And yet on a variety of Sony cd's the SQ emblem is quite prevalent , and likewise and more importantly so do ALL of the latest Sony multichannel quad SACD'S.
So you see , forgive me but I find your statement rather puzzling .

unsure: )
Fwiw , Sony doesn't seem to have any difficulty with SQ reissues . Both cd and SACD.
The last known SQ encoded recording was back in approximately 1985 with the Buddy Rich-King St. set , also the last known SQ decoders were released by Aphex in 85, 86 , and I believe 87.
Personally , I think it's now in the public domain and if not , well then WHO do you think owns the rights to use both the SQ encode and the SQ matrix emblems ??

As to seeing a complete list of Sony SQ titles , on cd , I too would love to see that quad listing as I'm sure most of us on QQ would concur .
