Synergistic Devialet Power Cords

[zambie]

Zambie, thanks for prompting me to re-examine this. I did another listening test, with clearer results now that I've upgraded other equipment.

I have a Cerious Technologies "Graphene Extreme High Current Optimized (Blue)" cord which I've used in my power chain, but connected to my Shunyata Research Denali power conditioner not directly to my Devialet amps. When I got it I found it slightly better sounding than a Shunyata Research "Venom HC". That was with a Devialet 400. In the mean time I've upgraded to a Devialet 1000 and Shunyata Research "Alpha HC", so repeated the test. There is a much greater difference now. The Shunyata cord is far better: adding much more "meat to the bones" of the sound. I'd otherwise describe the difference as a bigger soundstage with more bass extension, more separation between instruments, and more tonal texture. For example, in Keith Murphy's "Great Big Sea" he both plucks and thumps his guitar while singing. The percussive thump of the guitar body resonating is more noticeable and separated from the sound of the strings and Keith's voice is more realistic and present through the Alpha HC. The Cerious Technologies blends all those sounds together and makes it sound further away as well as less tangible. The Cerious Technologies is comparatively bright, which emphasizes details. I hear more detail with the Alpha HC, but within a fuller mix of sound so the details don't stick out so much. It is similar to using small monitors (like the KEF LS50) versus full-range speakers (like B&W 802): some high-frequency details are more obvious through the small speakers but only because they lack the ability to convey the full range of sound in the recording. So if one's system were a bit soft and not full-range the Cerious Technologies might be excellent to bring out detail. I do really respect the Cerious Technologies cord for this. If I still had the LS50 I might prefer the Cerious Technologies cord. With my B&W 804d3 I clearly prefer the Alpha HC cord. Again, thanks for prompting me to re-examine the difference with my updated equipment. I hope my thoughts are useful to you.

Arghhhhh  ... just what the doctor ordered - another power chord for me to investigate. Thanks for your really detailed note Deviousalet! 
I'm intrigued about a couple of things: you mentioned that you have the CT GE High Current version - when I contacted Bob from CT, he directed me to the low current option (red). I'll be plugging directly into the power mains @ 15 amp wall. Wondering what triggered you to get the Blue? Also - from what he mentioned, it seemed like both the blue and red were better used without power conditioner (the GE Yellow is the one that was recommended for use with a power conditioner).
That you're stating that the Shunyata chord is far better is definitely going to make me (re)consider power chord options. Curious about the HC variant that you've selected (which I presume is high current). IF you could shed some light on that - would be much appreciated. Is it that the 440/ 1000 are drawing more current? Just to clarify - is it the EF or NR model that you went for?
It seems like in your listening tests - there's a clear difference in the sound you notice - which is amazing given the positive review of CT GE for other amps. Did you ever consider Synergistic Research?
