Not as musical? Hmmm. It's difficult to see how filtering out audible frequencies can be considered more musical. Unless perhaps Robm321 is not employing decent or better line conditioners and/or perhaps has issues with ics and speaker cables.
Shortly after receiving my SCD-1 about 3 and 1/2 years ago, I experimented with the different settings. And perhaps once or twice since then.
In every case I've enjoyed the standard setting more than any of the cutoff filter settings.
-IMO
