I own a pair of A-5's in my second system. First most high end speakers are "broken-in" at the factor. Next I've not found any harshness in the tweeter. I think as others have said they are more revealing to downstream components. I would look to your DAC. Interesting you found they lacked bass. I do not experience that. It may be that your just "used" to subs in your system that have boosted the low end too much. These are truly great speakers. Congrats
New Magico Speaker Break-in Question
This afternoon, I received my new Magico A5s, which replaced Revel Studios that I have owned for more than 20 years. The A5s are definitely more clear, have superior imaging and provide at least equal soundstaging. The bass is tighter, but, with three 9" woofers, I am surprised that it doesn't go very deep at all (fortunately, I have two SVS SB17-Ultra subwoofers that will easily take care of that shortcoming).
However, there is one aspect of these A5's performance that I find a bit disquieting and the reason for this post. The treble in the 2KHz to 5KHz seems to be a little [what I'll call] shrieking; it is somewhat uncomfortable to listen to for an extended time. I know that this loudspeaker uses a beryllium tweeter, and I have never had a speaker before that employed one. Perhaps, its tonality is what I am reacting to .
And so, my question. I have read that it takes 250+ hours for the A5s to break-in and become the speaker that Mr. Wolf and his colleagues intended. As part of that break-in, will the tweeter also blossom and become easier to listen to?
