This first time I heard height reproduced through a hi-fi system was when I played Boult's recording of Holst's The Planets (EMI ASD 2301) on a Thorens TD-125 Mk.2/SME 3009/Decca Blue pickup turntable, feeding pair of Magneplanar Tympani T-I's bi-amped with ARC tube amps. Way, way at the rear of the hall (which itself could be heard) I could "see" the percussion instruments (particularly the triangle), raised on a podium above the instruments in front of them. I didn't yet know symphony orchestras were so situated, and had no expectation to hear that sound. Yet I did.
Soundstage and image height, does it exist?
On another site, there is a discussion on soundstage, and there are a few people clamming, that, since there is no vertical information encoded on stereo recordings, that soundstage height does not actually exist. It is a product of our minds filling in missing information.
Are they correct?
Please explain your position, with as much technical details as you feel needed.
