Warm romantic & detailed

Your Lumin T2 may be your problem. Had one in my system for a couple of weeks. Very detailed , but definitely can definitely get fatiguing over time. Look for a Dac with a AKM chipset or similar Sonics. You will lose a touch of detail but you will enjoy your system more 

@jeffinnh76 My room is 14’ x 26’ with 7.5’ ceilings. I had no problem with the 40.1 in my room and I know of others with comparable or smaller rooms that had success with 40.1’s. If your room is well treated, I’m confident you will be fine.

With that being said, everyone hears differently. I was almost ready to give up on my new (to me) 40.2 Anni’s for being too strident (in the same room and with the same electronics used for my 40.1’s), but I just did an overhaul of my room treatments, spending over $2K on GIK absorption and diffusion panels and now everything sounds right to me... a huge relief. To my ears the 40.1 is more romantic and warmer than the 40.2 Anni’s, but now that my room is properly treated, I’m hearing warmth AND detail in my 40.2’s that others in this chain have experienced.

As long as your room is treated properly, you can’t go wrong with either speaker.

Note:  My system pics have not been updated to show the overhaul of room treatments.   Best $2K I've spent.

Prior to my Lumin T2 the brightness / fatigue was actually worse. Prior Dac's were Topping D90, Bluesound Node 2, and if course the Dac in my mac. The Lumin takes a very long time to break in, for me 3 straight weeks of playing. 

There are too many reply’s to check for any Von Schweikert recommendations. I had the same problem with the top end, and went through a couple of different speakers before I found my Von Schweikert VR 33’s.  Their sound is big, full, lush and romantic. Broad sound stage and good bass. Nice highs and no listening fatigue. They have quite a few different models, and cover the gamut price wise. My VR33’s were at the bottom of their price range at $3700, but have the quintessential Von Schweikert sound. Price wise they go up from there. 

I do not think the Focal tweeter is repairable (in the way that it sounds, ha). That is the Focal house sound I have found over many, many years of hearing them. Great demo speakers. You either love it or try to get used to it.
Changing electronics to modify speaker sound when the basic sound is offensive won't work, imo. Neither will DSP. It's the house sound; love it or leave it.
There were great speakers mentioned and having owned Scansonic MB2.5s for a couple years along with Dynaudio Sapphires, I will say that the Borresen designed, sealed ribbon tweeter bested the Esotar II in sonic purity and wonderful clarity, never-ever harsh.
Joseph Audio are wonderful and pure of tone. Sonus Faber may be something well worth auditioning and I've heard many Spendors and Harbeths at shows that were superb loudspeakers and not harsh.
I'd be looking at nice models with ribbons, sealed, folded, etc, and Heil Motion type tweeters for clarity without stridency. I may be forgetting other types. But if a dome, I want silk.  (B&W Diamonds fry my ears!)  Good luck.
