I'm pretty excited about my new room i'm building

@oleschool

I have one thing you should consider and it was brought to light in at least one post to this thread. Room treatment. Yes, it is important. But, I'd recommend that you just finish the flooring, walls, ceiling, lighting, etc. Then leave it empty besides your gear and listening position, then once you get used to the sound, implement treatment slowly. I have done this over the last several years and all I needed to do was corner bass traps and it sounds excellent. I put a low/medium carpet on the floor and no wall decorations of any type. It sounds amazing. I know each room will sound different, but what you don't want to do is go to far right off and over damp the room. That'll take the snap and sparkle right out of the music and make it sound dead. Also, note that if you choose some type of wood flooring or just seal/finish the concrete floor, it will be very reflective and maybe too lively. I know one person that had to just take the flooring out and go with a low carpet due to this problem. Again, all experiences will be different, but take it slow and do as little treatment that allows you to really enjoy the room. You can also experiment with pillows, blankets, etc on the floor and in the corners or along the walls to get some idea of what carpet and other room treatments will do without having to spend, wait for them to come, and then be disappointed. Best wishes to you and have fun!.

Of course I will employ this method until I find where I need to be . I had a huge improvement in sound and bass in my small room with adding panels. It took the bass from boomy to much tighter and the bright reflections mellowed immensely . I have a home theatre I never post about here , it s in a large space with vaulted ceiling and has huge slap echo .I can incorporate any remains panels and diffusors there it needs quite a but .I will also use large rugs etc to help the situation ,as I stated I am very interested in making it good not great .I cannot fathom not putting my art I have collected on the walls of my man cave audio room .THose days are behind me chasing the ultimate sound ,its hyper addictive and the diminishing returns a 10 fold often . I want a good listening space comfortable for three and maybe a game or two of English darts maybe some pool when not just zoned in .Its a difficult balance ,when I was in my 20s I had a impressive 14x18 arched type roof listening room with two chairs and 2x2 .I have vered away from that world after a lifetime of playing guitar etc. I will certainly play some music in this room too but mostly acoustic or a small tube amp with my electric 

I also want to thank everyone for there responses ,I wish I had an unlimited budget . But I am constantly rebuilding and working on my ranch and am breaking ground on a 3500 sq ft workspace for hotrod and motorcycle  fabrication .

BTW pool table sounds great!!!!!!!!

You always know when it’s a Ducati coming down the road with it’s Conti pipes (nothing else sounds like them) 750 Honda Firestorm with pipes came close.
It’s said Fabio Taglioni (I bow my head) the man who made Ducati and the 90’ inline V-twin, labour for months over what he wanted it to sound like.
A it came to him that very human spent 9 months hearing/feeling his/her mothers heart beat, and that was the firing order he mimicked. It’s in the old coffee table book the History of Ducati

Oleschool, I did look at the acid product your going to use. When it comes out right you can obtain some very cool results. First time I saw it was in a bar and it really looked cool. You want to have variances in the colors to give it that patina look. I chose a rust color and it did not come exactly as I wanted. A lot depends on the porousness and finish of the slab. If memory serves me, length of time with the product on the surface helps in obtaining that patina look I was mentioning. I also think muriatic acid can be used within the application? I also used a stiff brush to work the product in attempt to get that off set in color. It has to be sealed after completing. That really brings the floor to life. Because its not a commercial building a good sealer should last you a while. I used a water based sealer, I'm sure they must have oil base as well? With Cali. that's likely an issue?
Several epoxy products out there. Its a 2 part application, and don't know if its a first time DIY project? Once its down it's easy to maintain. I've seen it dusted with flakes to give it texture and a certain look. However its a solid not transparent look.
I'm jealous of your of the grid power approach. I'm on 40 acres surrounded by 300. I use a water stove. Essentially a boiler, with pipes underground that pump through a heat exchanger. Its about 100' from the house. Heats the house and hot water. I use it year round. Lots of cutting and splitting  of wood. Emerald ash borer are killing all the ash trees so that's what I've been harvesting here in NC. It migrated down from Canada. If I were to do it again I would take your approach. I have a stream behind the house and I get sun all day. Too far along in the game now for me, but I tip my hat to you with your off the grid living! I Couldn't imagine living any other way. Good luck...
