Is Wyred 4 Sound's Sonos Connect upgrade worth it?

Apart from all else, what does the mod do to reliability? Sonos warranty obviously will no longer apply.

According to Wyred4Sound the mod is warrantied for a year and if you buy the entire unit (connect+mod) from them then the Sonos and the mod is covered, by them I expect. I would also expect, as you said, Sonos would tell you to take a hike.

My connect was many years old so...

Fair number of connects floating about on Craigslist these days so picking one on the cheap and doing the mod is an option.

Great. Now try it double-blind after level-matching within 0.1db, and get back to us... If you still hear a difference, they're coloring the sound, never a good thing.

Jitter is a measurable variable...certain types of power supplies are lower in noise noise than others...but it is not always financially advisable to pay for the best money can buy.

One may not reason himself out of a situation he did not first reason himself into...

Below a certain threshold, jitter is inaudible in any properly conducted double blind test ever tried. This is a fact. Audible noise from a properly performing power supply being present in a digital playback stream has never been shown by any properly conducted double blind test ever tried. This is also a fact.

Interesting thread. I've considered the Wyred4Sound mod also. I have the Wyred4Sound STI-1000 amp, and it's far better than either of my other amps, one of which is a golden-age Sansui AU909. For most non-critical listening the Sonos Connect isn't bad, but since I already had a TEAC DAC, I ran the digital out into the TEAC (UD-301) and then ran a balanced (XLR) connection to my amp and it does have a better sound than using the Connect's audio output to my amp's RCA connection.. I'm not going to use silly descriptors of the difference but the sound is less tiring to my ears. I just don't know if I should pull the trigger on an upgrade while new streaming (like FLAC with MQA) is still such a young technology. It would be nice if we knew whether the onboard DAC in the Connect, a third party mod, or a new bit of hardware all together will be needed to support the new formats in a cost-effective way.

I usually just procrastinate on upgrades anyway.

My vote is for this option.

As usually people on this forum are freaked out that something could better.
It's really obvious where Sonos' weakness are and the Connect is pretty lame for the price especially slice it has never been upgraded. Sonos just keeps milking those ancient products.
Are some of you really that insecure in your purchase that Sonos can do no wrong even when it's obvious how far behind they are in so many ways?

Are you so naive to be gulled in by marketing targeted to audiophiles?
There is a reason for the invention of the word "audiophools".

The Sonos Connect is a great piece of kit, but sound via the RCA outputs isn't the final word in audio. A $550 dollar 'upgrade' to it is insane though IMHO! Mine is connected via co-ax to my hi-fi via a Musical Fidelity V90 DAC, which provides a definite improvement in sound over the stock RCA outputs, at a very modest price. The V90 is one of the best affordable DACs available, period. There's more detail and transparency, and better soundstaging and instrument placement with the external DAC vs the Connect's RCA outputs. I couldn't tell the difference between my current setup using 44.1/16 FLAC ripped CDs from a NAS and the original CDs played on a Resolution Audio Opus 21 2-box CD player, so I sold the CD player. I don't consider myself a 'golden-eared' audiophile - I have a very nice hybrid (tube preamp/transistor output) integrated amp bought second hand, modded a little by me and fitted out with better tubes. I build my own speakers (a good design made at home will wipe the floor with commercial products costing many times more), make my own interconnects and my own speaker cables. I like to try stuff out and won't keep something that doesn't sound better no matter how much it cost me. Some might argue that the Connect is limited by its 44.1/16 sample rate for lossless files, but I'm yet to be convinced of the difference in sound between CD quality and any of the so-called hi-res formats. Mathematically, the differences boil down to minute potential filtering artifacts. Audibly, I've yet to hear them....
