Raspberry Pi2 and Hifiberry Digi+: A cheap transport that made me happier

FYI the Digi+ PRO it's on the way to me, sure don't see any on board LDO's unless they're underneath.

 

Any onboard regulators... nope:

@Scott: There are no onboard regulators. 5V is only needed for the optical output, all other parts of the circuit are powered by 3.3V.

We don't have a part number for the BNC jack yet, but we will have these available in our shop in the future. They come from a small Czech company.

Best regards,
Daniel


Does have a certain simplicity though, we'll just need to use our LT bla bla bla super quiet LPS's and the driver's already in the official rasppi!!!

 

Well to me I guess it won't make a huge diference since I already have a good psu. Those who don't wanna spend more money than needed would better stick with speed2 IMHO. The performance level with an horrible smps is unbelievable compared to the digi+ due to the onboard regulator.

 

I would, if I could have it, I've been waiting so long, I forgot about this approach to digital playback.

 

@Scott Kramer did you have time to compare the Digi+ with the Digi+ Pro? An upgrade or a sidestep?

 

Hi, i have ordered the HiFiBerry Digi+ Pro ßeta board.
i hope someone will be able to get it working with Moode audio

 

Hi @Eugene du Toit,

Received it just now:

Running perfectly on a fresh install of Moode 2.7 (4.4.19+). On a rasppi A+
Will get serious about sound quality testing once piCorePlayer is ready (looks like that will be soon).

 

Is supplying 3.3v directly to the digi+ with a linear power supply better than powering both the pi and digi+ with a 5v sbooster linear power supply? Where does the pi convert the 5v to 3.3?

 

Just received mine also. I am guessing P3 is still the 5V in, P5 is the 3.3V maybe? What is needed to cut the PI from powering the Digi?

Looking forwarding to getting this up and running. Planing on trying a TPS7A4700 for the 3.3V.

Regards
Bob

 

Looks like Daniel plans to drop the official documentation for 5V/3.3V bypass and i2s after he knows the boards are working. P3 is the same. P5 3.3V will *probably* involve removing R3 resistor, *DON'T* do it yet!

However, I'll use the piZERO with only the pins needed, excluding the 3.3V pins there.

@primeform please read thru the threads, it's been answered in a few different ways. Plus let's see where the PRO takes us.

BTW, the jumper should be removed for COAX galvanic separation. This was probably included for people's DAC's not lighting up (grounding issues) this was a problem on the digi+

 

Hi Scott,

I have it working with the new posted Roon image, 1.06. I am not going to start messing with the board yet, thanks. Is the consensus to stay away from the PI3? I am not using wireless, so I was figuring the PI2 may be a better choice. I know you like the Zero.

Regards
Bob

 

Hifiberry Digi+ PRO up and running on piCorePlayer 3.02 beta ( *the* best option for audio ), listening now on headphones, Awesome!

And still just stock, no LPS, no piZERO, to start.

 

Also big fan of the picoreplayer software.

 

Hi Scott, thanks for this information.
You think I should test Picoreplayer ?
It sound much better than MoOde Audio ?

 

Hi,

i received the Digi+ Pro this afternoon.

i use it on a Pi 3 with MoOde audio.

MoOde recognize it immediately ; only need to reboot.

The Digi+ Pro is plugged with a Lifatec glass toslink on my digital amp QLS QA 100.

First impression, it sound very good .

I thank Hifiberry team for the quality and the value of the Digital + Pro

 

The pi3 is fine, I think it's actually *more* expensive now to get a pi2, there's nothing so special you'd need it over the 3. ( buuuut.... I doubt 2 wireless radios, more power usage etc, is gonna do the audio any favors )

However, if you're serious of course take it all the way with a piZERO

In the pic, that's a 3 I have laying around to test... its built-in wireless was actually hanging up somehow, so could be a software problem or conflict with the PRO, so be aware of that.

 

I have both 2s and 3s but have not seriously listened to the 3 yet. I have ordered a Zero and will be getting it soon. The new Schiit amp in the pic? Cool, what do you think of it so far? What DAC were you using?

I am currently listening to a Modi Multibit with a Pi2 and Pro board. Powering it through the Pi with a linear supply, nothing fancy but sounds very nice.

 

Nice re: the Zero, did you get a kit that includes headers?

It's my first headphone amp so kinda' noobie impressed-- Well PSAudio sprout was 1st, bought it when they did the kickstarter--> but the 60Hz hum in headphone amp made it unusable & never even used it. Sold it, they stuffed too much in a tiny space.

The dac is temporary there (to test the balanced in) it'll go back to my main system. It's a PSAudio DL3, but the cullenIV upgrade... 0ps clocks, output stage etc. It still's very good. The moby will end up on my desk for headphones, nearfields...

I understand exactly what you have there... it's wonderful--

 

...Oh one thing, if the ZERO is too far... basically you'd rather not solder.

A piB+ maybe even A+ is the one to buy for solid everyday use (but awesome quality) wth the Digi+ That's my backup if dicking around with the Zero.

 

Thanks for the A+ suggestion, that's a great idea. The latest one has 512k. I have headers so it should not be a problem soldering the zero. I guess I would only need the I2s connections, maybe ground and no power if using separate power for each. Not having the extra USB ports, and the Ethernet connected to USB looks like an advantage. I am using fiber, when you get a chance maybe give it a try I find it to be an improvement.

I'm waiting for a fiber to USB converter that is compatible, should be here in a few days. Looking forward to trying it.
