The Parasound A23 / A21 amps have a couple interesting add-on features making biamp EASY.
First:
Each channel is single ended OR balanced in. That's not unusual
What IS unusual?
Each channel has a single ended OUTPUT, too
I take the single ended output from the input channel (left or right) and loop over to the OTHER input on the same amp.
NO Y-SPLITTER needed and input impedance is preserved.
Each channel ALSO has a level control, so if one driver is a little 'hot', you can tone it down a little.
At some point you may want to replace the OK potentiometer with a fixed resistor bridge OR maybe even a single-gang stepper of 1% or better film resistors.
Too much is never enough
