I would be surprised if anyone here will know the answer to your question. Personally I think that details such as this will not make a very audible difference in guitar amps, if any at all. I advise you to not get trapped by vendors of snake oil and waste your money on details like this. You might end up becoming a hifi guy, spending a fortune on gold plated power inlet cords. At the end of the day more than 70% of your tone is in your fingers. I bet Jimi Hendrix would still sound waaaay better on a digital Roland amp than any of us on the most desirable vintage amp. Just saying
