    Hi, Guy...

    The washers are fine, but that is not your biggest source of the GL. You will need to unplug everything and work backward from the amps (upstream) toward your sources, plugging one source's signal in at a time, until you find the culprit. That signal will need to be isolated from the system using some isolation transformers. There is a thread here somewhere that discusses this. Radio Shack has a cheap and very effective cable for this - works great.

    have not read the complete thread in detail, but feel I have been there with the x-over hiss.
    There is a forum that covers the Behringer and describes a passive output stage, the mod is easy and makes a huge difference to the hiss. It will also drop the output by about 15dB.
    I also found unless you are driving the x-over properly it will sound real compressed at low volumes, the only way out of this is to have a 6 channel attenuator after the x-over, the same forum covers this. In the ned I gave up and went back to my L96 3 ways and added a sub.
    Best of luck.

    I switched out my MiniDSP balanced crossovers with a Xilica XP4080, and the hiss is gone.

    One of the reason I like my BGW 620B's so much...Alps attenuators.

    Nice. How do you like the Xilica overall? Nice interface etc....?

    Thanks,

    I've got an xilica crossover that I'm very happy with. I do the programming via the USB on the front and the program is easy to use.

    I like it very much. It has a little learning curve, but not much. Once you learn it it is very easy to use. I prefer doing most of my adjustments with the web interface which is very nice IMO.

    I had the balanced 2x4 in a box version (not the kit). I originally had the unbalanced and loved it, but when I went to the balanced version I had a hiss problem. I am not sure if most people would hear it, but in my setup it was hearable from over 12' away. With less efficient speakers it might be fine.
