For our electrical engineer members: Does using a "Y" splitter on an interconnect cable to direct a pre-amp output signal to two different amplifiers for bi-amping cause any impedance problem?
Does having the dual amplifier loads derived from the same interconnect alter the source/load impedance seen by the input of each amplifier?

It may or may not be a problem, but the impedance definitely changes. For example, I have a solid-state amplifier I use to drive my sub. It has an impedance of around 10K ohms. I also have a tube amplifier I use to drive my Quads in my system. It has an impedance of approximately 100K ohms. The 100K load is an easy load to drive but when I add the 10K load of the solid-state amp, the load is more difficult to drive. As a consequence, the pre-amp I use should have a low output impedance. If I only drive the tube amplifier, I don’t need the pre-amp to necessarily have a low output impedance. Hope this helps.
