Thanks everyone! I think I’ll start off by bi-amping. I like knotscott’s idea of adding a solid state integrated amp for the woofers to match volume levels unless I can find some solid state monos with the same gain as my ARC 160M’s (gain of 25.5 dB into 8 ohms).
ghdprentice, I’d like to use all ARC amps but I’ve read that I really should use solid state amps for the woofers and ARC only makes tube amps. Hopefully I can find a dealer to let me demo both a second pair of ARC M160s and solid state amps for the woofers but the system is at my home in Lafayette LA and there are no nearby dealers. Or maybe the ARC Ref 320s for the woofers, but their website said they were supposed to be released in 2022 so I’m wondering when they will be released with their recent financial trouble. I’ll try to post photos of my system.
Once I can afford it I’ll try tri-amping, probably with appropriate hi-pass filters for the mids and treble. Or maybe I’ll be satisfied with bi-amping.
FYI there’s a good YouTube video by PS audio which concludes replacing good internal passive crossovers (which the Aidas have) with active external crossovers is not worth the trouble.
