Great to hear you are in Godzone! My kids are 50% Kiwi ... and I run a Perreaux amp. As your past Prime Minister said when flying into Sydney and told that New Zealanders had the highest crime rate of any ethnic group in Bondi "I don’t know about that, but my statisticians tell me there is a net outflow from New Zealand to Australia and it has the effect of raising the intelligence levels on both sides of the Tasman"
When you say
What I do know about digital is that it dumps a lot of noise into the earth as well
can you clarify whether you mean the earth wire in the power cord, or the planet at large? In remote areas, Australia also delivers power by SWER (Single Wire Earth Return) which means that only one wire is run to a property, usually on poles, and the circuit is completed via the ground (the planet), When training to fly gliders, SWERs were counted as a real hazard during remote landings - the poles are way apart, and the wire is virtually invisible but deadly.
In my opinion, audiophiles should concentrate on the electronic noise coming from their own equipment, not noise supplied by the power company. What do you think?
