Rrog: Leo is also saying that the Stage impedence will not be problem, which is what I also said. However, you said "while this may not be a problem for your monster tube amplifiers it can be a problem for other amps"
I do not think it will be a problem as any amp with 100 WPC or so will drive the Stage well.
