Does Storage Damage Equipmnt?

If current system photo is the state of your system's room, then please consider some dampening behind/beside speakers, Speaker toe-in, and floor covering. In other words refection treatment(s).  Not expensive relative to other bits. Mr. Gorbachev take down that plywood.

If door doesn't swing into room moving L speaker move more to left should help too.

Mr. Gorbachev take down that plywood.

behind it is a wide open closet . REL support recommended the closet opening be closed . 

It looks like you haven't quite settled in to your new place yet. Walk around the audio room while clapping your hands. If you hear and echo from the hand claps, as I suspect you will, your room is too lively as is and will need some dampening and/or room treatments. Start with simply covering the floor and windows with carpets and drapes and go from there. Good luck!

Damage?  Not likely.  Well, excess humidity, and heat can damage something but not in a subtle way.  Usually this evidences by loss of functions, cracking or popping sounds or total loss of bass or treble, scratchy volume controls, etc. 

Otherwise, the room, power and Class D amps may be the culprits.  Nothing wrong with Class D, but some take 3-4 days to warm up after being powered off for any length of time.  

In your case I suspect the issue is more ot do with rotating the system around without significant room treatment on the side walls.
