Stax lambda NB - Left side seems weaker - Help

Thread Starter 

I've had my stax setup for a while, and I've always felt that the left side was slightly weaker.  I blamed it on my amp for the longest time, but It may not be the problem.  I would like to find the problem once and for all.  First, I would like to rule out or confirm that its the stax setup.

 

I am using an srd7sb energizer with my amp, and sr-lambda normal bias cans.

 

Is there a way to test both the energizer and the cans to see if the signal is balanced properly?  I have tested resistance on a pair of sr5nb before, so I assume that will be similar.  But what about the energizer?  I'd love to find out if its working as it should.

 

Here is the pinout diagram that I have, without the nb bias pin.

Thank you in advance.

Mods - I probably should have put this in the stax thread. If it can be moved, that would be wonderful.

WEll, the obvious is to borrow someone else's amp, cans or  energizer and see how the rest of your set-up works with it.

I would be totally down with that idea, if I knew anyone else in my area with normal bias stax.  I'm fairly confident that it is either the cans themselves, or the energizer, because I have tried a few different amps.  the effect is subtle, but noticeable.  I still have to test the resistance in the cable, but I'm pretty sure the cable is fine.  I dont notice any changes at all when the cable is flexed at various points.  I'm considering resoldering the connections in the cans.  If I cover up the diaphragm with foil or something, I shouldnt have to worry about solder or flux damage.  I'm going to try a few other things first though..
