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?

My audio system has two sets of amplification. When I want to really sit back with a fine single malt and get involved in the music, I turn on my tube mono blocks using CDs as my source. When I just want to have background music on or tunes for a party, I switch over to my SS amp. This saves life on the tubes and gives me a backup in case I need service on my main system. Both systems use a tube based preamp and the same set of speakers so its not exactly like having two separate systems but it serves my purpose well.

I'm keeping enough separate components on hand so when my daughter gets set in any one place long enough she will have a system set up.  I gave her a McIntosh RS100 for their current apartment, which sounds great (if they would just play it loud enough).  When they get settled someplace, I'll give them a real system to play their "indie folk".
If you can afford it, hang onto your "emergency" gear.  If your car needs tires, brakes a new fuel pump, and a tune up, then sell it and take care of more pressing things with that money.  Let's face it, getting to work is the absolute most important thing in life, that is while one is still working.   
If you run tube gear, as i do, it is quite nice to have a backup ss amp around for a couple of reasons, 1) The ss sound is a different 'flavor' to the tube sound and 2) if the tube amp needs service, the ss amp is there.
I keep a PS Audio Stellar Gain Cell DAC and NAD M22v2 amp as backup to my main system.  Over the last year, I've used them at different times when I sent in my BHK pre amp and BHK 250 amp for service.  

The M22v2 sounds pretty good in my main system; the Stellar DAC sounds OK but the SQ is no where near the BHK pre amp.  At some point, I plan to buy a decent pair of speakers to pair with them.
