Do you have any gear that was outright given to you?

When we bought our house, the previous owners left a complete midlevel stereo including two TVs. They did not ask for any money, did not expect it. Gave the TVs away, of course [we are a rare no-TV household], and most of the other stuff as well over time, as I upgraded various components.

I still use a CD player, two Furman power conditioners, some cables, some of the in-wall speakers, and one sub.

Some large Advents before going away for college.

I do not, but I have given away a Classe Audio DR5 pre, a pair of Classe Audio DR8 power amps, a Marantz SACD player, and a pair of DCM Time Windows.  All to my friend, and he was quite happy.
