recommendation for speaker wire to soften the highs if possible

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?.

. Richard Gray power conditioners are warm and will soften up the highs. Model 400 are below $300 on eBay.
. Vintage MIT MH-750 Plus speaker cables (white color) on eBay for around $300 are (very) polite, low white noise and really soften up the highs.
. Vintage Goertz speaker cables can drastically cut off (some) the highs completely.
*** Speaker cables will/may change characteristic of your system a lot so I’d suggest Richard Gray power conditioner. It mated very well with My Belles 150 Hotshot years ago. I then moved on up to Dave’s Reference a150 v2 and couldn’t be happier.
