Received my Spinners V2 Bluray yesterday - so....
To IDENTIFY the difference - on the bluray, look carefully at the print around the spindle hole (almost all CDs, DVDs, and BDs have printing here.....and if you compare it to the V1 bluray - you'll find a V2 code after the catalog/serial number info.
From the V2 BD, I extracted all channels to each track and compared them to the extracted channels of the V1 BD - and you can clearly see that LEFT FRONT channel fixed....other folks might do this and post these screenshots...
If you just compare by LISTENING to each BD, if you have a sensitive ear - you'll hear the difference....
Way back, when V1 was released and I listened - I THOUGHT I noticed that FRONT LEFT channel down....as like many that already had a QUAD transfer someone released from a CD4 source noticed, too.
In any case, I love these Quadio releases as they sound so much clearer then the secondary transfers I and others located over the years before...
I hope to see more!
