Nice, nice, very nice.
I have never seen the insides of most of these famous places.
It seems most of the mastering rooms are set up for near field listening and even the Abby Road Penthouse is surrounded by five B&W 800Ds in near field. However, the front three big speakers are just about touching the wall behind them... It would be ultimate to have a listen in the room and I am sure it will produce proper high fidelity recorded in the source material. However, I wonder how it would do with audiophile nuances such as depth and imaging, etc. we often seek in a system.
