MCRU Linear Power Supply for X12

There is a review  on the Cocktail Audio UK site, that I remember commenting on.

I have not tried the MCRU power supply, however I have tried the ifi-audio DC iPurifier (newer version is the DC iPurifier2) on a Cocktail Audio X10 with very good results. All of the things that you would expect, better soundstage, dynamics, clearer trebble, punchier bass, better timing, less background hash, and just a more musical presentation. This was with my X10 connected via optical out to a Naim Superuniti / KEF LS50's.

So while the better DAC/AMP in the Superuniti will have highlighted the sound quality improvements, this was before any possible improvement to the sound quality of the X10's internal DAC/AMP. Which is something that I could not test, as I never did use the X10 as a stand alone device.

The DC ipurifier sits in line between the PSU output barrel plug and the device barrel input socket and uses active noise cancellation, to cancel out the noise from switch mode power supplies. It is compatible with 5-24 volt DC power supply units (up to 3.5A, 84W) and comes with adapters for different barrel plug/socket combinations.

I could not say how it might compare to a dedicated linear PSU in terms of absolute sound quality, but it is a good bit cheaper than the MCRU PSU and a great deal more versatile too. So if you have considered upgrading your power supply but do not want to spend too much cash, or be stuck with a dedicated PSU when you upgrade your equipment, perhaps this could be of interest to you.

I originally bought mine to use on a Monitor Audio Airstream S150 bluetooth speaker (which I believe had a 17v DC input so little chance of getting a linear PSU at that odd voltage). It brought the same sound quality improvements to that as well.
