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.

I appreciate everyone's responses and suggestions. I understand that any component is system dependent and based on personal tastes. I also understand some are skeptical concerning outlets, but I found that changing power cords and fuses had a dramatic impact to my system. Additionally buying a companies higher priced cables doesn't necessarily mean it sounds better. As I stated, it's a matter of tastes.

I'm leaning towards the SR black since I use and I'm happy with SR cables and tweaks as folkfreak suggested and the fact that SR has a 30 day return policy as David suggested. The 30 day return policy has worked for me several times previously. If I'm not satisfied with the blacks I may consider the Furutech Gold since I found it 33% off list at the cable company.  Since I'll order the outlet thru the cable company, I'll ask their opinion between both outlets.

Thanks again for everyone's input and I'll post my findings. Ron

I have the NCF and the GTX Gold installed in my power conditioner. I find the Gold receptacle to be a little warmer, not a night and day difference in my situation. I will say that when you upgrade to a higher quality receptacle you will get more detail, so be conscious of that. I have heard from people that this is a warm sounding receptacle>> https://www.vhaudio.com/oyaide-swo-gx.html

I would also consult with Chris from VH audio and get his opinion for the comparison between the GTX Gold and the SWO-GX. I would also consider buying from him as well.

To me the NCF is the best I have heard. I would not really call it analytical, but if you have the wrong ingredients as you know, it can expose things in your system, that might make it sound analytical. My system does not have tubes and I am using 3 NCF's and I do not have brightness at all. As a matter of fact, the first thing people say when they hear my system, is how warm it sounds. So I would say to play it safe, get a gold plated receptacle.

Best,

Tom,

You know my tastes best since we swapped tubes and communicate often. I checked the VH website and noticed they also carry SR so I'll give a call tomorrow.
