You may like the sound in the balcony and from your speakers, but this is a bit of an apples/oranges comparison. Depending on the music, Telarc recordings employ a mix of close mikes and distant hall mikes to capture hall ambience. Some recordings use several spaced omni mikes at the front of the stage. The omnis reveal more hall ambience and less specificity of instrument placement than cardioid mikes. The net perspective of the Telarc is about row 10, which is much closer than balcony perspective. This correlates with my experience auditioning large stat panels such as Martin Logan, SoundLab. Bass is powerful from the large panel area, but the large panel area radiates sound in a multitude of directions which causes high freq time smear and rolloff due to different time arrivals from all points on the panel.
Even a balcony lover like mahler123 found that a recent concert of a Shostakovich violin concerto showed less detail in the balcony than his experience at home with an old recording of Oistrakh with Mitropoulos conducting the NYP. If you want to judge the overall accuracy of your audio system, experiment with rows 5-15 and compare to the Telarc recording, or sit much closer near the stage for Mercury Living Presence recordings, or my favorite 1967 Turnabout LP of Rachmaninoff Symphonic Dances with Donald Johanos conducting the Dallas Symphony. A great companion Turnabout LP from 1967 is Copland, Fanfare for the Common Man, and Rodeo. Very dynamic in your face Fanfare with brass and percussion, which I like better than a much more laid back audiophile recording of Fanfare on either Telarc or Reference Recordings (I forgot which). Some pieces are appropriate for laid back recordings, like subtle Debussy, but Fanfare deserves more immediacy.
For accuracy, the original Quad 57 electrostatic is tops, although it is deficient in bass and loud dynamics.
