Out building for sound. The dream ver$e$ reality

These are my developing thoughts on what to do. I would appreciate comments from those that have been there or in the know. Or know "The In Sound From Way Out!"  

I’m in the planning stages for an out budding used for a bit of photo work but mostly for listing to music.

I may have champaign tastes but my budget is more draft beer like.

I most likely will go w/ a set amp and big Klipsch’s or Tanny’s. Source will be steaming only. One the other hand the all in one darTZeel lhc-208 might be just the thing as I can’t afford big mono’s, pre et all. (I have to get the building up.)

It will have a dedicated 20AMP line run of 10 gauge solid core into audio grade plugs.

Floor will be wood.

Getting in internet via a 175 foot fiber run is my hope.

Wall studs will be staggered and walls filled w/ sprayed foam.

If need be I’ll be adding Sonitus panels or the like.

Dimensions will be 12.5’ high by 20’ wide and 29.44’ feet long.
