I had a Sonos Connect 'modded' by them a while ago. Lets just say the words barge pole would be in my advice.

I thought about changing out the power cord on my PSU1, and want your opinions.
I'm wanting to swap it out with an "Audioquest NRG-1.5 (2-Pole)" , or one of the upcoming models NRG-Y2 or NRG-Z2 (3-Poles) "specs on newer models"
Do you think I would gain anything from swapping the power cord out with one of these?
Thanks Gary.

Thanks Gary.


Before you embark on a power cable journey, have you tried the existing cable by unplugging it at the PSU1 end, and rotating the end through 180° and reinserting it?
Try it if you haven't ....

Report back ....

Big transformer; big reservoir capacitor(s) of the right kind. 78XX voltage regulator with 10uF directly across its output. With ground return taken to the right place. Must comply with Kirchhoff's loop rule. One day I will make one. Direct sale only because in some countries local dealers insist on approvals and I'm not willing to be judged by 'the lesser educated' and charged £20K ($30K) at today's prices, just to sell 63 pieces...

Definitely try what Chris has suggested. Where the mains power cord enters the PSU1, switch the polarity after listening to music for a few hours. Do it as quickly as you can when you do it. Click the wall switch off, quickly unplug, turn 180 degrees, plug back in, wall switch back on ASAP. Then resume listening for a while. You may notice a difference in clarity, stereo image position and bass positioning/presence, a bit like going to the opticians for a sight test and the optometrist asking you if the letters on the lit screen appear clearer with lens A or lens B and you being able to discern a slight difference. The kind of slight difference that makes a significant difference over extended listening. You may not hear a difference, which is certainly what logic tells you, seeing as this is alternating current. My only suggestion is that it could be explained by subtle directionality bias in copper conductors due to high voltage flash testing during manufacture but I honestly don't know.
