I spent last evening (Sunday) listening to a broad selection of full symphonic classical music, everything from Joaquin Rodrigo's Concerto de Andaluz and Fantasia para un Gentilhombre to Aaron Copland's Applachian Spring, and ER is performing wonderfully. My ER had about 24 hours of burn-in on it at that point in time.
There is an accurate and mellifluous presentation of hall ambience, spaciousness, depth, width, and instrumental imaging, separation. and definition. Timpani produce incredible dynamics and scale, and the individual instrumental timbres are detailed and lifelike. I can hear and place individual instruments at the back of the orchestra with respect to placement, volume (loudness), texture and scale. The listening ease that ER imparts makes it enjoyable to listening to a range of different mic-ing, recording, and mastering for the various performances.
