I'm now breaking in the P and S polished receptacle and wanted to mention that its quite the performer. Sounds detailed and smooth as Paul says.
The Uber itself seems to be breaking in more as Im repeating some songs that appear to have more of a holographic quality which I quite enjoy. Will put some more time on the P and S polished and then move on to Furutech copper. Having quite the fun time  :thumb:

Thanks for keeping us all up to date, Nick.  It is asmazing just how much polishing adds, or more accurately takes away from the presentation.  Polishing the base metal helps to eliminate most of the micro arcing that will occur between connector surfaces.  Having highly polished blades is a very good adjunct to the polished contact fingers in the receptacles, too.  simply polishing the blades on a Wattgate standard connector and ing that with the polished P&S was my first foray into receptacle and plug modification and really opened my eyes (ears?) about surface finish being critical.I was going to polishe the FPX(Cu) too, but that is a pain in the butt to do.  Getting them apart is one thing, but reassembling them is quite another.  I can't swage the retainer ears.  I just haven't made the proper tool for that.  I have to silver solder them back together.  Once doe, that receptacle is very interesting.  I'll send you one you can just swap out with a FinalFilter already installed if you want.  Just let me know.

Thanks, much, Dave. I'll keep that in mind.

So, what is the latest scoop, Nick?  I'm very curious about your receptacle auditions.

Dave,
It's coming along well, but I've added too many variables. Gary has wanted me to add his power cord from Uber to the wall. So I finally did and it sounds good. He'll be at my house this Wednesday, so I'll be leaving it in for now. Break in for all receptacles is done, but I would now like to go back and disconnect my dac and finalize my decision re which is best for the amp. Then I'll repeat the process with the dac. I like the P & S polished, great sound and bang for buck.
Any of these changes result in a different sound. I need to analyze the change and see if it contributes to my goal of tonality and harmonics (this was Charles description in a recent post).
Interesting that bending Gary's cord resulted in a sound change. He uses solid 8 gauge copper. I had read about that phenomenon and it's the first time I've really experienced it due to the increased resolution that I have. 
I'll be getting the Nola's soon, so that'll be another change. But it's all a fun process  :thumb:

  The Uber takes 300 to 400 hours IMO to stop changing. Then ?? Bliss baby. Outlets two to three weeks [ 500] hours. Yes Sir bend a cord it has to settle in again.
Just went through another break-in of our new elec. panel and dedicated lines. 21 days to be exact. ENJOY!!!!

My father, Bud, my mentor and best friend ever (after I became a father and finally grokked the Old Man) would look at all of this and throw the bullshit flag.  He was an electrician for 50 years and believed in using the best components from a rational POV.

 I learned a lot from my Dad.

 Buy the best tools and save up for them if necessary. 
Tighten it, wait 5 minutes and tighten it again.  He taught me about cold flow.

NEVER do anything stupid with 250..  You "might" get away on 120, but don't press your luck.

With 220-250, put your left hand in your pocket or an insulated glove.  The left arm is right next to the heart's natural pacemaker.

Make sure every connecting surface is as clean as you can get it.  Clean it, wash it, clean it again.

Be particularly careful with DC, especially when a battery is involved.  He almost lost his ring finger when he reached under the dashboard of a '48 Chevy he was rodding.  Shorted at the radio power input.  It was REALLY ugly afterwards for the remainder of his life.

He worked the last 20 years of his profession as the chief electrician and head of maintenance at the reactor at Sandia National Labs.

Even so, I can say that he would not believe that proper cables, greater current capacity, connectors or any of the things we take for granted as true.

I wish I could have showed him  :(. It would have stoked a fire in the Oldster's brain pan.

Miss you, Pop.  We'll talk, later :thumb:

Well guys, I got my hands on a little plug and play item and after doing just that, Can't imagine how we could have so many pages of write up on it. How many ways can you say something is effing awesome. Sources to DIGI to Majic to wall, oh my.
Can't say everything gained is from DIGI cause opened a space on the Majic for amp. Absolutely got improvement in the system.

Thanks Dave
