Ozzy,
To add to what Bob says, I have the equivalent of the weakest SCTH filter (mine are Aether Audio Black Box versions) on my treble boxes and I have Spectron Musician III Mark 2 monoblocks (and currently eval'ing the Sanders Sound Magtech amps..both very high power amps). The filter level is perfect; I would assume your SS level is too much for such a resolving and high power amp as the Pass's. Drop down a level or two and you'll be amazed! Amazed I say. :)
