Need Recommendation: Phonostage

[Killergurt]

Hello all,

I am interested in upgrading my phonostage, taking my sound to the next level. As of now, it is weakest link in my setup and I could use some advice.

My current setup:
Preamp: C1100
Amps: MC601
Speakers: Focal Scala V2
Phonostage: JE Audio HP20
TT: Prime Scout
Cartridge: Cadenza Bronze
Cables: Cardas Cygnus

There are 4 phonostages that I am interested in and can afford, but won't be able to audition in my system prior to buying. I could really use help understanding the differences and/or issues and get a sense of what would be the best one to get for my system. They are a mix of SS and Tubes:

1. Zesto Andros Deluxe
2. Esoteric E-03
3. Pass Labs XP-17
4. Audio Research PH-9

Thank you for your help.
