Power cord upgrade for ATC 100A Active Speakers


Hello:

I've just acquired a pair of ATC SCM100A active speakers, and I'm wondering what other users of ATC actives have done regarding stock PCs versus upgraded PCs.

I did a quick test of a cheap PC versus a Cardas Clear Beyond Power cable, and was surprised to NOT hear a big difference, given that the same cable made a huge difference in my previous (passive) system (a Benchmark AHB2 and SCM 40s).

In that setup, the Beyond PC increased the mid/lower bass, and provided more slam and musicality.  It felt like a component-level upgrade.  I expected a similar improvement with the 100As...not that they sounded lean in any way with the stock PC.

Would love to hear from other ATC active owners who upgraded their PCs.  What did you choose?  Did you find a big difference, or was it just a box-checker?

Thanks in advance for your advice/experience in this matter.

Best, JAMES

Yes , I get it. For me that’s my current bottleneck. I’m not running high power SS gear so I’m not suffering too much. FWIT , I installed a pair of the better Hubble medical outlets on my existing 15 amp circuit. They happen to be 20 amp outlets but that doesn’t matter as I’m aware not to overload the circuit. I have a new service panel and copper wiring. I run a Richard Gray power filter that has a super beefy factory cord. Due to having the 20 amp outlets I purchased a Shunyata Venom HP 20 amp cord to try. I have Morrow level 4 and Analysis Plus cords to my gear. When I switched to the Shunyata cord that essentially feeds everything else the change was very noticeable. I apologize for being a snippy old B , but I have found that wire CAN make a difference for me in my system. And being an old dinosaur I came from the camp that wire is wire and spiked speakers are the best. You can teach an old dog new tricks but he still occasionally pees on the floor. Chers and Happy Hunting. 

I am not running ATC speakers, I am running GE Triton Reference speakers with powered woofers. I wasn’t pleased with the cheap power cords that came with the speakers, so I am using a pair of Pangea AC9 power cords on them.  I had them hanging around, unused so I thought why not. There really wasn’t any difference between them and the cheap power cords but I have left them in for the past 8+ years.  I have the power cords connected to a Shunyata Hydra and connected to a 20 amp dedicated outlet with a. 10 gauge Shunyata Copperhead cord. Had I not had all of this hanging around, I would be still using the original power cords.  

Perhaps fruit for thought:

Several A-Goners have remarked that upgrading power chords provided the most dramatic SQ improvements with their AMPS & PREAMPS, and the least improvement with TT and speakers...

Always demo...

Cheers,

@jimboman I would recommend you try nordost cables. Heimdall 2 and Frey 2. Used they’re not terribly expensive (depending on your budget). I don’t see how or why they wouldn’t improve the sound or at least make a difference. I’ve used these cords on every component from streamers to amps. If their sound signature (airy, fast, relaxed) is to your liking you should hear these qualities in your system when these cords are feeding the speaker amps. 

@audphile1  Thanks as always for the great suggestions.  The Frey 2 is probably more than I want to spend - ain't that always the way - but I'll keep my eyes open on the used market.

I am also a fan of the Cardas PCs, and have a hankering for a matched set of Clear, if the right ones come along.

Thanks also @inagroove and @stereo5 for the food for thought.  I'm definitely going to upgrade the stock PCs, once the right options become available.

Best, JAMES.
