Synergistic UEF Blue v. Cerious Graphene Matrix Power v. Mad Scientist Audio Nitro Nano

Hi everyone,

I am debating between 3 power cables for use on my Pass XA30.8: Synergistic Research UEF Blue High Current, Cerious Technologies Graphene Matrix, and Mad Scientist Audio Nitro Nano. I am primarily seeking increased transient speed, detail resolution, and bass slam. I like the effects of graphene in my system: I use Cerious Graphene Extreme speaker cables, a Synergistic UEF blue fuse in the XA30.8, and Mad Scientist Audio graphene contact enhancer on connections/Black Discus Nano on power cords, all producing apparent improvements.

The rest of my system: Bluesound Node 2 streamer > Schiit Gungnir Multibit DAC > Krell KRC-3 preamp > Pass XA30.8 power amp > Klipsch Epic CF3 (rebuilt). Current power cables are Audience Powerchord-e. Interconnects are Audioquest Colorado Xlr w/72v DBS.

Which power cord do you think would be best? If you have experience with any of these options, I’d love to hear your thoughts/experiences.



Seeking a PC that can best the Powerchord-e under 1k, preferably less.

I picked up my Purist for just under $1K used.
Triode Wire Labs silver obsession is a giant killer.
very detailed, huge deep soundstage not to bright and not to smooth- just natural and organic.

My best MC to date has been the Sablon Elite.

I have Gutwire on test atm, they are good but mucho expensive and unwieldy.

Davids suggestion of TWL sounds good as well especially considering the price.
And don’t forget about the plugs, type and make. Furutech NCF, leGO are good, Bocchino are supposed to be the ultimate but haven’t tried yet.

Also don’t rule out off the reel cables like Nanotec 309 etc.
