Looking to Upgrade Outlet

I just had a dedicated line installed for my system and I'm looking to upgrade my outlet and need some recommendations. My current outlet is hospital grade and I'm hoping for recommendations based on my current system and sound preferences. I read many threads here but too often there are so many suggestions that it becomes too confusing just like cables and tubes.

My system consists of the Primaluna Dialogue Premium integrated amp with 6 Cifte 12AU7 and 4 GL KT77 tubes driving Lawrence Audio Violin SE speakers and a JL Audio E110 sub and my sources are all digital. My digital, power cords, speaker and RCA cables are all from Synergistic along with their FEQ, XOT and ground block. The power cords are connected to the Core Power Tech 1800 and all fuses have been upgraded. All connections have been treated with Total Contact with the exception of the power line into the outlet.  I don't plan to make any equipment changes now that I'm retired. My system is very musical and don't like anything that's analytical or bright sounding. 

Please, I don't want this thread to be another controversial subject about snake oil, etc and please no negative comments.
