I think it's neat that Oppo sent it, but now I understand more about why they sent it. It appears the commercial version of the Spears & Munsil BD comes with the blue lenses. But those of us in the EAP, at least, did not get the lenses with the disk packed with the BDP-83.

The AIX disk, which in part is a sampler designed to sell AIX recordings, uses the BDP-83 in illustrations accompanying the calibration stuff.
