Themarmar thank you for your response. I take it that you did not get to do a direct A-B comparison between your old CD306 and the new CD306 Ref? Also, I have a couple of other digital sources on the radar. I know that the old CD306 compares very favourably to the EMM Labs CDSA (if that PFO review is to be believed). I only wonder if the 306 Ref beats it.
I got to see one the other day. The thing sure is beautiful!
