Title: Introducing ApplePi DAC -- Highest Performance Raspberry Pi DAC
Post by: orchardaudio on February 04, 2018, 11:30:23 AM
I will soon be launching a new DAC for the Raspberry Pi. It will be called ApplePi DAC.

With the upcoming release I am also looking for reviewers.

If you are interested in reviewing please contact me with the following information:
1. Where will the review be published?
2. How many visitors do you expect to have visibility of the review?
3. How long will it take to do the review once you receive a unit?
4. Have you done other reviews of Raspberry Pi Products, do you have any links to examples of your work?

Questions/Comments also welcome.

Price: $200 USD, at launch available for $175

Check out the first ApplePi DAC review by The Audio Beatnik​:

"Ok, specs are great and all, but how did it really sound? Frankly, very good, surprisingly good."

and

"The mid-range and truthiness of the music rivaled that of the other DACs I have on hand that cost significantly more."

I realize this is blasphemous... any plans for a single ended only (non balanced populated?) version to help bring down the price point?

Post by: tmazz on March 17, 2018, 08:41:32 PM
I realize this is blasphemous... any plans for a single ended only (non balanced populated?) version to help bring down the price point?

The full retail price of this board is only $200. How much could it possibly go down?

I am willing to bet that the start up costs of doing a second separate production run and the costs of maintaining dual inventories would more than wipe out any potential savings that might be had from a simpler circuit.

(Not trying to bust your b@lls, but product costing and pricing is what I have done for a living for the past 25 years so I have developed a pretty good gut feel for these kind of things.)

Where's the ball busting emoji?

Having an alternate BOM where certain components are populated or not is not rocket science. A simple "That is not in our plans at the moment" would have sufficed.

Let's argue for a moment that the current implementation is targeting a "higher" end user. If he were to get down to $120-ish range, might he be able to take volume from someone who would look at one of the other Pi Hat options? I wouldn't expect huge delta's in fixed costs by supporting 2 builds, so would (bad assumption?) uptake in volume for hitting the lower end, while also hitting the upper end drive possibly larger quantity buys (lower part costs)... maybe there wouldn't be that much of a delta in volumes so it's not worth it.

I realize in some eyes it's "only $200"... another way to look at it is that it's 2.5x-3x "comparative options".
<edit>Not suggesting it's not worth the extra money. I do hope he sells a crap ton. I'm only asking if the thought had crossed his mind.</edit>

Perhaps I read too much into "Questions/Comments also welcome. (http://www.audiocircle.com/index.php?topic=155479.msg1663797#msg1663797)"?  :roll:

I had considered a cheaper version, with no XLR connectors and cheaper operational amplifiers. But cheaper would not be $120 it would still be more than $150. I figured that's not enough of a cost difference.

Just removing the xlr connectors would make it 10 dollars cheaper.

Any significant cost reduction would also significantly hamper performance, and would result in more then just BOM change.

Would anybody here be intrested in being part of an ApplePi DAC tour.

Basically you get to use it for a week and then you ship it to the next person, then hopefully post your feedback and thoughts.

I currently have 5 people from another forum, The board will be shipped out to the 2nd person next week.

Let me know if you are intrested or have have any questions.

Here is the first user review:
http://www.audiocircle.com/index.php?topic=155479.msg1677776#msg1677776

"I highly suggest that folks sign up for the tour to hear this wonderful device.

I spent a good week listening to it and came away extremely impressed with what Leo has done with this DAC hat.

For anyone that is using a Squeezebox Touch or similar unit, they should find this to be an quite an upgrade.

I did compare it to a DAC I built with AK4990 DAC chip and Salas shunt regulators DIY modular DAC
I really could not pick one over the other. The sonic difference was completely dependent on the file being played. I feel both units are very transparent.

For under $250, the combination of a Rpi and the ApplePi DAC board is an outright bargain in today's audio world.

When it is released, I will be buying one."

Hello, Leo.

I have some questions for you:

1) Is this compatible with my Mac Mini (Apple Computers)? Is this compatible with my iPhone or iPad?

2) Eventually, the touchscreen will die or malfunction (most likely before the Pi suffers indignities). Is the touchscreen user replaceable?

3) Eventually, the touchscreen maker will stop producing this unit, what options would I have if my touchscreen dies after it is no longer available?

4) If I back this product only to discover I don't like how it sounds, may I return it for a full refund?

5) Is piCorePlayer compatible with Apple Computers?

6) It appears the 'Pi' portion is open to the elements. Is there a housing to keep dust out? Is it necessary?

7) How does this DAC differ from the DAC prototypes that Tommy sent me a couple years ago? [This should be directed to Tommy, I suppose.] I ask because I did not care for
    them. If it is materially the same, I will have no interest in your product. (Sorry, but honesty is best.)

