I experimented with two separate runs from the dual outputs of the various preamps. Despite preamp manufacturers saying this works, I found that, with 47 foot interconnect runs anyway, that it does something deleterious to the sound. I know it's only supposed to be about capacitance and treble roll-off, but I felt like there was something else going on.With your linestage in a different room, how do you run cable and at what lengths to the two amplifiers?
So I have one run of interconnects connected to the Gryphon woofer towers which (even when the towers are off) has an unadulterated through-put out.
