After owning a number of McIntosh Amps and PreAmps and unpacking them. And if you had original McIntosh packing, I say in all confidence that the glass could not be broken unless (A)there was a hole through both boxes aligning with the point of impact or (B)the boxes showed unmistakable evidence of damage suffered from impact of dropping, crushing or abuse.
If this buyer waited more than 1 hour after opening the box to alert you to the damage, then he had to have done it during unpacking. McIntosh designs their packing to be overly protective to a fault.
What does this guy want you to do? Buy it back? Pay for the repair? Reduce Price?
Has he sent you a picture of the broken glass?
Proceed with caution.
