Keeping backup equipment?


I recently had to send my amplifier in For service. In its place I picked up a used Schiit Vidar to tide me over. 
So now that I have my main amplifier back and it seems to back to making me happy I’m wondering if I should keep the Schiit or sell it. On one hand it makes sense to have a backup ready to go, on the other my main amp has
been flawless for several years. So it sort of seems a waste and maybe someone, like me, may need one on the cheap.

so for those running separates, do you have backups stored away for emergency’s?

I only keep speakers and source equipment that I find exceptional compared to what is available today. Some components just seem to find a special place in my mind and aural memory. IF, I SOLD, I know that I would regret it sooner or later. If I needed the money to pursue an upgrade that would be a tough decision and I am sure it would require some serious internal debate. Newer is not always better, then again,  we only live so long and we must balance the curiosity of owning something different and perhaps letting others enjoy our past favorites. 😉
Only one system. It’s in the living room as I am happily single.  No need for cramming it all away in a room due to aesthetics, I run the place as I see fit.

so with that said it seems wasteful to keep a perfectly functioning amplifier socked away. But then it was handy to know I will have tunes and my daughter can keep on her cognitive therapies from Home if this one goes down. For what I paid (used) that.m money could be out to use elsewhere.

I think I usually tried to keep a small number of backup components which could work their way into an office system... a break in system. It’s a question of balance. But using for trade in is a great way of giving your dealer a way of discounting the piece you want to buy. This way he can show the manufacturer that he changed you full price, but give you a great deal by paying you too much for the trade in.
