Hi
Didn't find a thread about it. We all know that rpi has usb/lan in one chip. I know that with usb to ethernet adapter the lan speed is almost doubled. But what about SQ with onboard rj45 vs usb to ethernet adapter? And if we go further, we can power the adapter from different source.
Like this way:
lpsu1 -> rpi
lpsu2 -> usb dac
lpsu3 -> usb lan adapter
Have you tried? Have you measured? Have you listened? What do you think? 🙂

With my original Pi more noise appeared with any additional wiring.
With my current Pi3 I get noise through my USB sound card when the Pi3 is doing something.... Most noticeable when there is no music playing.
Separating the computer side of things from the audio power and rendering side of things seems to be the way to go. The ALLO Kali and Piano or the full Vana player is one approach.

I've never heard any noise from different pi setups with oem or lpsu psu.
I've used pi1/pi2/pi3 with hifiberry/iqaudio/audiophonics/hdmi and of course with usb dac's.
Worst SQ I managed to get out from inexpensive (5-10€) chinese usb dac's, but never heard any noise.

So if the usb ethernet is a lot faster than on board connection, maybe it sound better also? 🙂

It's a cheap USB sound card... CM6206LX based....
I get digital "chirping" when no music playing. Using a powered USB hub makes no difference.
On the same Pi3 I have a (currently not configured) PCM5122 HAT DAC.... A Chinese one. No noticeable noise through that.
The amps in use probably contribute. They're unmodified 4xTPA3118s from Sanwu. I've yet to get the gain mod done... Hence I usually play music at 2-4% of the volume dial. 🙂

I tried with Belkin USB3 to gigabit ethernet adapter. Network speed doubled indeed, I saw speeds 14-16MB/s and I heard SQ improvement, but it's unusable. Limited/shared USB bus bandwidth seems to be the problem. 16/44.1 flac plays but every now and then it stops for a half second. It got worse with 24/96 flac and completely unusable with dsd.
I'm running a $10 USB3 Gbit adapter since quite some time.
Speed goes up to 300Mbit/s - that's what I measured.
I also had a USB filter (AQ Jitterbug) around that's been sitting idle for while.
I hooked that one up to potentially clean things up. Always good to get the noise down. For sure I wouldn't buy that device for just this purpose!
If you'd e.g. run LMS on this machine or if you bulk-load files, that dongle
at 300MBit could make a nice performance increase.
I wouldn't run it with another USB device such as a USB-DAC though.
The whole PI USB/ethernet arrangement is IMO all but well engineered.
(Onboard Wifi and BT is even worse though!)
A Pi-HAT DAC and that adapter will do fine.
Obviously your preferred OS has to provide the driver and has to be configured to support a 2nd ethernet port.
Then it also makes sense to shutdown the onboard interface if you got the dongle up'n running!
Enjoy.

My Marantz USB-DAC works great with rPi3. Better than with Hifiberry digi HAT. Async usb is better/superior than spdif. Spdif is 30 years old standard. But as always, not all cheap usb dac's are good/better.
What noise are you talking about? I hear no noise, also usb voltage is very clean with diy lpsu <100uV.
Also Archimago's measures show no noise:
Archimago's Musings: MEASUREMENTS: Raspberry Pi 3 as USB Audio Streamer (with recommended CRAAP config & TIDAL/MQA arrives)

Jeeze.
People continue to quote this guy and his nonsense.
He never measures any differences, he never hears any differences and he never questions his measurements and he never questions his system.
Even if people tell him how wrong he is, he continuous do it his way.
Yep - that's what I'd call a role model for all the ignorance out there.
Enjoy.

So you got measurements that show noise then? Or please show some other measurements that show he is wrong and he's graphs are made with ms paint.
It seems, that you can't trust no one, only yourself.

Take my comment as a starting point for you to question what this guy is doing.
While doing so, you'll step over very interesting things.
One thing will be that all these "bits=bits, it's all digital" fraction loves this guy
and his conclusions.
I promise, your learning curve is gonna be quite steep - if you seriously look into it.
Enjoy.
Sorry folks.
Back to dongleing.

You didn't answer my question. Just your word against him.

I admit to having zero Raspberry Pi experience. I have an OrangePi. I don't know if the internal architecture is all that different, but the half-second dropouts I fought turned out to be in the network server's itself, when I changed from running the archive on my Solaris system to a Linux system, all the dropouts stopped.... I'm using a cheap 7.1 USB DAC, and hard-wired 100 mbit network....
