Tube-friendly speakers


I'm currently using a pair of Magnepan MMG's and a Hsu Sub along with my AES Six Pac amps. I'd like to move up to a larger set of Maggies, but it's been suggested that 60W of tube power would not be enough.

What are some speakers that would mate well with these amps? I do like the "planar sound". I'm most interested in something full-range, but could run a pair of monitors with my sub.

Tube friendly = high sensitivity + 8 ohm nominal impedance + flat impedance curve

The following brands are some that qualify:

Audiokinesis
Classic Audio Reproductions
Coincident
Devore
Klipsch
Living Voice
Merlin
Reference 3A
Some of the speakers in my list do not have 8 ohm nominal impedances (Merlin for example, which I believe is 6 ohm nominal), but they are still all tube friendly speakers.

Thought I'd cop to it before someone called my on it.
