Raspberry Pi HiFi DAC Pro Hat ES9038Q2M Audio Card PCM DSD Lossless High Resolution Digital-to-Analog Converter Adapter for Raspberry Pi 4 3B+ 3B Zero w Zero

Excellent sound quality for th eprice, decent headphone amp too. Used on RP3b, RP4 and RP5. Used with power conditioner and without. A tad better with conditioner. Works flawlessly with Moodeaudio

Much better audio quality compared to other PI DAC Hats I have tried. The IR receiver component is not fitted.

I have 2 of these hats. One on a Pi 5 and one on a Pi Zero W. Both are running Volumio v3 with an SMB share to my NAS for the music library of mostly FLAC cd rips and some high-res downloads. Simply selecting "Allo Katana" as the I2S dac was all that was needed to enable. The Pi 5 works great with just the 5v 5a DC power supply from geekworm. I used the balanced audio outs to my Behringer mixer to ATH-R50x headphones. I was amazed listening to most of my audio tracks and how much detail it was pulling out. Can't say if wifi worked or not as I had a wired network connection. For the Pi zero w, I found that using just a simple 5v 1a phone charger was limiting. I connected a dedicated jameco linear 5v wall-wart to the USB-c on the hat and removed the power sharing jumper. Bass specifically was much more defined where it was muddy and weak using the phone charger. I connected the stereo output to a JDS Labs element for headphone output which sounded great. I did have a problem with wifi connectivity. I have an aluminum 52pi case on the zero with this bare hat on top. The wifi on the zero was basically un-usable so I used a usb wired ethernet adapter. As an aside, Volumio 3 is really a hard lift for a low cpu-power device like the zero. The audio worked fine, but waiting for processing to complete such as importing a library was super slow. I would highly suggest a pi3 or zero 2 as the lowest spec if you want a responsive Volumio UI with this hat.

Good...Ok.... 3.5 mm output only working.

It sounds somewhat cold and harsh compared to the Iquadio dac pro on my Genelecs with 3.5mm to XLR balanced input. I tried linear powersupply and powering the dac standalone.

In gebruik als PiCorePlayer in combinatie met een Pi 3 Model B Plus. Spacers worden geleverd om deze HAT stevig op de Pi te monteren. Deze kaart heeft 3 manieren om voeding te krijgen. Twee werken niet in deze combinatie en een aparte 1A voeding voor deze kaart is noodzakelijk. Dit is overigens een pluspunt. Ik heb mij ietwat verkeken op de audio aansluitingen; vanwege het ontbreken van XLR op mijn versterker deze nu aangesloten met een phone-jack to RCA kabel. Ik kwam erachter dat de service van inno-maker uitstekend is; een vraag hierover was de volgende ochtend beantwoord. Citaat: "Get single end signal from headphone to RCA is the correct way to use it. it wouldn't cause any quality degrade." Het heeft dus geen zin om moeilijk te doen met extra conversie kabels XLR to RCA (scheelt weer minstens €30). Het geluid is in eerste instantie wel zacht. Dit kan worden verholpen met een correcte instelling van de Salsa Mixer door deze op 0db te zetten. Tip zet wel eerst het volume van de versterker weer terug. Hoe is het geluid? Goede vraag dat laat ik aan de deskundige over. Ik gebruik deze combi voornamelijk voor Internet radio. Wellicht overkill maar een goede basis voor de toekomst.

Works well and I can recommend it. I plugged it into the Raspberry Pi 3 and installed Moode. Configuration was easy and it worked immediately. The sound quality I found very good although audiophiles might want something better.
