UPgradeing dedicated line components


Six months ago I installed 3 dedicated lines for audio. One to amp, one to preamp, and one to digital. I used standard solid core 10ga romex for amp and 12 ga otherwise. I have a Square D box with distance to outlets not more than 20'. Used hospital grade outlets, however inexpensive ones.

I seek input on value of:
1) Upgrading the breakers in the square D box.
2) Replacing the romex for 10ga stranded cable for all lines.
3) Upgrading the outlets to PS audio or something of ~equal value.

Thanks in advance for any thoughts. Mike

Thanks Lacee, I did think about doing this myself. Makes sense to remove the outlets. Are the AC cables from the panel standard Romex?
I really wasn't expecting that much of an improvement when I replaced the entry level Cu IEC from Furutech with the Furutech FR 48 R.

Wow.
I was curious if I would notice much if any improvement,because the entry level IEC Furutechs were much better than the stock ones, how much better could it get?
I am glad my curiosity got the better of me.

A bit off topic,but I also did another upgrade to the RCA connectors on my 25 foot IC.
They had decent WBT type locking connectors.
I replaced those with Furutech CR 102 R.

Again I wasn't expecting a great difference,the IEC replacement was a gem, could I get lucky twice?

Yes.

The sound just tightened up even more, more reverb details and trails, and a smoother sound to massed violins.
I never heard Lambchop Mr M, Antony and the Johnsons strings sound as clean and full bodied as they do now, and I haven't even put more than 2 hours on these upgrades.
If more playing time brings further enhancements,this will have proven to be one of my better upgrades.

The lesson I have learned is that the connectors play a crucial role in shaping the sound.
Moved to a new home 3 weeks ago and have just installed an upgraded dedicated circuit. Main panel is Cutler-Hammer CH series with copper bus bar, subpanel is GE Master Load Center with copper bus-bar. The subpanel is tied to the main with massive 6/4 conduit and I'm using 10/2 Romex (for now,...other options too pricey at 16-25 dollars per foot, with 5 outlets I needed about 150 feet of cable) BUT I have installed an Environmental Potentials EP-2050 on the main house panel to protect everything and an EP-2750 Ground Filter on the dedicated circuit. I have heard nothing but good things about the EP units and that combined with the copper busbar panels should be a nice upgrade in the entire system's sound....very excited to hear the result once i finish unpacking!
