Does anyone here have this SACD? When the recording was bundled into the Percussions de Strasbourg 50th Anniversary box it was in Red Book CD format only. From the one fairly detailed review I can find (amazon.fr) the original recording appears to have been in 2 channel stereo which was beefed up to a semblance of 5.1 surround using IRCAM facilities. Can anyone confirm or deny this authoritatively please? I gather there is a detailed description of the process employed in the SACD's booklet.
