Well, interesting experiment tonight. I went direct to the VAC Phi 110/
110 with the APL Denon 3910 and tried Zero Negative Feedback on the
VAC. Eureka! No distortion. Even though I had tried going direct to the
VAC with the APL, I hadn't tried it with Negative Feedback switched off.
I'm bittersweet though, because it tells me there is a mis match between
my First Sound Presence Deluxe II and the VAC, although the system
sounds terrific with the First Sound in the chain and with the VAC's
Negative Feedback enabled. Now, I need to devote some listening to
both variations to decide which is better.
