Most satisfying system change in 2017?

Three positive changes:

1. Clear Day Audio Double Shotgun speaker cables (2 pair)

2. Replacing PS Audio PPP with a P5.  An enormous improvement.

3. Replacing 24 year old Aragon 47k phono stage with Sutherland KC Vibe.

@stereo5   That accounts for the abrupt jump in McIntosh stock!😉
