What Is The Darndest Thing That Made An Improvement Tweak Wise?

[Iving]

Darndest thing ... DIY aluminium-coated heavy duty record mailer stiffeners cut to shape and strategically located (trial-and-error) to shield sensitive digital circuits. Whereas RedNet D16 AES benefits most from proximate mains shunt(s), the DAC and etherREGEN benefit most from EMI/RF protection. SQ delta not trivial. tbh I have a lot of this stuff surreptitiously lining Hi-Fi furniture inc. transformer cabinet.
