Right!, so the crossover then goes to some home-brew amps if so what are
they and are they bal or unbal inputs?..

Balanced. Using THAT1240 ICs. The whole idea being to avoid ground loop
problems...

They have some serious CMRR.

I doubt the X/O has anything like that?

I didn't recognise the number on the balance ICs in the X/O.

I have loads of SSM 2143 I could try, though, on the amp. But I've not had
problems with either before.


Wouldn't surprised if they were pin compatible!..

Because the cable run is so short, I've just used the most basic circuit
for the THAT1240.

But

It really shouldn't matter those sorts of chip can take balanced lines
up to miles long if need be!..


I've got/getting rather then theres something odd with the power supply
for these somewhere?..

Can you describe it in more detail?..
