I have tried bi-amping through the AK5 network of my Klipschorns with two 300B SET amplifiers. I first tried using the vertical method and then horizontal. I prefer the horizontal bi-amping method, but did notice that one speaker was omitting a loud hum when both amps were running. The hum went away if either amp was switched off, so I imagine this may be an earth related issue within my pre-amp (Supratek DCT Cortese).
