Refinement through upgrades shifts into lots (and lots) of money, Scott, once you reach the kind of threshold that, on my view, the IDA-16 presents. The TDSS upgrade was worth it, but I had already sunk $$$ into resonance control (buying up Infinite Elemente after they went out of business along with older Stillpoints stuff, current Stillpoints are, no doubt, better but here we have the "lots and lots" of $$$$). If you haven't yet "done" systematic resonance control ("whole system" honestly makes a difference), it's worth it. But, then, yes, NuPrime has proven that it knows how to deliver what I take to be the best value available.
So, yes, I, like you, Scott, am very interested to see the approach NuPrime will take with the twice-as-expensive IDA-32. At my age I could be looking at my last integrated upgrade (he said....).
