Synergistic Research Atmosphere Power Cords.


For those who have been following the SR Red and Black fuse thread in the Amp & Preamp forum, it goes without saying that I loved the way they transitioned my audio system. What I thought was a highly resolving system has been transformed into a system that has been improved in every way ... drastically.  For many of us, me included, our music collection and the playback system is a labor of love. I've been working on mine for over 40 years now.  

 

After I got into the SR fuses, I started watching SR's youtube video demos. In watching the videos and reading  their literature, I discovered that their new power cords used the same technology as their fuses. That got me to thinking ... if a one and a quarter inch fuse could make such an improvement in the system, what could a five-foot power cord do? I decided to find out.

 

Four of the new Synergistic Atmosphere Series level 3 AC cords arrived at the house.

When they arrived, I unpacked them right away and was totally impressed with the build quality and materials used. More beautiful than the pictures depict. A shame no one is going to see them because they are behind my equipment rack out of sight. But it sure is an indication of the builder/designer's pride of workmanship.  My first thought was ... Wow, if they sound half as good as they look, they should be great. With most things in this hobby, I've acquired a wait and see attitude.

 

I removed my old PCs and installed the SR's right away (of course). They were replacing two different brands of custom PCs.  I had found through the years that this combination of PCs to beat anything else I tried, especially in terms of musicality and digging down into the organic sound of real instruments.  Two were built by the Music Advancement Company (MAC) in Oregon. The other two were custom built by David Magnan, a very respectable cable builder and a fine gentleman. Those who know Dave's cables know what I mean. Throughout the years, I've had the privilege of using most of Magnan's work from his speaker cables, ICs and PC's. They are exceptional. So, this gives you an idea of what I'm comparing these new SR cables to.

 

After installation, I warmed the system up, adjusted the bias on the amp and sat down for an initial evaluation.  What I heard right off the bat was an overall improvement in the areas we really like ... bigger , wider, deeper soundstage. More transparency. Far less grain .. in what I thought was a grain-less system. I thought the SR fuses had finally bought me to a grain free audio Utopia. Ha ... silly me. That's the good part.

 

Now, for the rub: The SR PC's, right out of the box, were doing exactly what the SR Black fuses did and that was to introduce a hard edge, especially on strings. There was an overall degradation in musicality and emotional connection to the music as a result. The reason? The PCs , like the fuses, need at least 100 hours of break-in before they really come to life. Like the fuses, I could hear the promise of these PCs right off, but man, new out of the box, again like the fuses, things  just weren't "right."  It reminded me of when I first fired up the new ARC REF-75se. It took 500 hours for the caps in that amp to finally come around full tilt.

 

So, as these new SR PCs break in, I'm going to chronicle the experience in this thread all the way from new to tatal break-in. From what I've heard so far, they offer great promise, trouncing my old PCs in so many ways. Now let's see what they can do musically as they break in.

 

Stay tuned ...

Ralph,

I'm curious what technically constitutes a power cord that "works very well" with your amps and what are the ones that work best at various price points?

Thanks.

Specifications with specific product examples that meet those would be great but I'll take anything objective to know one when I see one.

What sounds like live music in a home environment is a totally subjective conclusion.    Plenty of those to go around.


Op yes I have been to Classic Audio Reproductions with Atmasphere amps room at Capital Audiofest and the sound was top notch although the small cramped  room was a limitation most likely. 
Yes I seem to recall that discussion and does make senseat least for power amps.   Thanks for the repost Al. 

For line level devices I suspect shielding is the most important factor.  

Pangea power cords seem designed with these two things in mind accordingly.   I use their line level power cords and noticed an improvement over stock cords.    I'd like to try something like theirs for my power amps someday.  

I’m interested in Atmasphere’s view specifically about what constitutes a power cord that works "very well" with his amps and some examples at various price points if possible.

Any good quality power cord should "work well" I would think but if Ralph knows from his extensive  experience some work better than others for known reasons I’d like to know.

Lots of people approve of many things which is fine. Its not about that.

Would also seem to make sense that the wring in most homes must be well suited in this regard otherwise that would have to be the bottleneck and that mass produced wiring can't cost much in comparison to many audiophile products. 

So I gotta  wonder how hard and expensive meeting that criteria in fact really is.  
Yes I agree the warm to the touch observation was a very useful one for clearly determining if things might be working better than they are.

Also the comment about how simple commercial grade in house wiring seems to be up to the task as described is an interesting one to take note of before dropping a bundle on power cords perhaps..
