Lots of good comments here.
Nonoise-The next round of auditioning will focus on chamber music. When I bought my Maggies, I used orchestral, choral, piano, chamber, every type I have, in order to get the best general purpose speaker. As far as recordings, I have a half a dozen Beethoven cycles, two Mozart cycles, Haydn on a viariety of labels, with numerous repeats on certain pieces, 3 Shostakovich cycles, a good mixture of Brahms, Dvorak, Bartok, Britten, the list goes on--hundreds of recordings on numerous labels by a variety of ensembles. I can't think of a single recording that does what I am looking for.
Charles1dad- I am very interested in the Coincident stuff. I need to hear some of their gear.
Rok2id, large scale works aren't perfect, its just that after extensive auditioning, the Maggies were the best at orchestral stuff at anything close to the price. Im also not surprised they can be quite convincing on a well recorded soloist with a central image. That is a much easier problem. I think Frogmans comments lead me to know where to start. With a live performance, seated center front, with my eyes closed. String quartets are a tough problem both for recording and play back.
