Yes, the quality of the power cable on an LPS can make a notable difference. When I had the EtherRegen switch, it wasn’t until I put an LPS with a very good power cable that it made it worth it. I would try on the LPS of the streamer first as it is the most delicate of the two. For streamers and their power supplies, you will hear a good amount of improvement if the power cable’s capabilities have advanced shielding and noise reduction properties.
On my 5v LHY LPS for my Node 2. The sound signature of various brands of cords is discernable. I can easily hear the difference between two cords that are the same cord (the no longer available Cable Pro Vitality) but, each of the two has different ends (Iego Gold vs. Oyaide 004). The cord with the 004 ends is clearly better in this case.
Once you adopt the idea that everything matters in your audio system, from the wall receptacle all the way to your speaker footers, then the idea that power cords can be and often are very component and even system dependent needs to be embraced.
A shielded power cable of sufficient gauge for the amperage involved should be suitable. But, if you have extra "audiophile approved" cables laying around then, why not? Better yet, if you have both then try each and listen for differences. Once you have it nailed, have a friend or spouse switch them without your knowledge and let us know what you hear.
I say no based on experience with the Sonore OpticalRendu and the 'audiophile' power supply and audiophile cable they sell for a lot more money (not power cord) I compared this audiophile variant vs 2 other standard OpticalRendu's. I was not able to do a perfect A+B comparison since I did not have 2 identical DACs.
After this experience I am not spending extra on these type of power supply cables.
@mwh777 I also have a BS Node (N130). The LHY LPS improvement was not subtle.
I'm an "everything matters to a point" guy, so skeptical about spending money on LPS PCs - after all the LPS is supposed to provide clean, linear power right?
Having said that, I can test this with a broken in PC that I already own, and I will start with the LHY LPS later today and report back.
@mwh777 Again, keeping an open mind can lead to sonic benefits.
I compared the supplied cable with a well broken in Raven Audio Sonequil PC.
I used Norah Jones Come Away With Me and Chick Corea Trilogy 2 as test material.
The vocals on on Don't Know Why, when she hits those powerful high notes, were much smoother - no doubt this means less distortion.
I listened to 6 other tracks on both albums and overall better clarity.
Best free tweak ever!
Happy I asked the question and thanks all for the feedback.
@macg19 - anything that needs to be plugged into the main supply will benefit from a good power cable
I’ve heard benefits from my $350 mini system to a $70k system
My own "Audio system" is around $20k (MSRP) and it sounds amazing
Here’s my site that explains some of the issues arund cables
For branded products take a look at

@macg19 - from what I can see the Node N130 has a mains 2 pin power socket
You could try one of your existing Zavfino PC’s on the Node N130 by buying a 3pin to 2pin adapter like this one
FYI - the power cables on both my Node 2i and my Simaudio Moon phono stage use solid silver wire for the Live conductor to maximize their details and dynamic performance.

@macg19 - thanks, hope you can make use of the info
If you have some spare time - take a look at
The photography - thankfully, I'm not as passionate about the phtography as I am cables - that might get me thrown out of the house 😉
Why are mens hobbies so damn expensive - needle point next🤣

About the LHY LPS: Yes, SQ improvement was not subtle. The upgrade requires replacing the internal powerboard as well as adding an outboard LPS so there is no need for adapters.
I replaced the cheap PC to the LPS with a good quality PC I had on hand and that helped too which surprised me.
WRT @yoby’s post above - if you construct DC power cables using solid OCC copper or OCC Silver (even better) you should notice an improvement in dynamic performance, compared to the more standard OFC copper wire generally used.
Even though we are talking about a DC cable, the current drawn by a component reflects the demands placed on the component by the audio signal.
DC powered source components draw less power than Amplification, so using solid OCC silver for both +VE and -VE leads is much more affordable and well worth doing.
If I had to build one...
Please note I have not tried this particular approach for DC power cables, but I have made several AC power cables using a similar, but more complicated approach and they provide stunning performance.

As @blisshifi said the streamer seems to benefit the most from an LPS upgrade so do that first.
Also, not every LPS works so well for every application, for example network hardware seems to prefer 'fast' LPS power supplies, not ones with large capacitor banks that instead work well with DAC's and streamers.
