New dedicated line & outlets sound worse, not better- HELP!

About 3 weeks ago I installed a new dedicated power line from my breaker box to the outlets for my stereo set-up.  I used 10 gauge Romex, a new breaker in the panel, and also installed two new Porter Port cryo'd outlets.

My system is comprised of the following:
Gallo Strada speakers
M&K MX-80 sub
Parasound A23 amp
Consonance Cyber 222 line stage pre
MHDT Stockholm 2 DAC
Audio Philleo converter & Pure Power module
Clear Day double shotgun speaker cables
Silnote Epirus USB cable
Silnote Morpheus IC from DAC
Audience PowerChord from DAC
spiked maple stands for pre and amp

So my concern is that my system sounded just about perfect prior to the installation of the dedicated line and outlets- very clean, open, and detailed, yet also a musical and relaxed sounding. I figured the new dedicated line and outlets would just bring more of all of the good things I was hearing.

Instead, following it's installation, everything sounds a bit edgy and fatiguing to my ears. Soundstage depth and separation are improved, as well as bandwidth, but I literally cannot listen for more than 30 minutes before I get irritated. The treble seems too aggressive, which I'm very sensitive to. And there seems to be a slight veil over everything- just not as open as before.
Do I need to just be patient with break-in of the line and outlets? I've heard it can take a month or more for things to settle down. What are others experience after installing a new line and/or outlets?
Any insights or possible issues I might have overlooked are much appreciated!

I'm encouraged with responses. 
I did not burn in the Porter Ports prior to installation.
I'm currently running fans on two of the outlets and I have kept the Parasound A23 on day and night. 
At this point it's probably just a matter of patience. 
I will update again in a week or so and share impressions. Hopefully there will be some improvements!

I would suggest trying a Synergistic Research Black A/C wall outlet with your new circuit. I found it to give me more detail and yet at the same time be less fatiguing. They will be fun to compare to the Porter outlets. They are sold with a 30 day return policy.

You can also improve your system's performance by using a Jim Hagerman FryCorder. This device conditions the wire in the wall all the way back to the power company's transformer. It works.

A couple pieces of advice I got before having my dedicated lines installed was to run all lines from the same leg of the breaker box to avoid ground loops and to not have the lines share a neutral bus.  Not sure how many lines you ran or if this is helpful in your situation, but fwiw.

The outlet looks like it is made by Pass & Seymour.

Is the back strap made from galvanized Steel on the Synergistic Black AC outlet?

It sure looks like galvanized steel.

Maybe .....just maybe, you are actually hearing what your system is made up of due to an improved current . But burn in time for outlets and Romex wire ...really ?
