Hi guys I've been on the forums for a while now but never have actually posted anything. I have a question about diamond buffer amps, I am building the RJM Sapphire headphone Amp for an electronics project (Amp found here: http://phonoclone.com/diy-sapp.html) What I want to know is what is a "Diamond Buffer" and how does it work. Any information would be helpful. Thanks In Advance Guys! Caleb.
