I just spend a coupla grand on the best studio monitors, signal processors and monster cables. I just finished connecting everything and, yay! I just met the studiofile's worst enemy. You spend the extra money getting the best cables and monitors only to have to deal with ground loop.

I isolated the problem to my dbx 266xl compressor.

It seems that there are two solutions:
This: http://www.sweetwater.com/store/detail/CleanBoxII/ for $35.
What this does is break the ground in the audio cables.

And this: http://www.sweetwater.com/store/detail/HumX/ for $70.
What this does is safely remove the ground from the electric signal.

Does anyone have experience? Is there any other solutions?

It would also work - and be much cheaper - to use a 3 - 2 prong electric adapter - http://www.adorama.com/ZZAC32.html for $1.50, but all the article's I read on ground loop say this is dangerous and can cause electrocution. Is this really the case? I've never heard of someone being electrocuted because of one of those... and we're only talking about a signal compressor - not a refrigerator. (As you can tell I'm trying to get out of spending another $35 - 70 -- but not if its trully dangerous.)

Thanks in advance,
Chony
