If you’re familiar with Chord Company, you’ll know speaker cables and audio cables are its bread and butter. But now it has branched out into new territory, specifically power blocks. The aim? To improve the power supply to and the performance of your home hi-fi system.

Chord Company has introduced two new models available in both UK and European specifications, the snappily titled PowerHAUS S6 and its step-up sibling, the PowerHAUS M6.

HAUS stands for Hybrid Array Unfiltered Supply - these six-way blocks employ different levels of technology to try and eliminate any noise that might ruin your listening experience.

Both blocks use aluminium casings and inside you’ll find three isolated bus bars positioned in parallel in order to try and reduce the effects of high-frequency noise. Wiring is also heavily shielded to reduce the possibility of interference and all the internal cables and sockets have been chosen for both reliability and sound performance.

The S6 uses Chord’s SuperARAY conductor technology, but stepping up to the M6 introduces three of its hybrid MainsARAYs in parallel, plus Chord Company’s noise-reducing GroundARAY technology.

We were lucky enough to be invited down to Chord’s HQ in Amesbury, England to get first-hand experience of both of the new power blocks. Our listening session included switching between the two blocks while listening through Chord’s own reference system.

And, in our opinion, you could definitely hear differences in a number of areas including clarity, resolution and stereo imaging. Of course not every hi-fi system will warrant a £1000 (about AU$1900) or £2000 (about AU$3800) for the PowerHAUS S6 and M6 power block respectively, but if it does, then there's no harm in trying one out, right?

    More snake oil. The special thing about this snake oil being that it's A1, 1st class, top notch snake oil so it commands a premium over other snake oil.

    There are plenty of articles that show measurement of these kind of applications. First of all the mains power is converted to DC in all Amplifier circuits with rectifiers and capacitors sequences ... and it is therefore impossible to occur, yes: it is strange & asburd to think that any noise will make it into the DC supply. There are measurements done on audio equipment without or without a noise main power ... and ... it ... does ... not ... make ... a .... difference. Why does WH not do proper technical reviews instead of saying things like "no harm in trying one out" for £1000-£2000 per piece? Why does WH not proof if this piece of equipment does what it claims? Why does WH not protect the consumer instead of screwing them over?
