For sale is a Sonos Connect unit that was modified by Wyred 4 Sound with upgraded internal components to deliver audiophile-grade sound quality. For any music lover who desires the best in sound quality yet still wants the convenience and reliability of Sonos streaming audio, this is an ideal solution. This unit operates via the Sonos S1 app. I had sent the unit directly to Wyred 4 Sound for the modification, at a cost of $550. Details of the midification: Sonos Connect with Wyred4Sound reclocker modification A versatile music streamer equipped with a high accuracy direct I2S upsampling digital coaxial output Technical infoThe Wyred4Sound Sonos upgrade entirely replaces the mediocre Cirrus Logic CODAC and the associated high jitter clocks. The upgrade consists of installing a new custom Wyred 4 Sound designed PCB that contains:High-end sample rate converter made by TILow jitter clock with less than .5ps jitterLow noise power supply for the clock and SRMicro processor controllerInput & output digital buffersThis new custom board is factory-installed in the SONOS and directly converts the I²S into up-sampled SPDIF. The resultant ultra clean low jitter signal is then available through both the Coax and Optical digital outputs. While Sonos doesn’t play hi-res material natively (up to 48kHz and 44.1kHz natively), the W4S board’s SPDIF output’s sample rate can be factory configured to 44.1, 48, 88.2, and 96kHz. Note: W4S set this unit to output at 96khz Includes original Sonos Connect packaging. Ships via UPS

Selling a lightly used - Wyred 4 Sound ISO Recovery (black) with an iFi iPower X (5V) power supply - W4S USB OCC cable (1m) If you’re keeping track, that’s a $250 device, with a $100 power supply, with a $100 USB cable. You’re saving some money here. - Yes, the iPower aftermarket power supply makes the ISO Recovery sound night and day better compared to the stock power supply (which I put in the trash where it belongs) - Yes, the ISO Recovery has galvanic isolation and it works very well. If you can hear computer/electronic noise through your USB input, this will solve that problem. And the reclocking functionality works VERY well. It’s the kind of thing that once you hear the sound quality improvement, you’re like oh… I don’t ever want to go back. It’s a big jump. - Yes, that’s the real PCOCC Premium USB cable W4S sells for $200 list, $100 sale. You’re in luck because it’s got at least 150 hours of use on it. Nice and burned in. (I was previously one of those people who didn’t realize how USB cables do affect sound quality. Then I upgraded my crappy printer cable to an OCC copper cable. Well, I was surprised at how much better it was.) Anyway, I’m selling because I need to get rid of some of my gear. If you’re interesting in dipping your toes in the world of optimizing your USB audio source (a very, very deep rabbit hole… sigh), this is a great (and cheap!) place to start.
