@havocman , I have only listened to S and Q series speakers so I can not comment about A series.
Build quality is easy to determine. You can see it, even in a photograph to an extent. Sonic quality is another issue. You can not rely on what anyone tells you and that goes for my opinion also. I can't listen to the speaker in your room. When you say "too bright", that is an amplitude issue. Amplitude response can change just by moving the speaker a foot! What does "too bright" mean. Is the treble too loud or is the midrange too soft? Maybe the listener is used to listening to a system that is too dull. Trying to say any type of driver sounds like such and such is incorrect. There are too many ways to change amplitude from the room, to the crossover, to the type of amp being used, to the listener. Beryllium tweeters can be constructed to play extremely loud with very low distortion for a dynamic driver.
Lastly, with high resolution digital EQ capability, resolution in 1 Hz increments I can make any speaker sound like anything. With a modern digital processor amplitude response is completely plastic and can be tuned in the environment the speaker is going to live in.
I can not make any loudspeaker image correctly. There are very few systems that can. Most of use have never heard a system that does. That includes all those fanboys with the flowery descriptions of "wide and deep" soundstages. The sound stage depends on the recording. For the first 17 years of my audiophile life I had never heard a system that imaged a the state of the art. When I did my jaw must have dropped three feet and that moment is burned into my head forever. Next was creating a system for myself that could do the same thing. That took another 15 years or so, another $150,000 and hours and hours of screwing around and learning what it was that made a system perform at that level. On the bright side you do not have to spend a million dollars to get there. Excluding the room and at current prices you can probably get reasonably close for $100,000 and all the way there for $200,000. Anything more than that I consider to be "luxury" audio just for bragging rights.
