recommendation for speaker wire to soften the highs if possible

I agree that Dueland cable might tame the harshness you are hearing.  I don't see a preamp in your system, and if you are on a tight budget, I  would heartily advocate hearing a Schiit Freya preamp with the tubes upgraded to Shaguan 6SN7 tubes and you will get taste of audio splendor.  The next and final step would be a Don Sachs preamp. :-) Consider room treatments as well.  

Get Granny to make a Dueland set and jumpers. You will not regret it!

Thanks for all the great advice. I do have carpet in the room and my monster cables are Powerline plus 3. I also have my amp and oppo plugged into panamax MR4300.My speakers are 8 feet apart and on stands at 26 inch. They are about a foot away from the wall. I have furniture in the room as well. The room and my wife :) limit an ideal setup. it sounds like this weekend I should move things around to see if it makes a difference. If it does not make a big difference I think these are the suggestions if I’m reading correctly.

1. .Replace wires with Dueland wires, or Signalcable or supra wires.
2. .Replace interconnect cables.
3. . Have Grannyring’s build some wires
4. . Down the road add a pre amp (schiit or other tube)
5. . * Ask local dealer to loan out and try cables. I like this option and I like the local dealer but price differs greatly.

Thanks again for all the help

How about acoustic panels behind the speakers? Experiment first with blankets/ pillows to see if they make a diff.
Check out GIK Acoustics, they make beautiful "art panels"

Could it be the tweeter and how you perceive hf sound?. Did you try a different speaker?.
