I feel for you Lalitk, how frustrating. Getting speakers like that should be so enjoyable, quite a momentous occasion, as material acquisitions go. Getting one bad pair is frustrating enough, but two bad pairs? You are a very patient man.
I wonder if Zd542 isn't onto something, about the possibility of them being demos. I've also purchased multiple pairs of B&W speakers new, and I've never seen so much as a fingerprint on them. Quality control has always been beyond reproach, in my own personal experience. Two blemished pairs of 800-level speakers in a row seems too odd to be random coincidence.
