Any point in upgrading stock cables for a LPS?

My thought is no. But I may end up with an extra good quality PC so curious where it may be put to good use, if at all.

I have a 5v LHY LPS for my streamer and a Goldnote PSU-10 for my PS-10.


Yes, not only the AC but also the DC cord can give a marked improvement in sound quality. Vibration control on power supplies also yeilds nice results.

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.

  • from the perspective of current draw, the current actually has a :"ripple" type of waveform that reflects the audio signal, but it’s definately not alternating
  • if the cable cannot satisfy the demand, then the voltage also experiences minute drops at the same frequency as the audio signal
  • so it can have certain "properties" to AC power.

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...

  • I would use 2 x 20 or even 2 x 22 gauge for each conductor and tightly twist (i.e. 6-8 twists per inch) them together - that’s effectively 17 gauge.
    • one pair in a clockwise direction and
    • the other pair in an anti-clockwise direction
  • insert each twisted pair wire into a Teflon tube and seal the ends with heat shrink (this prevents oxidation)
  • twist the two conductors together in a relaxed twist
    • i.e. one twist every 3" - 4"
  • insert into expandable nylon tube for aesthetics
  • attach the required connectors

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.
