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.


I don't own Pass but from what I've read, isn't the consensus that after market power cords don't do much for the sound? Hasn't Mr. Pass commented his amp designs and "build" don't need an aftermarket cord? Pass owners will chime in I'm sure, I'd like to be enlightened.

there's also some interesting reading out there about Pass Labs and Silent Source power cords and cables...
Hi OP, 

Your system sounds excellent. I want to push back to say that the next bang-for-the-buck purchase for your system may not be power cables for your downstream gear. Consider placing a reclocker between your streamer and DAC. Upgrade the PC into the Node if you haven't already. And if you're running ethernet into the streamer, consider placing power supplies on your modem and router, if you haven't done so already. For streaming, I've found that the modem and router are part of the chain. 

I used the iFi power components because they were most affordable. In my experience, I added those LPS's over time, and can say that the sound went from raw to refined when I replaced the streamer PSU. The modem was slight, but it added resolution and body. Then the router PSU changed the sound from edgy/fatiguing to relaxed. Best
The CT Matrix cables have enabled me to stop my long time search for the best cables.
Thanks everyone for your replies. I am leaning towards the CT Matrix. I really enjoy my GE speaker cables and am looking forward to hearing what the higher Matrix line would bring.
