Re mono in the next room or down the hall, I agree, as I indicated on Page 1, BUT its not the same when you listen to mono in the same room from your sweet seat.
With a grand piano in an enclosed space even though the source of the direct sounds are obvious the resonances created by the room surfaces in a live performance will be absent in mono - you will have a small central image and no sense of the acoustic.
Thats why 'in the next room' works so well, IMHO, you get both the 'mono' sound and some room resonance sounds without having to sit in front of the speakers and be distracted by less than the sound of a performance from a prospective that you prefer.
