Hi John,
I don't mean to scare you. The RCA GC's to a DAC ground appear to affect the cable load and the clock looses sync and the bitstream quits. This to an external DAC with the RCA on that digital ground. Unplugging the RCA solves the problem in about 2 minutes and nothing further occurs. In my Sony SACD etc player, an external PCA onto the spdif with no external DAC connection also shut down the player. I had to turn it off to get the unit to reset. No further problems. So, the GC's don't hurt anything, they just make em mad.
As for the video application, I have been told that plugging an RCA into a video player is helpful. I don't know anything about these devices so I have no cautionary words. Blacker Black and more vivid colors were claimed in both conversations. I am a bit skeptical, but again, I have no experience here.
