Speakers for Jeff Rowland Model 10

Just bought one and plan to use with my Mini Utopias.

Any other users out there with suggestions of speakers, let's hear them!
Green Mountain Audio.......after all Jeff Rowland and Roy Johnson(green mountain) have worked together for years researching speaker/amp interactions. They have great respect for one another. Reach Roy at gma@pcisys.net
Dyna 25 Special for bookshelf
Dyna Confidence C2 for floor standing.

But perhaps need Model 12 to drive for C2
