A lot of people like tubes with ML speakers. I use Odyssey stratos Extreme monos which are a solid improvement over the Stratos mono. I do not think that B&K or the PS Audio work well with the larger MLs. However, with the woofer pulling the bottom end I think almost anything will work.
I also heard the EVo amp sound spectacular with the SL3.
