pre for Pass xa60.5

Hi all

just got my Pass xa60.5 and i'm looking for a pre upgrade. Currently I drive them with Lector zoe tube pre (which mates my Lector cdp-7). I usually lean towards tube preamps although I'm not fixed on tube.Budget is around $2500 for a preowned unit.

mu current short list is:

First sound presence
Aesthetix calypso
joule electra la-150
or maybe older Pass models on SS.

I have very limited audition options and i usually buy based on reviews and Agon members' opinions - so every opinion counts.

Thanks in advance for each replier.
