Jan, excellent clear instructions that you put together in the thread you link.
Have you tried other gauges of magnet wire? Any reason why not? It occurs to me that the little bit thicker versions would have the same expected benefits of 30 AWG but would be a tad bit more sturdy.
Your enthusiasm is making me want to try the magnet wire version with solderless RCA's. Maybe they would be better sounding than the 100% silver thin wire interconnects I made. Only about $10.00 to try.
(Don't tell DUP that adding water to gasoline in an internal combustion engine to decrease compression detonation (that is, increasing the effective octane) actually works very well; high output supercharged engines produce even more power when they also incorporate water injection.)
