I spend a lot of time at Barbican, Royal festival Hall, and Wigmore Hall in London. It is precisely for full symphony orchestra and for reproducing, say the brass section in Scheherezade that I experienced in the Barbican that I preferred the Auro 3d Multichannel. That, Bach chorals, and opera duets. For piano box speakers have inherent limitations due to cabinets and I prefer a 2-ch Analysis Audio (the Soundlabs should do the same as the AA). For other baroque stuff, and Cecilia Bartoli arias, it was very good, but not that much better over a good 2-ch system. All that I heard on Auro was upmixed from 2-channel
