Help. System sounds thin and bright or harsh

Cymivka, thanks for the extra info.

Not familiar with the sound of your DAC. I wouldn't consider the Oppo built in as warm. Sabre chips can be a little relentless. Good designers can overcome this  by not using all of Sabre's baked in digital filters and settings. My Ayre uses a Sabre chip and sounds nothing like the Oppo. Oppo seems to make a good transport. 

It is easy to check the AC power. A VOM can be purchased for around $20. They are even available at places like wally world. Just set dial to AC and insert a probe into each flat hole of the wall receptacle. Warning - don't touch the metal prongs. If you aren't comfortable doing this get someone else to help. 

Good luck,

thanks for the AC check advice.  I can easily go the VOM route,  Listened last night after a wine or two and the system actually sounded "choked" to me at higher volume

I’m not sure if someone mentioned it, but subs always help. Harbeths are nice but may not handle the new room. 2 Rel s510’s would do the trick. That’s the route I’m heading as well. Sitting in front in listening chair, my system is awesome. In the kitchen area 15 feet away, missing just a bit. Enter the subs, which I’ve always had but not in the new system. It’s my next purchase. 

What power cables are you using. In my system stock power cords made it sound harsh and bright and thin, lot of metallic sounding highs. Replacing with Pangea Ac14se mk2 eliminated emi and made music.
