pass labs x250 talon khoruses and bat vk-40

thanks for that quick response,
do you know any about that pin allocation issue on xlr interconnect,
a fellow that i've purchased a cable from said that BAT and Pass run two different configuration of balanced connectivity. (weird stuff IMHO)
the BAT VK-40 pin configuration is:
pin 1 : common (shield)
pin 2 : positive
pin 3 : negative
can that b truth that the pass product would be
pin 1 : common
pin 2 : negative
pin 3 : positivity
should i attempt to invert the polarity of that cable.
is there even a need ?
my ears probably wouldn't b able to tell the difference,
if there was one.
all opinions are welcome.
tnx
David

If the BAT is really brand spankin' new out of a sealed box then you really need to break them in.

A few more questions what brand of cables are you using? and what power cord or power conditioners?

Are you still using the Rega for source?

Pass is pin 2 positive. BAT is pin 2 positive also but has measured pin 3 positive. Contact your dealer or get an electronics friend with a MM or DMM to measure.

i'm still using the rega planet 2000 as a source,
my cables r inexpensive mid-fi ones (thinking about replacing to homegrown audio cables silver lace xlr and rca

will a standard xlr cable do the job here or the polarity needs to b inverted? (the above issue again, im all confused now) (pass pin 3 positive while bat pin 2 is positive)
thanks
David

Pass as follows
Pin 1 ground
Pin 2 Normal input or positive input
Pin 3 Inverted input or negative input
