Thanks for all the well thought out responses. I appreciate that. I have learned a few things to move forward;
1. My room isn't going to change much any time soon.
2. I need to get a better grip on just what is happening, how are certain frequencies bouncing around and what about the profile that I hear am i finding unpleasant.
3. If I add an EQ, it will likely be a Schiit product.
4. There is a wide range of perspective about sound/musicand it's reproduction in our homes. I fall into the "if it sounds good - listen" camp. I know that I will break a few laws going forward.
So with that in mind - I spent the weekend rearranging my room a bit. I can't change the bones of the space or really add much treatment so I did an unconventional thing and moved my gear so it is now in a corner at 45 degrees rather than at one end of the room. This allowed my to space my (floorstanding) speakers farther apart and a bit more into the room. Also gave me I bit more flexibility with my listening chair. I now form a better triangle and aim the speakers about a yard behind my head.
This has really helped several things. I don't notice many recordings to sound harsh as much, the soundstage is better, and I can recline my chair!
Having more room across has allowed my to put my old 2 channel speakers into my 5.2 video set-up as fronts.
Next step is to try and get a better picture of the sound profile and decide on what EQ may be needed.
I'll check back in and let you know when I wrap up...thanks for helping out.
