End of the World system

Just as I am today, I'd be very concerned about durability. I want good sound, but I assume that I'll get used to whatever I have and waver between loving the sound and hearing nothing but problems. The end of the world would only make that part of it both worse and better. I just don't want any of it to break!
 
Inside:
preamp - McIntosh C52
amp - McIntosh MC611 (x2, or maybe just a 2-channel MC462)
turntable - Technics SL-1200G (and a whole crate full of cartriges)
CD player/transport - Yamaha CD-S2100 (or something from Marantz or Denon. I'm operating on the premise that these mass produced models are probably more reliable than something high-end and esoteric)
speakers - JBL K2 S9900

Outside:
preamp - SPL Director Mk2
amp - Crown XLi 3500
turntable - not outside
CD player/transport - Yamaha CD-S2100 (same as inside, probably even identical in case they need to be put together for parts)
speakers - Klipschorns in front of a really long wall

I know, I put the Khorns with the Crown and the JBL K2 inside. I had to give you all SOMETHING to complain about!

With the new guidelines:

preamp/dac: Mytek Brooklyn DAC+
amp: Mytek Brooklyn Amp+
turntable - Technics SL-1200G (if I had room for records, and I'd still stuff my pockets with cartridges every time I trekked back to the store)
CD player/transport - Yamaha CD-S2100 (just something reliable)
speakers - TAD Compact Evolution 1

Good speakers are going to be heavy no matter what - even these stand mount models. It's a labor of love though. The Sonus Faber Electa Amator III is also fantastic for a small speaker. I'm not wild about Sonus Faber in general, but if you gotta save space, those are pretty special. Harbeth HL5 perhaps?

Or one could go with a Nagra Classic series setup. Oooh, I don't think I could leave that in the store overnight.

My reality would probably be closer to yanking speakers out of abandoned cars and mounting them in Rubbermaid storage bins, but if we're dreaming here, Nagra and HEDD Type 20 maybe.

It's not really an answer to this exercise, but in my post-apocalyptic world, I probably build my whole cabin out of speakers and build the walls of other audio gear. So that's kind of the most efficient use of materials, and I get lots of choices when I want to check out various combinations. In fact, I heat the place with tube amps. LOL
