Humprof do you have the twofer cd that also has Antelope Freeway ? I had read that that one was QS encoded and they did things like set out microphones outside to capture road noise.
If you have listened to it how does it decode?
Interesting...I didn't think Antelope Freeway was actually QS-encoded, though it does "upmix" nicely with the SurroundMaster in Involve mode. Let us know if you hear a QS decode!
