I had Druids with their mini-method sub in my setup for a few years. Very clear and dynamic, no doubt due to the minimal crossover components. I ran them with both 500wpc Class D and Atmosphere M30s, and they definitely had more magic with the tubes, but that was only a loaner amp at the time.
Now running vastly different speakers, 1985 vintage Infinity RS2b, totally gutted and rebuilt. The ribbon mids and tweeters do something for vocals and minimal music that the Druids just couldn't, but the Druids rocked out better...they can take massive power without missing a beat.
BTW, my 200wpc SET project is progressing (about half done). Still waiting on the custom OPTs from Belgium. When completed I'll host a rave in celebration.
