New Magico Speaker Break-in Question

Congrats on the new speakers. I jumped from Revel to Focal Scala Utopia, which have a beryllium tweeter. I believe there are some similarities between the Magico and Focal speakers in that both are going to be very revealing of the electronics and the track. They will faithfully reproduce the signal you give them. In contrast, long ago I had SF bookshelf speakers and regardless the electronics, they reproduced a smooth, warm sound - good for some music, but not for other types.

Once you break them in, I think you need to decide if you want to go down the path of adjusting your electronics or swapping speakers. Magico are very backordered so you can easily sell them. I have been upgrading all my electronics and the high mids and highs are much better, but there are still a few tracks that are troubling to me. I have the same issue on other speakers so some of what you hear may be your ears or room. I want to blame my benchmark dac, but it could be the tweeters.

My advice is to let them break in and consider your electronics and room. Reducing toe in help me as well and I prefer a wider sound anyway. Be aware that you may be upping the volume to get the bass to hit harder, but then adding too much high frequency at the higher volume.  Also, try to embrace the highs and the details. There are two sides to every coin and that level of detail and reveal is addicting and adds so much to the soundstage and nuances of all instruments and voices. IMO, each system excels in certain areas, but also has drawbacks. If you like all types of music, then an all-around system may have a few rough spots but mostly hits home runs across all genres - I think this will be your system. I listen to everything from slow soft vocals and instruments to techno club music. So embrace the highs and admire them, and don’t ignore or wish them away. I listen into the high mids and highs and am amazed at the clarity and detail. I won’t have these speakers forever so while I do I appreciate their characteristics. It takes time to adjust to new speakers.

Step 1: Set them up facing straight ahead (i.e. 30 degrees off axis). If brightness still there...

Step 2: Get a 31-band dBX dual mono EQ  or other EQ and try to EQ out the offending frequency band. If brightness still there...

Step 3: Pack them up and return or sell because no amount of gear changes, cable changes, etc will make up for a speaker's native balance. Speakers either work for your listening preferences or they don't!

+1 @bojack Hopefully step 1 works for the OP. That is exactly what I did and it worked for me (my post above, step 1 only).

Honest question... does a speaker such as the Magico create a harshness, or does it reproduce a harsh tone being sent to it with more clarity? I mean, do the drivers distort, etc and create the harshness?

My previous preamp sounded really good most of the time, but many songs sounded sibilant.  I blamed it on the recordings. When I was forced to get a new preamp, I still had excellent detail, but the sibilance was gone.  Upgrading my dac also helped. 

I'm not saying that this is the OP's problem.  I'm not familiar with his gear.

I had exactly the same experience when upgraded SF Venere to SF Sonetto III, shrieking sound. I played them, facing each other and covered with heavy comforter, for four days using "Irrational but Efficacious" CD by Ayre. The results were obvious, shriekiness was almost gone. All together, after about 200 to 250 hours the sweet SF sound settled in. Be patient!
