Power Cables

jfrmusic

Thank you for the quick synopsis, I'll keep the Frankencable in mind

I plan to upgrade my XLR Balanced interconnects to the Ice Age version. I would like to try their speaker cable if they can offer locking banana plugs.

@zlone for clarity, is your statement below related to the direct effect of power cables on the digital and analog gear they are attached to, or the effects of power cables attached to digital gear affecting the performance of other gear in the same rack?

”But at least we agreed earlier that a power cord can make a difference where analog is involved, so they can make a difference. However for pure digital, without any idea how a power cord could affect it, but know they can have an affect on other components, I think we have to look at empirical evidence.”

My suggestion is that regardless of any impact after market power cables have or don’t have directly on a server/streamer, such devices are commonly (usually?) used in proximity and connected to other devices in your system and connected to the same power source, all of which could be affected by the digital device or the properties of the directly attached power cable.  The idea being the better that low level digital and analog signals and high level power cables isolate from each other, the better. Therefore, cables have both a device specific and system level function that are difficult to tease apparent in practice because it requires listening to everything hooked up and playing together in your rack and room and with your power source from the wall. Whether or not you hear a noticeable difference is the important test for whether the cost and hassle of optimizing power or any other cable is worth it.

FWIW on a related note, I modified my Bluesound Node by replacing the internal switching power supply with an external supply from Teddy Pardo and I am as certain as I can be that this improved the sound of digital playback from an attached SSD in my system. Can’t explain whether this is a component or system related effect. YMMV.

@knownothing Good point. When I stated that we don't know how they could affect a purely digital component I was conceding I have yet to hear, in the case of a streamer, how they might affect the sound. Especially in the case where a USB connection is used to the DAC and the clocking is handled by the DAC. I did not address the more general case of properly shielded cords not affecting the components around them. I agree that this could be a primary improvement with an aftermarket cord vs the stock cord.

I am currently selling off some old cables and came across an inexpensive, unshielded 10 AWG power cable I bought last year on a whim. I swapped it in on my power amp, which was using an Acoustic Zen El Nino. After a day I remembered why I pulled it out, a very fine grain was added to all the sound, fatigue in a previously fatigue-less system. Does it need break in, maybe, but I won't sit through that to find out.

FWIW, I am a believer that it all matters and it is very likely that a good cord does affect the performance of a dedicated streamer. Motivated by this conversation, I moved a Wireworld Silver Electra 7 cable from my preamp to my streamer, which is where the seller recommended I put it in the first place, and moved the Acoustic Zen El Nino from the streamer to the preamp. The sound changed for sure, and for the better, which cord where made the difference?

Did I answer your question?

@zlone yes you did - thanks.  And glad you were able to improve your sound by making adjustments.
