The new Audiolab Q-Dac is a more competitievly priced alternative to the M-DAC which benefitted enormously by using a better power supply. MCRU have sold 100’s of linear power supply’s for the M-DAC with every customer reporting the same, massive sonic improvements. The Q-Dac has the same power supply requirements and will also benefit from a better power supply, here it is!


Please note this power supply can be supplied in 120V or 240V to suit any country in the world and will be supplied as standard with the correct mains lead to suit your country, such as UK plug, Schuko plug, Australian or New Zealand plug and USA plug. 

MCRU and Londog Audio have developed an external split rail fully regulated linear power supply to take the Q-DAC to the next level.

The power supply is designed and built in the UK by respected engineer and audiophile Nick Gorham who owns Londog Audio. Nick designs all the MCRU power supplies, many of which have been awarded recommended badges in the hifi press.

Styled to match the silver or black qdac casing, the power supply is supplied with a standard mains power lead to suit any country, UK, Europe, USA or Australian versions as well as 120V or 240V. We ship worldwide and many of our power supply’s are already in use globally.

Here is the first review from a satisfied customer who uses the M-DAC:-

I plugged this in yesterday, after twenty seconds I came to the conclusion it’s never going back!

Build quality is good. Nice solid case, four rubber feet. The main thing that used to concern me badly with the M-dac was the power connector, from the unit to the dac itself, flismy and unconvincing fit. I was never happy about it (could ruin the whole thing and I worried you can break it by looking at it too hard). This has been remedied by a much chunkier plug that fits convincingly now:Excuse the horrible quality photo, M-dac owners however will appreciate how much better this thing looks. It’s a firm and convincing fit, a big weight off of my mind.

You might have read that I got some new isolation platforms not so long ago, they gave me a soundstage like I’ve never heard before. Adding this to the chain immediately improved this substantially!
All of a sudden my M-dac has control over the entire sound spectrum like never before.
Bass is deeper, but not overblown (drum and bass never sounded so damn good). It hits with such slam now! I didn’t realise I was missing this until I heard the Lampizator a few days before, it hurt, losing that again… I feel happy to have it back and know it’s going nowhere
Vocals and mids are to die for, they’ve always been something I’ve loved about my system, I worry that it can be taken too far, in this case, clarity has improved without sounding clinical, everything is so musical!
The top end is clean. Some music I have has analogue flaws added to the sound. Hisses crackles and pops sound so natural and organic. Cymbals decay properly, with the most delicate shimmer I didn’t know my system could deliver.
I’ve not got a bad thing to say about this upgrade, every aspect of the sound has improved dramatically. I’ve bought a bespoke granite platform for it and some RDC cones to ensure it’s properly isolated. David provided a no.27 cable to test it with. Great build quality, that’s not going back either.


Excellent upgrade to my M-DAC, all the usual Hi-Fi sonic attributes eg bigger soundstage, improved detail etc. But the most important thing is that I haven’t stopped playing music since the PSU arrived:) Highly recommended – thank you David.
