Query: Beware MONO!

I'd be tickled if this box set was in stereo or had a couple of mono cuts only because they were the better version. But the 1'st CD only plays out of the left channel in mono!? If a company is going to do a mono recording, for heavens sake, have it coming out of both channels!! I duplicated the process in several different players, but was absolutely bummed when I eagerly put in my reference system for the first time & heard that!! Buyer beware.
