2 to 4 ok Copper boards with gold or Silver coatings . Are far more
accurate then point to point,much better conductors ,far less solder which is BTW only 4-5% silver ,the rest just tin, lead a Quality board it’s far more consistent ,no matter
what anyone said it is a fact, as long as the circuit boards are quality ,which a good company will use,now there are Ceramic boards with thick Copper traces ,that are what is by far the best ,and lowest in noise currently out there . With a Solid state amp
far too many parts ,time consuming ,and not as good ,point to point is mainly done in China ,No Thanks .
