Firochromis, don't rule out the Manley's. I have them and love them. I haven't heard the Frank's, though. It would be nice to hear from someone with experience from both amps in the same system. My Manley's are partnered with a Manley Steelhead pre and the combo is pretty stunning. I'm sure there is better out there-- but I am not interested in changing. Coincident gear may be the better value after the Manley price increases.
