Choice between Pass Labs & Constellation amp

Currently I want to change my 5 years old Electrocompaniet AW-180 mono block power-amp, my choice is between:

Pass Labs X-260.8 Mono-block
Pass Labs XA-60.8 Mono-block
Constellation Audio Stereo 1.0
Constellation Audio Mono 1.0

Unfortunately I have no chance to compare Pass Labs and Constellation amp side by side. And I never listen to ARC Ref 6/ 5 with new Pass Labs amp. Which amp you think is a better choice for me? In most of time, I only listen to modern Jazz music. And my listening area is small.

Constellation Mono 1.0 really out of my budget, but I want to know your comment how good if it work with my equipment. And these are the equipment I’m now:

Esoteric CD & SACD Player
Lumin S-1 Network music player
ARC Ref 6 per-amp
Electrocompaniet AW-180 mono block power-amp
Wilson Audio Sophia 3 speaker
Audience aR6-TSS Power Conditioner

THX!!
