Pre-amp recommendation

Hi
My 2 channel reference setup is almost complete.
I'm looking for a suitable pre-amp to complete the setup.
A few that I'm considering :
Cary SLP 05 (used)
Cary 98
Pass Labs X02 (used)
Budget is limited to $5K.
Any other brands are also acceptable

My setup
Source : Esoteric K01
Pre-am : Densen B200 (for now)
Amps : Threshold SA/1 mono blocks ( Mids & Highs)
Sub Amp : Gallo Ref SA
Speakers : Gallo 5LS

It's almost impossible for me to audition so any help will be highly appreciated.
Thanks
