"My concern would be if other units from different dates
were built with metal top and sides, and if so why?"
Exactly, Attila. I held my unit under a bit more scrutiny than normal due to its B-stock status. As such, the reason for the question about its top plastic-like material vs. what I was expecting - an aluminum top. It is good to know that the top and sides of yours seems the same as mine.
My concern was that of misrepresention of the product (i.e. not just B-stock but exterior (and possibly interior) changes), not particulary about the sound output.
Please do post your findings.
