To make it work you have to provide MCLK , 2x9 Vac and 2x15Vdc . For this I use Kali Recloker , some voltage regulators ( home made) and 1 trafo.
Architecture: Velvet Sound I2S
THD+N -101dB
S/N 123dB
Digital filters 4
PCM 384kHz
DSD tested : DSD64, DSD128 & DSD256.
Price: 79,00 €
It is working with Terra-Berry DAC2 driver but without hardware volume control. ( If somebody know how to make it work , please help).
I’m set up using Allo.Com Piano 2.1 and Kali reclocker hooked up to the Pi3B+ using Volumio. Works Great. Here is a quick video of it hooked up and working.
see the DACBERRY ONE+ a PCM5142 Master Mode board which sounded very well in my soundcheck…

NanoSound DAC2 has kept all the benefits of NanoSound DAC and made improvements in all areas.
NanoSound DAC 2 - Sound Quality Improvements
2 x Precise crystal acting as master clock for lower gitter and better DSD performance.
They provides very accurate timing for 44.1khz and 48khz respectively, resulting in less jitter and better sound quality. It also let the Raspberry Pi to do less work by not requiring it to generate clock signal, hence less heat and better playback performance for CPU intensive playback like DSD.
Improved and wider sound signal paths
Critical electronics component uses top audio grade capacitors by ELNA, WIMA, EVOX instead of much smaller and cheaper surface mount counterparts
NanoSound DAC 2 - Convenience Improvements
Digital knob style volume control for maximum accuracy
Reusable accessories such as NanoSound Amp^2
Choice of 1.5" OLED Colour Display to display album artwork
Dual power input is now autoswitching instead of using a manual toggle switch
i like the DACBERRY PRO+ a PCM5242 Master Mode board with RCA, Headphone and XLR option…
for volumio use the DACberry ONE+ I2S driver…
from the website:
The DACBerry PRO+ is a High-End Professional Audio Soundcard with a beautiful gold plated and matte black finish. It’s plugs directly on the Raspberry Pi A+/B+/2/3/3B+/4B. Compatible with Asus Tinker board, Jetson Nano and other ones using the same GPIO.
Uses the Texas Instruments PCM5252 as main DAC, featuring balanced output, better Signal to Noise Ratio and THD. With the Linux drivers built in to Raspbian no kernel recompilation is needed, it’s supported by all the most used audio software.
Includes PurePath™ Smart Amp technology, which allows speakers to be driven with more peak power than their average-power rating, without damage to the speaker by voice coil over excursion or thermal overload.
DACBerry PRO+ also includes a 3W Hi-Fi Headphone Amplifier delivering an amazing audio experience for those who listen through headphones. It’s compatible from 4 to 600 Ohm Studio Headphones.
Features the onboard I2C 4 Pin connector for peripherals like the 1.3″ OLED Display with the I2C cable. You can also add the MIDI Extension Board to get MIDI Input/Output.

(same as DacBerry ONE+)
i could tested a prototype of a I2S RPI DAC AMP. a 4 channel x 60W 192Khz Class-D Amplifier that works with the Piano 2.1 volumio driver! Dual Stereo and dual mono! DACBERRY AMP2 osaelectronics.com/product/dacberry-amp-2/
This HAT is working fine with volumio 2.692 version with driver kernel patch.

I like it, similar to the one+ of OSA but instead of digital output a better headphone output.
