Who's to say that the wave propagation rate of the age-compromised material isn't sub-optimal as a result of it's being stored beyond the Zodiacally indicatorial parameters of expiratorial storage expectations? Defunctus Expectatum may have already set in to a degree that even a government committee can't effectively obfuscate. How would you know what sort of acoustic dysfunction you were introducing into an otherwise potentially nominally perfect system? You might have actually made something less good by the cavalier use of this suspect material. Shame on you. Go to your room! Ron N
