Hey grannyring,
Between two old timers who have been at this a long time, we will agree to disagree regarding the DI's being, " just lean, on the forward/analytical side of things". I think they are dead on neutral and not in anyway analytical, that's way its so important what you drive them with.
Historically, I have disliked very much many of the Magico/YG Acoustic/Wilson speakers because I found them to be analytical and did "everything right" but make music, sound like music.
My reference of five years was the Cello's, which I believe are very close to the overall sonic signature of the AZ's, which I loved having in my system. Both the Cello's and Crescendo's are a smidgen "warm/sweet" which I like very much and I do not found them fat or euphonic in their performance. However, when I got the DI's tuned in both in room placement and what to drive them with I got all the musicality/beauty of my Cello's plus "aliveness" dynamics and speed with no edge at all and could not go back to my reference speakers any more with out missing what the DI's were providing.
A final note, I still have not heard a system, and I have heard many indeed, that I can really say that I thought was great that uses a room correction device. I totally accept that they can help greatly to overcome shortcomings in the acoustic space, and it might be significantly better then nothing at all in certain rooms, however they still do something I find slightly "artificial" to the music to my ears. Regardless, if its correction done to OB speaker designs, Legacy's device for their speakers, or general room correction it just does not "sound" like a great natural acoustic space to me.
