The test set-up
Contents
We place the XP-22 where the XP-12 should be. Changing the guard is easy: change the cables and… done. The Pass Labs XP-22 now controls the Bryston 4B SST3 which controls another set of Focal Sopra No1.
As source we use our Metrum Acoustics Ambre and Pavane. The Ambre is connected to the Pavane via I2S. The Ethernet connection is galvanically disconnected via an optical converter. Cables come from Audioquest, Grimm and Kemp.
The energy for the Bryston passes through an Isotek Titan filter. The rest of the set is connected to a Kemp PowerStrip 8Plus.