I look forward to your response.

Regards,

Michael

Looks really good Leo. External HW clock great idea!

You mentioned the DACs are TI PCM1794A, nice choice. The pictures of the PCB on your kickstart page are still too small for me to read the opamps for the dual diff output stage. Can you name which output opamps you are using? It makes such a difference as I'm sure you know. Thanks

The Op Amps are OPA1612

Starting to get some feedback from kickstarter backers:
Kevin:
"ApplePi DAC is an excellent DAC. Compare to the Audio Note DAC 3 I have, it has much more detail."

Here is a review that was just posted on diyaudio:
http://www.diyaudio.com/forums/vendor-s-bazaar/321303-applepi-dac-performance-raspberry-pi-dac-post5520363.html (http://www.diyaudio.com/forums/vendor-s-bazaar/321303-applepi-dac-performance-raspberry-pi-dac-post5520363.html)

I was part of the ApplePi tour and want to share my impressions of this DAC.

HARDWARE

I tested the hat with Rpi 3B, IanCanada IsolatorPi, and Allo Kali. Each board had separate power: I fed the Pi with an iFi iPower and the other three boards each got a GStew modified Jameco linear wall wart. Listening environment was a rather analytical nearfield desktop setup--a Tripath amp into some Axiom 2 way bookshelf speakers, and a humble full-range setup using another Tripath amp with Aura NS3 drivers.

First surprise: This DAC seems to be immune to PSU noise! Other DACs I have tested are all very sensitive and exhibit hum and hiss to some extent, even with an isolator board, Kali, and four separate power supplies with earthed ground rails via John Swenson Ground Tweak. Using these careful measures, I have been able to reduce noise by, say, 95% with the other DACs. But I can still hear a tiny bit near the speaker when music is stopped and I crank the volume knob to max. 

In contrast, ApplePi is silent. Even if I float the PSU grounds by unplugging my earth wires from the negative terminals...it stays silent! The other DACs would be intolerably noisy this way. I'm impressed. This could make getting good sound from a Pi a heck of a lot less hassle and expense. 

(edit: Since this test I have booted the iPower out of my setup completely, and going completely linear in combo with the IsolatorPi killed noise at the speakers almost 100% for any DAC Hat on my Pi stack )

SOFTWARE

I played music through the ApplePi with both Moode and Volumio. I was not able to get 16/44.1 files to play natively on ApplePi with Volumio, though Leo told me this works for him. It did play 24-bit files quite nicely, but everything in 16-bit I had to upsample...and IME Volumio upsampling sounds sort of lifeless. Thus, I spent most of the time playing my music collection (which is 95% Redbook FLAC) via Moode, which worked flawlessly, natively decoding all bit depths and sample rates I tried.

SOUND

One huge advantage this DAC holds over all others I have tried is the beastly 2.5V output--it just makes both of my amp/speaker combos sing, almost like having a preamp. This results in some of the best, most effortless bass control I have heard in my systems to date. I wish every source component had such gusto. In both my systems, ApplePi made my little flea-powered Tripath amps able to push significantly more air from the woofers without distortion. (Note to self: buy a real amp). IME good gain staging just makes everything downstream happier. Take note: the board gets quite hot. Leo said he has made some revisions to help dissipate heat better with the production boards. 

Entering into highly subjective territory, now. My listening impressions parallel my experience with Alex's DIAL_DAC to a great extent...the sound signature shared between the sibling Burr Brown chips is evident. Analytical and smooth at the same time--detailed without harshness. Especially with 24/192 files, transparency is excellent. 

I feel that the powerful, controlled bass and detailed treble are the most apparent and expressive parts of the music with the ApplePi. At this point I have to reveal myself as a total sucker for midrange body and warmth. Thus, the ApplePi doesn't push all my buttons...in fact, I'd say it stands in slight contrast to the meatier tonality of the TDA1387 DACs which usually sit atop my Pi stack. Which flavor you'll prefer will surely depend on the other gear in your system as well as your personal taste. 

Nice job, Leo.

Case for ApplePi DAC...

Thanks to one of my customers (Rick D.) I can say that the HifiBerry Universal Case, fits the ApplePi DAC perfectly:
https://www.hifiberry.com/shop/cases/universal-case-black/

I would highly recommend getting these heat sinks for the DAC chips:
https://www.newark.com/fischer-elektronik/ick-smd-a-8-sa/heat-sink-dip-ssop-tssop/dp/34M6428

In addition to the heat sinks I additionally recommend drilling a few holes in the top cover to improve airflow.

The case will not work with ApplePi Volume-Clocker.
