Emile, I do get they work in different ways. I'm curious as to the SQ differences that might result, and how this might free up Stacore duties for my cdp. I'll also try Daiza direct under cdp w transformer on Stacore as presently. I'm not too bothered by the physics, just the overall effect.It is an entirely different mode of action, therefor incomparable. I can see how you would be inclined to think "a platform is a platform", but it works the other way around.
