Hi y'all-- I'm finishing putting together a new HD2 Accel system w/ the following: Pendulum Quartet BM6A monitors 90% of my analog recording consists of running a bass and guitar(s) direct into a pre (with the guitars then going into Amp Farm or other modeler), and live vocals. I don't record live drums or mic'd amped guitars. Occasionally, I'll record an acoustic guitar or sax. So taking all that into consideration, are the Digi converters enough, or will an outside converter make a visibly noticeable difference? Thanks again!
