Jneutron, let's get a few things in order. I want to thank you for the 45 degree theta Jc model, but it is next to useless for most engineering. Of course, if you are looking at an UNKNOWN thermal resistance of an arbitrary shape, then it becomes useful. However, most engineers, like me, just find out what the thermal resistance of a transistor spacer is from the factory specs. It saves time.
As far as low level distortion is concerned: I don't like nickel much, myself, and I'm sure that it adds to non-linear distortion in many instances. Personally, I don't care whether the distortion is generated by Peltier effects, cross-lattice distortion, impurities, or whatever. I just measure significant distortion in some wires, and almost no distortion in others. That pretty much excludes my internal wiring, connectors, and the resistors, etc, that connect to the RCA jacks on the cables. I have found that I must regularly clean my connectors with quality isopropyl alcohol, and sometimes, even stronger cleaners, to keep my reference wires reading low. Does this say anything to anyone out there that you should clean your contacts once in a while? I would hope so.
All in all, I have no reason either to include or exclude your Peltier 'distortion' mechanism. You have not shown by measurement or formula that it is all there is, or that it is important enough to include, with my test set-up. This is why I tend to ignore internal argument, and just let you go on and on. No hard feelings I hope.
