Three Aurios MIBs left over from a past life of audio debauchery currently undergird the Dell laptop that serves as my bedroom system's program source. I've been listening-testing over the last couple of days to determine if they should remain or, as one alternative, be replaced by a spare 2"-thick maple butcher block I have on hand. I've yet to listen critically to the latter configuration, so it'll be at least a few more days before I decide which way the cookie crumbles.
