Thanks, JohnK, for saying what I wanted to say! When I skimmed the Burson site, I thought to myself, ah, more smoke and mirrors. (The tweak market will love this stuff.) I did recall the output/input impedance "ten times" rule and 50,000 ohms input impedance for the receiving device was still lodged in my brain from bench testing years ago.

Thanks for confirming that with the 47 kOhm figure.

Regards,

Alan
