oofer, here's a tip... I see on your Inmate Systems page that you don't use a power line conditioner but, if you do aquire one someday, your DH Labs power cord is excellent for connecting a power line conditioner to an AC wall outlet, IMHO. It's not as great when used on other gear (again, IMHO) so, I think you will like the Flavor 4 upgrade for your preamp. Cheers

Duster,
I think you are correct. When I got the first Flavor 4 from Chris, I replaced the DH Labs cord with it at my amp. Very large difference. I mean REALLY large difference. It is okay at the preamp, but I have a few more pulsar sets to get and then the pre gets a boost.I have tried several power line conditioners including Ron Wellbourne's latest, but they seem to have a negative effect on dynamics. Anyway, my power is pretty clean up here in rural, coastal Oregon. I do have some issues I am working on, however.
I have a satellite TV receiver from DishTV hooked into the system which puts out a DC charge to power the LNB's. I have recently isolated and damped it down pretty good by changing from balanced to single ended connections between my pre and amp. Then I used the ground lift on the amp. For some reason, this did the trick. I may star ground the equipment soon, too.
My speakers are really efficient so every damn stray bit of electrical muck pops out. Right now I am 98% of he way to dead quiet. All in all I would prefer to use balanced connections. The specs I have seen on my equipment show a flatter, wider response curve with the balanced. But the RCA connections' 6 db drop in efficiency has really helped quiet the whole system.
I also had a problem with hum, so I had my CATV guy install this in the main CATV coaxial input feed to the CATV juction box and it keeps DC out of my whole-house in-wall CATV coaxial cables. It's is an excellent product, without degradation, and very inexpensive...Cable Isolator w/ Spike Protection (CISP) $11.58 + free shipping

BTW, what type of AC outlet arraignment to you use for your system? Are all of your components plugged directly into a wall outlet or do you use a multi-outlet power strip?
Well, Hi Duster! Thanks for the suggestions and help.I have heard that cable isolators don't work on Satellite TV set ups. I suppose for the price I could try it. I just didn't because of what I have heard from others. The 75 ohm coax comes directly from the antenna to the decoder from whence it receives its DC.
My AC comprises two #10 romex, dedicated circuits. One for Analog equipment, one for digital. They use the same leg at the panel. Plugs are high quality with copper/brass grounding legs and very tight interior connections.
I have tried hooking up a separate #10 wire from chassis to chassis between the amp and the sat box. There is a slight improvement, but I fear either an outside static charge or lightning grounding itself to the amp with its ground lifted might do real harm for slight improvement.
Frankly I have been thinking of pulling the TV system away from the the two channel system entirely. I really like the hookup for movies and the Sirius music channels, though. Compromise, I hate it.
The cable isolator would be useless then (oh, well).Have you seen these? (see link below):
Perhaps you could try the Auricap Tweak on your AC outlets. It has no compression of dynamics that I can detect.
RF is everywhere...
