The Sonos plug is too wide? Is it a standard C15 plug?

Can you put up a picture of the plug?

JohnThomas,
I'd recommend this; just be sure to get one that is at least 14 AWG like the one shown.

Its best to plug the Sonos' AC to DC adapter into a separate power strip from the power distributor used for your audio gear and also keep the Sonos away from the Main Audio rack as much as possible. if you use a separate power strip, you won't need the adapter cable.

This is because the Sonos uses is the dreaded switch-mode power supply aka SMPS , the impact these have on high-end audio components is ghastly, and you don't want these anywhere near your audio gear and certainly not plugged into the power distributor that powers your main components.

Switch-mode power supplies cause the dreaded low-source and high-source impedance leakage currents and do all sorts of harm to digital playback, including increased clock phase noise and jitter. The impact of these noise components is quite audible.

if you know the current and voltage for SMPS for your Sonos, you can order good quality and clean linear power supply one matches the current/voltage specifications from Jameco Electronics. Then use the adapter cable referenced above and you can plug that into your Denali.

Shunyata should have an option for the V14D to terminate with a female NEMA for devices such as this Sonos and NVIDIA Shield TV. So like the Venom Extension / VENOM EXT but also with NR.

I'd second PumaCat's post on getting a real LPSU for the Sonos. Especially if it interacts with your system in any way as a streaming source.

The next best thing is a quiet switch mode but you still need to check the voltage and DC current. I'm not sure it will fit the orientation of your Denali, maybe the end outlet(?)
I can't link yet but it's called the ipowerx from ifi audio. It's their new one and not superexpensive.

Myself use the HDPLEX LPSU (200W) because it's so versatile and can handle everything from 3-19V even with higher currents if needed. It can also power up to 4 devices on different voltages simultaneously.

I don't know about the new iFi, but if its like the iPower, its also a switch-mode power supply and most importantly, spews out a lot of high-source impedance leakage current.

Its best, easiest, most effective and cheapest to just get a Jameco Reliapro regulated linear power supply for...$11.

Yes, but be advised if you connect your Sonos directly to your DAC via USB, etc. and still use the stock SMPS adapter, you will still be sending high-source impedance leakage current to your DAC from the dreaded SMPS, and the impact of this will be increased clock phase noise, which is sonically deleterious and audible. If you want reference that is more in-depth as to why, just let me know and I will post a link to the reference.

Johnthomas, most of us in this day and age have digital sources. But just upgrading your PSU will reward you with higher SQ.
Denali is good at handling noise but if you can lessen it to a high degree just by exchanging a stock SMPS to LPSU or even the ifi xpower this will benefit all plugged into Denali.

If Sonos is your music source then it really should be on the Denali, it should benefit the end-result, but try to lessen the noise load first... :=)

Question regarding the use of V14 adapters with C5, C7 connectors.

For primary sources/streamers, is this a true statement?
A Shunyata Alpha V2 NR connected with V14 adapter and C5/C7 outlet will always surpass a straight V14D cable with C5/C8 connector on audio/video streamers regardless if the electronics have internal LPSU or SMPS?

Will they sound close/identical or will the class difference be apparent in a reference system?
