I would have guessed equipment compatibility. The Magico A5 presents a difficult load. Your virtual system list your stereo amps as MAC 611 Monoblocks that can well handle the 2ohm dips in the bass. Therefore, it should not be a compatibility issue IMHO. The A5 is a very detailed and clear modern speaker. The bass presentation is much tighter than the Revel Studio. The Revel house sound is detailed and clear in its own right, but may sound romantically thicker in the bass and mid bass to my ears. You may be reacting to the differences in house sound. However, some have published Magicos need 300-500 hours of break in. I recommend you evaluate the sound as they break in over that time period.
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?
