On vacation and back home in Beijing. Today I was lucky enough to have listened to a large number of universal pieces of the CIEMs at the Beijing Audiophile Exhibition, including that of the UERR. I would say that UE achieved a subtle balance on it, making it being reference yet pleasant to the ears as well. Considering it contains only 3 drivers per side, the UERR is indeed a masterpiece. However, as I may not be able to deliver the ear impressions on time, I'm afraid I have to let this drop go.
