dedicated lines. what goes where?

Hi. I am finishing my installation of 4 dedicated lines. There are two dedicated grounds for these lines
My rig includes:
spectral monoblocks and preamp
theta transport and Dac
sigtech "equalizer"
MIT power conditioner
My plan is to put the monblocks and the preamp circuits to one ground and keep the digital stuff on their own grounds (all grounds are supplemental to the main box anyway)
Does this sound right? Or should I bit the bullet and drive a couple of more seems like quite a bit already

Dedicated (meaning separate?) grounds that run to different ground rods...sounds like the beginning of trouble (ground loops, hum...etc). The whole idea is to have a single, common ground in a system. If each is at a different, even slightly, potential (voltage) you will have current flow through the ground causing who-knows-what... When all of the grounds are common (as in most all electrical wiring and systems), by definition they are all at the same potential (voltage) and no current will flow.

If you read through some old posts, you will find those reporting improved performance after opening up the electrical panel and re-tigtening all the ground and common line connections. Many connections leads to contact resistance. The resistance causes voltage drops and that causes unwanted current flow.

All grounds should be common and this include cable TV connects if that's any where in your system. Multiple ground rods are good, just tie them together with 10 gauge solid wire and make sure all connections are tight...
