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 grounds...it seems like quite a bit already
Thanks

In parallel with in any amp section. The amps will not be plugged directly into the Z center. The amps go directly to the wall FIM outlet
In series with the digital side using the isolation outlets on the MIT Z center. thanks
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...

That's my "dirty dozen" -- sorry if I may have missed some other really good ones. These should answer most of your questions. Note -- the first thread referenced 74 other posts of interest (I did not check these out, but Bob Bundus is one of the "guru's" in this area). Hope that helps. I don't have anything to add above what is in those posts.
Remember ... Think with your ears!
I once had seperate ground rods driven with no hum problems. THen two different guys on audio asylum showed how my seperate ground could be used as a direct path through my system by a lightning strike (i live in one the plains states where thunderstorms can be big entertainment). needless to say i disconnected the ground rod and stayed with the common house sustem ground (which is the only code compliant way to do it anyway). a few months later a near lightening strike did claim a couple of tubes and some fuses in my amps, which were not protected by a conditioner/surge protector.
