For those of you that want to tweak and improve without voiding warranty using a different PSU for your M Scaler:
I know I have issues with RFI (ground loops too?) in my system and have been looking for ways to improve sound
not spending too much and also not voiding warranty.
I ordered this power cable from Clearer Audio,
https://www.cleareraudio.com/products/copper-line-alpha-power-cable.
It seems to be a very well made cable and according to spec it's high quality copper, good shielding
and you can order it with 2 "super suppressors" (ferrites) and good Furutech connectors for ~£130.
It's also possible to order shorter lengths which I did (0.6m).
I use it with the stock PSU and I think the improvement equals that of the PSU upgrades I've done previously.
Some of the harshness is gone and there is definitely added depth.
I also think my result aligns well with Rob's comments on the subject recently where he said that it
doesn't matter where in the chain you mitigate RFI. It doesn't have to be in the BNC cables.
That comment was for ground loops though I think which I'm not sure I have since M Scaler only has a 2 prong connector, i.e. no ground.
This cable and a battery pack (Sandstrom 20000mah) for the Qutest has really made my system sound the best I have ever heard so far.
Or rather, they have allowed Qutest and M Scaler to do what they do even better
