Raspberrry Pi HiFi Berry vs. uRendu...

because we haven't discussed this issue NEARLY enough...

It seems the uRendu has Gigabit Ethernet input while the Raspberry Ri is 10/100?

Guessing the Raspberry Pi HiFi Berry edition may not support 512 DSD either but I really don't care.

I think a far better comparison regards the value of the Raspberry Pi HiFi Berry combo would be to compare it to a SBT, which it clearly replaces and isn't that what everyone who loves the SBT has been hoping for?

As far as sound quality, I see no real way of an 'apples vs. apples' comparison as the uRendu is USB and the HiFi Berry output is S/PDIF - TOSLINK. At least from my perspective, I'd be comparing two different inputs to my DAC, one of which would be going through the USB > I2S circuitry the other not?

But again, it's something we certainly have NOT discussed in NEARLY enough detail. ;-)

I just converted my dac input from WaveIO USB->I2S to HifiBerry DIGI+ Pro which is essentially Network to I2S.

No looking back.
To infinity and beyond!!!

one is HDMI the other RJ45.

Guessing the the I2S on the HiFi Berry card feeds the S/PDIF converter?

How did you make the direct connection?

THAT would be great for me as my DACs (Audio-GD Master 7 and Master 11) are reported to sound best with a direct I2S input.

I'd like to see that.

If you are going to to I2S you really don't need the Digi...unless you are only using it for the clocks.

Either way, I'd like to see this thing...granted pro audio is fast going to digital via Ethernet...lots of rave reviews esp with the RedNet by Focusrite.

Still like anything else, it all depends on the implementation

Rednet = 600 $ minimum entry ticket for a digital transport. Had its fan club on Head Fi, supposedly sounding great connected to a 1000 $ Mutec reclocker and some high end DAC. The guy who started those threads ultimately went back to a USB setup he claimed sounded much better.

Headfi is a market bait web site.

Manufacturers get someone to post a review and claim XYZ, then everyone buys the product.

Audiogd and Schiit Audio to name a few owe their success to Headfi.

So is this place, but hey...

Lots of happy Audio-GD users on HEadfi.

Here too, it seems.

The HiFiBerry gets I2S directly from the GPIO pins of the RPi and converts it to SPDIF. The board also has pin outs to make a I2S connection as well as pin outs for BNC.

I have one that I soldered a BNC out too and will be soldering a I2S out of the other once I get the parts from Audiogd.

Is your Audio-GD DAC RJ-45 or HDMI?

My first interest is to use the HiFi Berry with the Master 11 which I mostly use downstairs from the listening room with headphone. Ethernet outlet is a few feet away so I wouldn't need a laptop to stream music. From what I understand the LMS user community has a share-ware plugin for streaming both TIDAL and QOBUZ.

I've also been led to understand that the I2S input is the preferred input to the Audio-GD DACs but I have not gone that route as it means converting the USB output of a laptop computer through an additional 'third box' which seems to defeat the purpose of a direct I2S connection.

Please keep up posted!

Correct, the quality of the I2S lines count and they need relocking too!
So it is not the case that anything that transfers via i2S is best. Clock quality into the dac matters a lot and there is no el cheapo implementation.

It's not just HeadFi.

You can't take any site out of the list.

Just think about it.

E.g.
What does this forum stand for?
I'm pretty sure we'd find a common view on that one.

Yeah, I'm just still bitter from being Banned for LIFE at Headfi.

These parts, he has kits that can be used for I2S.

You might checkout what network capacity a stupid audiostream requires to be able to judge the impact of 100MBit/s vs. 1GB/s.

Than you need to know if a device or a network is even able to process 1GB/s properly. That's not always the case!

I hooked up a $10 GBIT dongle to a USB port of the PI. This brought me
300MBIT/s. But. Is that the key issue?
Just in case you bulkload files for RAM playback, it'll give you a slight advantage.

The dongle has certain other advantages though.
1. You'll get the networking HW away from the PI
2. Even those $10 dongles are often better build then the PI internal networking part
3. You could power it externally
4. What I did, I hooked up a Jitterbug filter that was sitting idle between dongle an DAC to clean up the air.


BTW. The PI is very much comparable to a uRendu. The USB ports
can be used as audio output the same way you do on the uRendu.
BUT. For sure the USB output quality of a PI is worse then
a uRendu. That's why I said you'd need to add one of the known
USB gadgets to your bill to be able to get to a uRendu USB performance
level.

...VERY happy with the result. I'm sure it could be improved...but at the moment I can't be bothered.

so the 3,3v is not supplied via the GPIO of the Rpi anymore.
