Bought it from forum member
conquerator2 but I have documents and purchase date is 05-12-2013 and according to Philips webpage it`s
manufactured in 2012
(it actually says presented in 2012).
I took out X1 box again and measured stock cable again:
ground to terminal 1 through left driver - 35.1
ground to terminal 2 through right driver - 35.8
ground to ground = 2.4
terminal 1 to terminal 1 (right channel) = 2.4
terminal 2 to terminal 2 (left channel) = 2.5
I changed it to self-made Van Damme Pro Grade Classic XKE Pro-Patch cable (smaller OD), terminated with Neutrik Rean gold 3.5mm and Neutrik 6.35mm jacks.
ground to terminal 1 through left driver - 31.9
ground to terminal 2 through right driver - 32.5
ground to ground = 0.8
terminal 1 to terminal 1 (right channel) = 0.9
terminal 2 to terminal 2 (left channel) = 1.0
Difference between cables:
ground to terminal 1 through left driver =
3.2
ground to terminal 2 through right driver =
3.3
ground to ground =
1.6
terminal 1 to terminal 1 (right channel) =
1.5
terminal 2 to terminal 2 (left channel) =
1.5
I`m trusting my ears
