Anyone tried active biamping with Martin Logans?

"Successfully driven". That means you could hear the music play. Not much more.

I've heard a pair of Soundlab A2 being driven by the McIntosh MC1201 monoblocks. These are rated at 1200 Watts at 8 ohms. Even with that power, the Soundlabs could not produce a volume level that I wanted without setting off the protection circuits in the amps. Sure, they successfully drove the speaker, and the Soundlabs sound great, however not for me.

Having been a ML owner, I would look for solid state with high current, doubling down.

Best,

What is your budget? I have owned four different pairs of ML's....... From SL-3's to Prodigy's, and many different amps (tube and SS). I always preferred tubes. I had good success with ARC VT100 II (Used $2000) and Sonic Frontiers Power 2 (both 100 wpc). I also used a BAT VK75 SE, and Nagra VPA's (50 wpc). Either the ARC or SF amp should work very well in a moderately sized room. You might also look into a pair of the Rouge 150's, or VTL 150 for a little less money. All of these amps deliver a lot of current (as opposed to the voltage of the SS amps).

Well, I paid $1,350 total for the Aeriuses, two Adcom GFA-5200s, and an Adcom GFP-555. Next thing to get upgraded is probably my Harman/Kardon CD changer - I'm thinking a used Rega Planet might be a good, affordable move. Possibly Straightwire - braided (low impedance) for the woofers and coaxial (low inductance & capacitance) for the panels if I go the active biamp route.

Still, I'm interested in learning about tube amps in case more change turns up in my sofa cushions.

"All of these amps deliver a lot of current (as opposed to the voltage of the SS amps)."

I thought SS amps generally could deliver more current into low impedances than tubes (e.g. 50W @ 8 Ohms -> 80W @ 4 Ohms). No? The Adcoms are reportedly good at this.
