Only Joseph, and perhaps Victor, knows what the new cap in the 2.1 is. He is keeping it proprietary. The copper foil around the new cap is not there to hide anything about the cap. It is there as a shield to block out EMI/RFI. I doubt if the cap is from Claritycap, especially the APW, as it is an inexpensive cap and Victor once mentioned that their new caps in the TP 2.1 cost them around $80.00. The Hovland is a musical cap, but it does have its limitations, hence, Joseph's change to the new cap in the 2.1. Joseph will be soon evaluating the new Claritycap MR series and I'm looking forward to his impressions.
