Nordost Valhalla Power Cords

Exactly what I said......using some Nordost can make some good improvements. But all Nordost always gives flaw's. It is as easy and predictive as it is!

What about the wall receptacle and, much lesser talked about, the standard circuit breaker upgrades?

As for the former, having spent at least a couple grands alone on the cords (in case of Valhalla PCs), would it be logical to match the (quality of) Valhalla's Wattgate 330i/350i connectors with (the same quality) Wattgate 381 receptacle(s) in the wall? Or at least Hubbell IG8300 (cryogenically treated). What are your experiences?

As for the latter, I would appreciate recommendations for a (cry'od) circuit breaker that fits into a 200A GE panel.

While not the Valhalla model, any thoughts on the Blue Heaven cables/cords?

Well hello John....nice to hear from you. I had three of the Valhalla's Power Cords in my system on my Esoteric set up including the clock. The rest of the system is Purist Audio 20th Anniversary and Canours cables, which if you remember I have always enjoyed and liked the sound of the Purist Cables. I wanted a little more speed and the Nordost Valhalla's seemed to be the right move. It opened the system right up and was very reveiling. Like with all changes yuo make, initially I enjoyed then after a few months that hmmmmm came in. It became apparent that I had lost some rythm along with bass. Don't get me wrong - these are a great cable if the rest of your system has enough base for the room for your likeing and is on the '' slower side '' of sound. I also missed the texture that Purist has so I went back to Purist after about a year. My whole system is once again all Purist - and yes, something can be said about a whole sytem being wired with the same cabeling. As we anything in this hobby ....it's what you like and what works in your system

Blue Heaven are a lot different in sound. Less natural and less drive. Wattgate is quite poor compared to Oyaide. Valhalla uses in Europe a very cheep Shuko of 35 euro. I used Oyaide F1 on my Valhalla. Superior compared to the budget connectors Nordost uses on the Valhalla.
