Unless you are in need of cash, I would put the gear in storage just to make sure going purely streaming is your final solution. I own every piece of gear (including the boxes and manuals) all the way back to my first system in 1977. I have 5 different listening rooms with various states of Vintage Gear or themes, and the rest is in storage or rotates in the rooms. I'm glad I've never parted with any gear.
My wife...not so happy.
