Qutest with the MCRU power supply

[Hondoe1950]

I just installed the MCRU power supply on my system for the Qutest DAC. I had read a lot of different opinions about whether it made much difference or not. I’m sure it’s partially system specific. But on my system: Cambridge Audio Edge A amp, WiiM Ultra streamer, Rel sub, and Revel M126Be speakers, it made a really really obvious and powerful difference. After reading all the mixed reviews, I wasn’t expecting much and the change was not subtle at all. So if any of you are considering this combination, I heartily recommend it.

By the way, switching the Qutest from one volt to 2 Volt output on another day also made a giant difference.

I have the feeling someone will be along shortly to ask whether you've blind tested these combinations.

It'll certainly be louder....

This Is a feature I love especially if you have very sensitive speakers and/or an amp with an energetic gain

But in regards to sound voltage change doesn’t make a jot of difference its just louder

I know some run it of a battery pack and say it makes a difference, though haven't tried myself

He said the change wasn't subtle, so he's guaranteed to be able to identify, blindly, how it's being powered 🤔

Can I ask you to switch back to the standard power supply and listen again? Also get someone to do a blind test with you. This subjective comparison nonsense is beyond a joke nowadays.

It's sensible to think a better, isolate power transformer could make a difference in theory.

To me it makes sense to spend £200 on a £1,300 DAC to try & get the best from it. Assuming you didn't also 'upgrade' & add another £200 for kettle lead. That's where I'd draw a line. I hope the op enjoys it, regardless. That's the game.

My skepticism might also just be fear that I'm missing out on awesomeness by not spending £3k on kettle leads, xlrs, an ethernet filter & cat8 cables...

It's not sensible to assume anything. In the case of power supplies you can measure distortion at the DAC outputs and find theres no difference so why would it sound different? Rob Watts says theres no need for aftermarket power supplies.

I seem to recall that an early test in Hifi News also tried a different power supply. I’m less persuaded that it changes the sound coming from the DAC than the possibility that it injects less crap/noise into adjacent components.

That is quite possibly where the improvements lie, which is also why somebody else won’t benefit! Hence, it’s very system specific, rather than an automatic improvement to the Chord.
