Open Baffle Experience
@mwatsme The recordings were made by Audiogon member @shkong78 at the Pacific Audio Show. I don't know what he used to make them.  To me the Spatials sound very good and are at the very least competitive with the Voxativs.  
Classical piano solo—Your one favorite performance and recording
