whoa that seemed a little hostile. not sure if it was directed at me or the company, but I guess I should clarify a few things. The website actually list it as gold platted silver soldering I assumed it was the signal path. My post was a guess as to why they need gold plating on silver soldering, and I am not an electrical engineer or someone that has built any kind of amp. My guess was based on my limited knowledge of circuits and batteries for my physic, chem, and biochem classes. If I presented myself as someone that has knowledge of either the companies reasoning or any background in amp making I apologies. that being said if you could enlighten me as to there design choices it would be much appreciated.
