No, ground is ground. It is either grounded or it is not. The extra ground wire or terminal is doing the same thing, grounding. The only detriment to not grounding is hum or buzz....if it is not doing that, then you are properly grounded. Ground does not carry a signal.
Does Having the Turntable Grounded Through the Right RCA Effect Sound Quality?
I have a Thorens TD-160MKII (that I've posted about before). Does the way Thorens (and some other makers) ground through the right channel have a negative effect on sound quality? What's the advantage/disadvantage? And why do most makers seem to do it the other way with the connection going to a separate terminal on the preamp?
Thanks.
