RKny and Pinkus, I will leave the PC1 on the Capri at least until the end of next week. Then I will take it out and will repeat listening of some key tracks. For the time being my observations are still tentative and, and need to be validated with more rigor, because they also involved an amp change, and the tracks I played were not the same.
On configuration A, consisting of X-01 Limited, Rowland 312, Mahler v1.5 I listened for a fiew hours ARC Ref 3 and pure Capri. Capri appeared to yield a somewhat more defined harmonic content, extension and overall authority than Ref 3, at the cost of perhaps an almost umperceptible excess of energy in the mid lower bass (plucked double bass).
On configuration B, consisting of X-01 Limited, Nuforce Ref 9 V2, Mahler v1.5, I used a CD of Monteverdi madrigals with 2 female mezzo sopranos, countertenor and positif organ to listen to Ref 3 and Capri+PC1. Findings are similar to configuration A, except that I would replace the term 'somewhat' with 'unmistakable'.
Or in other words, I perceived a greater delta in favor of Capri when PC1 was included.
Please note that my observation are purely relative at this point, I am not at all implying that I preferred the sound of configuration B over configuration A; only that -- according to my initial very unscientific observations -- Capri+PC1 may be affecting my own system positively to a greater extent than Capri by itself.
