differences can be shown somewhat with measurements

if I wanted to go thru the trouble I could demonstrate lowered clock noise/jitter on the scope, it is there trust me, anyone who does SDI mods and deals with the main 27mhz clock knows that the stock Oppo units are a mess when it comes to the clock, horrible jitter

I also had a professional customer in the past send me some before and after noise floor measurements with some modified pieces I did for them

stuff like this

Roger, I will be addressing the balanced power issue soon, thanks
