GrooveGrinder,
(must be an LP fan!)
I use my G*S*G to drive these speakers all the time. The combination sounds exceptionally good.
There are several pictures posted at the link address as well as pictures of quite a few of the amps and other speakers I've built. They are Zaph Audio BAMTM's, which stands for Bargain Aluminum MTM's. Lots of bass as well as high end extension. Fairly inexpensive and easy to build. Web site is here:

Good luck with whatever approach you decide upon.
