I don't know much about the Rendu other than what I read just now after doing a google search, but my first thought was why fix something that isn't broken.
I like all the parts I can still work on to make it sound better, when I first got the touch I thought it was just OK and then Wayne hooked me up with a nice linear power supply...night and day difference. I can still swap out a dac whenever I want to try a different sound or just roll tubes in my current TADAC.....options, options, I dig options but like I said I do not know much about the whole setup.
I'll follow this to learn from you guys.....
