I came across two Vocalion Jazz SACD titles at HRAudio. They list them both as multichannel but I cannot verify that.
The two titles are http://hraudio.net/showmusic.php?title=1067&showall=1 and http://hraudio.net/showmusic.php?title=774.
I did order the latter title and will report on the performance/SQ once I receive it.
Some additional info from the Dutton Vocalion website: http://www.duttonvocalion.co.uk/proddetail.php?prod=CDSA6815 and http://www.duttonvocalion.co.uk/proddetail.php?prod=CDSA4801.
No mention of multichannel but I'm always looking for hi res jazz recordings.
Addenda: A copy of the email I sent today to Dutton Vocalion: "I am one of 10,000 members of a US based Quadraphonic website called QuadraphonicQuad forum and we are VERY excited about your newly announced listing of 6 QUAD titles from the RCA catalogue and wonder if you would take suggestions for further releases in the SACD QUAD format. We invite you to visit our website and introduce yourselves and would like VERY much to chat with you. Many thanks in advance."
I would strongly urge other interested parties to do the same! Can't hurt. http://www.duttonvocalion.co.uk/contact.php
Great idea to send an email about future releases...I'm sending one NOW
