I’m contemplating using the 4 mono tube amps I have to bi-amp my speakers. They are different makes, how can I know if they are compatible for this. The equipment is:
2 McIntosh mc75 mono amps, vintage
2 Quicksilver silver 88 mono amps
1 PrimaLuna EVO 100 Tube Preamplifier.
Please give me as much information that can help me determine if it’s worth doing.
