(((Surprisingly, a Rogue Atlas Magnum II was not in the same ballpark)))
That's cause you would of had to open it up and install the output to the 4-ohm taps to get it close to working well.
I agree that Thiels are better off with Solid state electronic amps.
If you enjoy Phase and time, correct speakers, like Thiels you may also wish to include Vandersteen 2 and 3 series ,Treo's.and Quatros
to your list as these have a much easier impdence load on an amp and work great with Tube amps and solid state.
