Capri and Concerto internals are extremely different--Capri being a brand new design based on TI Burr Brown OPA1632. However, not having had the opportunity of a direct a/b audition, I am not in a position of offering my own comparative findings. Rather, I have contrasted the Capri with the ARC Ref 3 for about 3 months and currently prefer Capri on most all audible parameters, in particular for extension, bass control, overall linearity, low level detail, harmonic development. Macro dynamics is comparable. Slightly more romantic and slightly darker the Ref 3 than Capri. Overall two great pres for slightly different musical tastes. I have posted some more detailed findings in other related threads on Audiogon.
