The knobs are a no brainer. Those $450 jobbies will do, unless there are better ones. Anyone have the link to the audiophile power cables?
The rules should be something like no gratuitous spending on diamond knob pointers or solid gold bus wire, unless it's pseudo-scientifically proven to make the sound better. Can we spend a million bucks on a head and cabinet?
I found speaker cable for $7k/m
I found a luxurious fabric for the grille that is $4k/yd
Maybe one of the rules might be a fake budget to by an historical piece of hardware to use as a donor? What is a space shuttle made of? Would it sound better made out of space cycled aluminum?
How simple a circuit can we get to over a million bucks?
