable (possible Linn LP12 or Kuzma Ref2 or any suggestions ) with Kuzma 4 point tonearm (or recommendation in the $ range?). My biggest uncertain is phono amp : I’d like to have warmer sound (tube preferred ) with ideally 2 inputs (Manley Steelhead or EMT126 are recommended by my local dealer but not sure if they are worth the money ) .  I know matching (cartridge / arm / phono stage) is more important in analog system so I’d like everyone’s comments / experience that matches my system. Musicality / warmth is what I’m after rather than microscopic details. Thanks in advance
