You’re right. B is the reissue. So much for a blind test but a solid effort nonetheless.
I would like to submit these 2 opposing options as what a solid effort is - notice that both show/claim there IS a difference:
option A : WE ARE CLEARLY SELLING BOTH (an obvious A/B jack out - jack in, right in front of the media?!)
option B : WE ARE OBVIOUSLY NOT SELLING EITHER (not an obvious A/B same settings signal chain - difference might be a bit less obvious than in option A but it surely is not deliberately adjusted to be minimal)
