Sonos Connect Wyred4Sound Mod Any Good?

Psickerson, I’m using an Exemplar exception DAC.

I haven’t heard a stock Sonos, but I’m happy with the Ultimo upgrade.

I would think it’s no-brainer upgrade for Yggy.

You can by a new Sonos Ultimo from Magna audio and get a 2 week audition period.

Though care has to be taken with the ethernet connection.

I use ethernet power line and when I moved it from the wall outlet to my Entreq Powerus Challenger, there was a seismic leap in performance.

I will be adding a Waversa hub to regenerate the ethernet signal to feed the Sonos.

And upgrade from the cheap ethernet cables I’m using.

Schiits response to my email said to not send an up sample to yggy,. It is better to let it do take care of it.  The only other improvement from the upgrade would the better clock low jitter.  The yggy already says it has s good stream so I don't see how an upgrade to the stock Sonos would be any improvement.   Am I missing something?

Jitter is a big deal. You want to feed your DAC the lowest jitter source possible. 

The power supply upgrade on the Ultimo can't hurt either.

jitter is a major weakness of the Sonos

Yes, that's why the clock is upgraded by Magna audio.

There's quite a bit of noise coming through the ethernet in my setup. 

I hope the Waversa hub will address this.
