VAC Signature Mk IIa SE vs Pass Labs XP-32


I am considering both of these Pre-Amps and was looking for anyone that has heard both or has a strong opinion one way or another.  Rest of System Includes:

Chord Dave
Chord M-Scaler
PS Audio BHK Pre (Looking to move this to the family room system and upgrade for my main system)
Antipodes CX + EX
Pass Labs XA-60.8 Monoblocks
Harbeth Super HL5+

My understanding of both is that they are highly resolving, superb sound-stage and both add a sense of warmth.  Based on the specs both should work without issues.

I ended up with the XP-32 and have not looked back.  Demoed it against the VAC and no comparison on which sounded better to my ears.
