New Magico Speaker Break-in Question

@decooney Many thanks for your thoughtful response. My A5s are powered by McIntosh MC611s. These are mono amplifiers that output 600 watts are 8, 4, and 2 ohms. Consequently, I don’t think that my amplification is the cause of my near-term concern.

@ all  I am impressed by, and most appreciative of, the thoughtfulness of all who have taken the time to respond to my inquiry. I would like to add that I also bought Magico's ACC as my new center channel speaker. Last night, my wife and I watched episodes of Matlock and Reaper. We always have subtitles engaged because it is hard for us to grasp all the dialogue. Afterwards, both of us were surprised that we weren't reading the subtitles. The ACC reproduced the dialogue so clearly that we were able to understand everything said. It was remarkable! I strongly recommend the Magico ACC as a center channel speaker.

@jmeyers -- I hope re-positioning or time help to tame the speakers.

Apologies for breaking in, but your post gave me pause as I am on the verge of upgrading from A3s to A5s. The A5s will be  dealer demos from out of state with roughly 200 hrs. My amp is a  pre-owned T+A PA 3100 HV.

 I have pretty old ears that have lost a lot of HF detection, yet ironically have become sensitive to bright equipment.   Overall I really like the A3s and while they do not come across as too bright, I'm concerned that the more revealing A5s could.

I have not heard the A5s and kind of assumed that if I like the A3s, I will really like the A5s. 

@hilde45 I'm surprised to hear your thoughts on the Salks. I have Song 3 and it's one of the pieces of gear I would never sell. Perfect clarity but not fatiguing to me. Different tweeter though. I haven't heard that complaint much about Salk. Somewhat incidental as they no longer exist.

Congrats on your new Magicos.  I've heard the Magico S5 MkII several times, and was always super impressed. No inherent brightness to speak of.  Once the woofers get fully flexed, bass should extend and improve, and may even balance out the treble somewhat.    New caps of this caliber can be pretty sibilant for a while, but should come around. 

In November I installed a couple of new caps in my preamp, then tried to evaluate some DACs....everything sounded shrill.  I thought the new DACs were awful, then remember the new caps.  Within a couple of weeks they got much clearer, and opened right up....no more shrillness.  The DACs were fine.

Best of luck with your acquisition

For sure, and you’ve checked that box and then some, very nice! Just a few days ago a known celeb’s system showed up on a video with similar Magicos, and the larger Mc amps. Interesting.

The other specific thing I can think of is those same caps in the speaker crossovers. I’ve used multiple variations of those same Mundorfs in different components and wow, they can take a looooooong time to form, break in, settle in. Some silver-over-copper and certain OCC cables can have a tipped up sound too fwiw. Curious how it sounds after your 250hrs of play time. Enjoy your system, have fun!
