What can I say? I am a physician. I don't need to peddle anything. I am sharing BY FAR the best tweak in my 45 years as an audiophile. I have ten 640X AC filters, power distributor , 2 sets of the newer speaker 640X, a Black Body 10X power base, 3 of the Stellar AC cables-forgive me if I got some nomenclature wrong, I'm not into that so much. System: Project CD transport, LTA power supply, Audio Mirror T5 DAC, Goldmund 590 int amp, Adam Audio speakers, various Stillpoints and Carbide Base Footers, Neo Dio, Ground boxes from Scotland (forget the name), Puron plug ins and Audio Magic ground device, 2 Tombo ground purifiers, various acoustic devices. Yup I'm a fraud. BTW I'm a psychiatrist , just saying.
