[Clamping Method vs SMD AD-1 Amp Dyno vs. SMD AMM-1 Audio Multimeter]

And for the record, I'm one if those people who doesn't personally own the proper meters. I'd love to own an amm1. Makes things very idiot proof, much like the other smd products

But if I owned 1000+ in meters that could get damn close, I'd keep my $400. Haha. But I'm no pro

Pain in the ass but it you have the proper tools to clamp, I'd rather have the pain in the ass than buy another tool that does the same thing as the 2 meters I already have. But for people that don't own the proper meters, the amm1 is a good option.
