How many folks purchase a RPi, use the USB out and purchase a USB to S/PDIF converter? There is only one reason I use one - I have to. Unbeknownst to me at the time, the USB 2.0 input on the ARC DAC required a Windows based driver. Just recently, I got notification there is an upgraded board that supports Mac, but when I asked about the uRendu, the response was it doesn't support LInux. Gee, I thought Mac OS was essentially a Linux core. Go figure.
I've already observed the disparity in cost and specifically mentioned that perhaps what I'm really hearing is power supply differences.
Gee guys, I'm just comparing systems that folks might put together, not dissecting each and every piece. Maybe someone should compare a naked board to an acrylic one while they are comparing everything else under a microscope.
I am open to any further suggestions as to kernel settings that might prove to be beneficial which don't sacrifice usability or stability. I mentioned the buffer and hdmi_blanking to Sounchekk and since he did not respond, silly me I thought that meant there wasn't anything else. Now he's talking about disabling the LEDs?
Perhaps he or others might put together a complete list in a single place!
Actually I use my RPi with USB out.
My Dac has a self powered Amenero board inside. Meaning its essentially the same as having an outboard USB converter with I2S output....which is what the Amenero feeds the Dac as output.
The pic you posted of your RPi in DAC box on the 8th(sorry I'm traveling and embedding link is trickier with pad)
What I see is an RCA cable coming out of what looks like my HiFiBerry Digi+!
Edit: especially with spell corrupt :)
I have 4 RPis..... Two with Digi+ pro and to without
What are your observations between the two approaches? Do you use both because neither offers an sonic advantage?
Sorry for all the questions, but presumably this is the kind of information decided noobies to the Pi thing like me seek.
Initially I purchased the RPi to use with my Master 7 Dac. Again because it has its own self powered USB to I2S card my intentions were to only use USB out.
I purchased a Digi+ to see what all the hype was about. It was okay [just okay]. Ended up using it for my Pie-in-the-Box project with the RPi inside of the Dac….spdif out.
Then they came out with the Digi+ Pro with the two clocks. Again I just wanted to see, so I purchased one…it was much better, plus I could use it to power the RPi directly.
So I purchased a couple more RPi's, one for my tube Dacs and one for my Master 7. I like the sound of the Digi+ Pro vs. USB in my Havana tubed Dac so I ended up with
2x Digi+ Pro and a RPi for USB out to one Dac.
Sound wise I like feeding my Master 7 Asynch via USB, and letting the Amanero convert it to I2S.
I like feeding my Havana spdif over USB and I was forced to use spdif for my project.
Just when someone puts together a complete list, they'll discover a new planet along with different gravitational forces acting upon your Pi. It's a losing battle. Your system vs system comparison approach was just fine by me and probably not as susceptible to micro perturbations like individual components, LED's included. ;-)
Sure, system vs. system is fine. Just as long as its understood that you are not comparing one individual part of the system.
Usually when a comparison is done people try to eliminate the variables so that only the 'two' things being compared.
Dependent Variable = Sound
Independent Variable = Streamer
Estat Independent Variable[s] = Streamer + Power Supplies [Wallwart, HDPlex] + USB Converter + OS/Software + SPDIF Cable + Digi+ HAT + Music Material ?[DSD etc]
Hopefully any experiment will only have 'one' independent variable and the setup will be identical.
