There are some who believe that even with the very best of recordings, the best loudspeakers with the quietest cabinets, the best rooms acoustically speaking, 2 channel audio is at best only able to give limited amount of realism/soundstage depth.
Some, like the physicist/audiophile Dr Edgar Choueri, argue that spatial audio could be the best way forward when it comes to sonically reproduced realism.
After hearing him speak on the Audioholics YouTube channel, I'm tending to agree with him.
