Sheesh. You
completely forgot to test how difficult it is to turn the knobs. Come on, man!!!
No, serioisly, very nice work. If there's a better A/B comparison between these two systems, I'd like to see it. Can't think of anything, really, that you overlooked. Still really enjoy my SA220 --
which fits just fine, thank you, on the floor right behind the front seats of my little Toyota! -- but there's no doubt that these are both pretty amazing systems, IMO, in what they do, what they cost and how little space they take up. And fortunately, there are some significant differences that will matter to different people to help them decide. Anyway you did a great public service here, sir; thanks!
