Not at all Scott. The 'rejected' IC had a similar price to the one I selected. It was YOUR AD797, that sounded OK, BUT was extra expensive. And why is it that expensive, looks like price gouging to me! That is why I resisted putting it my design, even though my design was originally made with it in mind. In future, IF I am forced to, I will revert to the AD797 in this phono stage, and pay the extra price, but if I don't have to, why bother?

For everyone else: This just came out today by an esteemed audio competitor who has similar decisions to make.

There's this device, very comparable to a dowsing rod:
fake bomb detector - Google Search
From Wikipedia:
The ADE 651 is a fake bomb detector produced by the British company Advanced Tactical Security & Communications Ltd. ATSC claimed that the device could, from long range, effectively and accurately detect various types of explosives, drugs, ivory, and other substances.
I have several pianos, and one has real ivory keys (original for this nice 1964 piano, perfectly legal, well before the 1973 ban), I wonder if a blindfolded (because you can guess by the brand name...) person could reliably tell which piano has the ivory.

I don't stay away from the absurd - if it's important and/or I have some time and/or it seems like an interesting problem, I investigate it. There's often some mistake or something I overlooked where what seemed absurd was actually me misunderstanding what's happening.
 
Hi John,

... And just how much does Scott have to do with the pricing of an IC he designed? I have a suspicion that the higher price might be due to the amount of silicon needed to make the die. That would be my first guess.

Dousing doesn't strike me as so far-fetched. The ability to find water by reading subtle clues from terrain, plants, who knows what-all, would have been a valuable trait in our East African ancestors. That, and Wayne's uncle's insight, could be survival critical, so selected for.

Anyway, seems in a different category than Second Law denial, magic goop, etc. Just my opinion, natch.

All good fortune,
Chris
