I have 3 dedicated lines with newly installed dedicated grounds. Since the dedicated grounds I now prefer my monoblock amps and preamp plugged directly into the wall, segregated from my digital setup which remains on the conditioner. Segregating the digital from the rest of the system was a major improvement as was the dedicated grounds.
Prior to the dedicated grounds I preferred everything on the conditioner. My take is that for dedicated lines to sound their best you must also segregate the grounds from the main house ground as feedback from rest of house contaminates through grounds. Dedicated grounds may be hazardous so proceed with caution. I still want to experiment with a dedicated condtioner for the amps and preamp.
