Merason pow1 Linear Power Supply for frérot, Black

The Merason pow1 is an external linear power supply developed specifically for the Merason frérot, and it noticeably lifts its sound.

It replaces the included plug-in adapter and gives the little converter exactly what it deliberately lacks: plenty of clean, quiet power. Swiss Made, and stackable with the frérot.

Why the pow1?

Three separate linear power supplies with a large, quiet transformer replace the simple plug-in adapter: two feed the audio section, the third the digital and logic section. The frérot is deliberately built to sound better with better power — that's exactly where the pow1 comes in. Reviewers such as Part-Time Audiophile honoured the frérot + pow1 duo with the "Reviewer's Choice Award."

What you hear

More calm in the background, out of which fine details only now properly emerge. Transients arrive crisper, decay becomes more natural, imaging more tangible. Sounds like voodoo, a power supply for over 800 francs? It isn't — the difference is clearly audible in a direct comparison.

Who is the pow1 for?

For any frérot owner who wants to extract that last bit of performance — and it's the most sensible upgrade before considering other components. Straight talk: the pow1 fits the frérot exclusively. The DAC 1 Mk II, DAC 2, and the Mountain line already have their power supplies built in — it's not meant for those. And if you're already eyeing the DAC 1 Mk II anyway, you can skip the detour via the pow1.

Our verdict

The pow1 isn't an accessory gimmick, but a genuine sound booster for the frérot. At HD Zürisee in Wädenswil, we'll tell you honestly whether the upgrade is worthwhile in your case, or whether your budget would go further elsewhere.

Frequently asked questions

Does the pow1 fit every Merason DAC?

No. The pow1 is developed exclusively for the frérot. The DAC 1 Mk II, DAC 2, and the Mountain line already have their elaborate power supplies built in and can't be supplemented with it.

How big is the sonic improvement?

Clearly audible: a calmer background, more dynamics and body. Several magazines credit the frérot with pow1 with a jump to the next class. You'll judge it most honestly in a direct A/B comparison.

Do I need tools to connect it?

No. You connect the pow1 and frérot with the included cable, plug in the power cord — done. The old plug-in adapter can disappear into a drawer.
