I am really looking forward to the final set up. As I understand it Vinnie will pair the Isabellina DAC w/ the headphone module of the Amphora. However instead of using the stepped volume pot he will use the same pot used in the Isabella. The volume pot can be wired to control the headphone amp volume as well as variable output via the rca's to a separate amp. Also he may not use the V-Caps and will explore the possibility of using PIO (paper in oil) Caps. All of this for a price to be determined but around $2k to $2.5K.
Hope I have it right.
