Hi Bob,
It`s hard to know if it would be better than your SET amp or just different. I agree with you the only way to positively know is to get it in your system.
I`m curious to hear it and compare to my Coincident Frankenstein 300b SET. So far it is the best I`ve heard(for my priorities and taste) especially with the marvelous Takasuki 300b tubes in place.No amplifier is without some flaw or degree of compromise in some aspect of performance.It really boils down to what particular characteristics matter most to a listener.
Best of luck and sucess to you.
Charles,
