Warm romantic & detailed

Vu of Deja Vu in Wash DC (a major Harbeth dealer) maintains the 40.2's need a minimum of 2' to the sides and really 3' behind them.  I don't have experience with 40.1's but it seems likely they might need more.  My 40.2's sound "just right" to me, neither too syrupy nor too incisive.

I am very sensitive to the problem you have and one thing that I’ve settled on is NO metal dome tweeters. I do much better with soft dome tweeters or a well controlled EMIT.
That said, I just bought a pair of Dynaudio Evoke 20 speakers and I’m in love. They are smooth and very listenable. Gone is the edge that annoyed me with my previous less expensive but well reviewed speakers. While I am limited to a book shelf speaker because of room confines. They also make floor standing 30 and a Evoke 50 models. I believe the whole line has the sound that I now like but maybe you can find some reviews. The top of the line floor stander Evoke 50 is $5k a pair and the Evoke 30 about $3500 a pair. While my Evoke 20s go for $2200, the addition of a couple small T/i REL subs would go a long way toward replicating the floor standers bottom end dynamic, bringing the total investment to around $3500 or $4k depending on the sub. If I could use a floor standers I’d be hard at work justifying the purchase of a pair of 50s. I also believe they make a center channel speaker for inclusion in AV setups.

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.
