New Magico Speaker Break-in Question

NEW Speakers and their initial stiff driver rubber or foam surrounds will loosen up, the capacitors inside all settle in with some good play time on them. Pretty standard for new stuff. Used stuff, no need to wonder or worry just play it and enjoy.  

New stiff [overly rigid] coiled up multi-stranded copper cables with rigid dielectrics inside, especially those sitting tightly coiled up in boxes for six months on a shelf, initial static electricity release, all well known and measurable parameters that change with some with a little play time. Compare sound at 1 and again 14-21 days. If you can't hear any difference, even better - no need to buy more gear. 

@jmeyers You can try one or more Akiko Audio Tuning sticks with your electronics. To my ears and in my system, they tame the edge of the high frequencies.

@jmeyers --  How are things with the new A5s?

For those who are interested, here is an update. The best news is that, after about 100 hours of breaking in, the A5s are beginning to sound noticeably better. One of my most challenging demo tracks is the 176/24 version of the famous "Take Five" piece. At this point, the drum play sounds terrific, as does the piano. The one aspect that still isn’t as good as it ought to be is the tenor (or, maybe alto) sax. The loudest notes still have a bit of harshness to them that is not present in real life. [Recently, I went to a jazz club primarily to hear live playing to both types of sax. Even when played at "full volume", I did not hear that edge of harshness present on the recording -- of which, thanks to Tidal and Qobuz, as well as my CD, I have lots of versions.] Another thing about the A5s is that, despite their three 9" woofers, bass output really falls off a cliff. Playing Stereophile’s original test CD, here are the db levels in my closed 22x21x16 media room at various Hzs: 160 Hz - 63 dB; 125 Hz - 62 db; 100 Hz -53 db; 80 Hz - 48 db; 63 Hz - 48 db; 50Hz - 42 db; 40 Hz - 36 db; 31.5 Hz - 32 db; 25 Hz - 30 db; 20 Hz - 32 db. Fortunately, I own two of the new SVS SB17 subwoofers that have six separate parametric equalizer bands. Integrating them with the A5s, I have a flat (+/- 2db) frequency response (at 70 db) all the way down to 31.5 Hz, and then down 2 db at 25 Hz, and down another 1db at 20 Hz. This integration took me around six to seven hours over two days!

Responding to other comments made recently, my Wireworld Silver Eclipse speaker cables are silver over copper, in an unusual (and patented) strand size and configuration. Previously, I found them to be incredibly neutral. As for Akiko Audio Tuning sticks, I certainly will look into them, and I thank classic8 for the suggestion.
