Wyred 4 Sound tease PS-1 modular linear PSU, streamer at RMAF 2016

  • It’s the little things that count. In digital audio, we might take Wyred 4 Sound’s Remedy to crack a S/PDIF stream into line or apply their Recovery to re-clock the USB output of a PC or Mac. Taking these widgets themselves to the next level usually means ditching their switch-mode wall-wart in favour of a linear supply. For Recovery and Remedy, a pair of 9-Volters would be required.

    For chop-n-changers in the audio world, this presents a conundrum. Move to another third party re-clocker, streamer (or phono stage) operating on a different voltage and a fresh linear power supply is also required. AURALiC’s Aries Mini likes to see ~15V. iFi’s S/PDIF iPurifier sucks on a 5V pipe.

    Introduced at RMAF 2016, Wyred 4 Sound’s PS-1 is a modular, discrete, linear power supply that can juice up to four devices independently and simultaneously each with either a 5V, 9V, 12V and 15V feed. Current supply from the internal R-core transformer says hello at 1.2A per module. Talk about flexibility!

    Here we see company CEO and lead engineer EJ Sarmento introduce us to this rather natty new device:

    When it begins shipping in early December, the PS-1 will sell for US$499 and will land with a single module pre-installed. Additional modules are presently pegged at an introductory price: US$125/module.

    Sarmento is also working on a network streamer that will interface with his existing MS-1/MS-2 music servers, a direct-connected USB hard drive or serve as a Roon Ready endpoint. Target price = US$499.

    For the average manufacturer, two new products like this would be the main event for good while. For Wyred 4 Sound however, such innovative product line extension come on top of Sarmento’s ongoing commitments to his own Class D-leading ICEPower implementations, OEM contracts, a continuation of James Bongiorno’s Spread Spectrum Technologies and the development of an in-house cooked Class D module that will feature in the company’s forthcoming Statement amplifier.

    If there is a more talented, innovative young gun in audio land, I’ve not met him.
