Do you sell the stuff you don't really need or fill up your closets with it?

I do my very best to hand it down. But why there is this bag of generic cables in my closet completely escapes me. 

I have a lot of gear in boxes.  I can't bring myself to sell if for nothing.  Maybe one of my boys will use it someday.

Have a pair of Von Schweikert VR-4s that I think my youngest boy will want when he has space for them. 

I have a lot of cables in a box. 

I did force myself to sell a conrad-johnson preamp and Gustard R26 dac.  Traded in an older Coda amp that needed re-capped towards a new one. 

I still keep my 25 year old Audiolab 8000LX integrated, though I haven't used it for 15 years. I like it, it works fine and it makes little sense to sell it for $300 or so. It's a good inexpensive little British integrated that delivers some music.
