Ebm's response would apply to me as well if the gear were still in use. Well, at least I think my stereo loves me.
Oldest piece of gear you own
I will start - Pass Aleph Ono, vintage about 1997 or so, followed closely by an LP12, ca 1998. Speakers and tuner both are from 2000. Newest gear is a cd spinner, Simaudio, ca 2011.
