Which Mono block amps for ML Summit Speakers?

Well, I would definitely recommend tubes. Audio Research because of their output transformers which have taps down to 2 ohms; but there may be other makes of tube monoblocks which have that same capability. You'll have to check the ML website for power requirements, but I'll bet they'd do nicely with 150W per side, since the bass is self powered.

Go balanced interconnects if your preamp has balanced main outs. If you do select tube amps, then I'd also recommend a SS preamp, or a tube preamp if you decide to go with SS monblocks. If you do go with SS amps, consider some of the older Levinsons like the 23.5 or 27.5, which are well within your price (used) and they are amongst the most musical of all SS amps ever made; as opposed to Krell, Rowland, Bryston, etc. which I feel are a bit bright/edgy for this application.

I just checked the ML Summit specs. The built-in woofer amp is 200W. Recommended external amp (for the panel only remember!) is 100-300W. None of the prior ML speakers had on-board amps, and thus would have employed a completely different electronic interface between the power amp and crossover -- so I feel that amp/speaker experiences w/ previous ML models must be considered anecdotal when speculating what would work best with the Summit, which is decidedly not an evolution of their previous hybrid models.
