I doubt you will find anyone who has heard both those rare CDPs. I'd put my money on the Consonance, being it is a non-oversampler.
Consonance A120 v. Unison Unico
Has anyone had the opportunity to compare these models? I owned a Unico and a Unico P at one time and was quite happy with both. There are 2 A120's for sale on Audiogon right now in the $600 range that I might be interested in. I have a pair of Triangle Heliade speakers. Thanks.
