Thanks for posting your virtual system. Very nice. It really helps with recommendations.
If you are installing direct lines I think it makes sense to install audiophile grade outlets.
By the way. A case of beer is too much to install an outlet… one beer appropriate.
I would just do a hospital grade outlet if you are not putting in a direct line. The direct line will have a much bigger impact that just the outlet.
If you do not have direct lines (two preferred, one for amp, one for the rest), I highly recommend doing that.
