Listening Room or Components or my ears?

@OP - two definite problems and one potential one. Your Focals are bright sounding and the Rogue amp leans in the same direction - put together its a case of negative synergy. But the speakers are the more problematic of the pair. The room sounds like it would benefit from acoustic treatment. Since that is cheaper than changing speakers, it should be your first port of call. But don't be surprised if you have to look at the equipment once the room is sorted. But at least you will have a neutral sounding space to work with.

My older Wilson speakers have the Focal 1" inverted titanium-coated tweeters.   They have a bad reputation for harsh highs.   When I first got them, I concurred.   Not anymore.  Now, they sound sublime.   Zero fatigue.   The solution was cleaning up the AC power - with special attention to the digital components.   

All of the above suggestions about the room, room treatments, speaker placement, speaker toe-in are correct - as is clean power.   It takes a fair amount of tweaking to properly dial-in good SQ.    The distance between the speakers is based on several factors.  If they’re too far apart, the soundstage becomes defocused & delayered - a vocalist sounds like their mouth is 5 ft wide.

Here are assorted discussions.

Reduce all toe-in. Have speakers facing straight ahead. Worked like a charm for my B&W 803 D3s.

Facing speakers almost straight ahead does turn down higher frequencies and especially if the speakers are not far apart from each other. No toe in toward the main listener position.

Good Day

Thanks to all for helpful comments and suggestions. Much appreciated.

You've given me lots to think about and explore.
