Popular Post MagnusH Posted March 16, 2021 Popular Post Share Posted March 16, 2021 I am thinking about switching DAC to a R2R with I2S input, and then I would like to use I2S instead of USB. The DAC I am thinking about is Musician Pegasus which has I2S as a HDMI (LVDS) input. I am also using HQPlayer so the solution has to support NAA. I currently use a tweaked/upgraded microRendu behind an opticalModule (fiber in), and run NAA on the microRendu. An easy way to solve I2S with streaming would be to just buy one of the USB -> I2S converters out there like Matrix SPDIF-2 USB. https://www.audiophonics.fr/en/digital-interfaces/matrix-x-spdif-2-usb-interface-xmos-u208-32bit-768khz-coaxial-aesebu-i2s-hdmi-lvds-p-11975.html Another option would be to use some quality HATs with an RPi, like the reclocking module with the I2S transport module from Ian Canada: https://www.audiophonics.fr/en/dac-and-interfaces-for-raspberry-pi/ian-canada-fifopi-q3-ultimate-fifo-reclocker-module-pcm-32bit-768khz-dsd1024-dop-p-14758.html https://www.audiophonics.fr/en/dac-and-interfaces-for-raspberry-pi/ian-canada-hdmipi-transmitter-i2s-dsd-dop-to-hdmi-p-13982.html And then upgrade clocks to something good like the ACCUSILICON AS318-B. I use LiFePo4 cells as power (pure cells), 20Ah, so I have power source covered in either case. But which solution will sound best? In principle I like the RPi solution best since it totally gets away from USB, but actual sound quality is of course more important than preferences like that. MgP2804 and 87mpi 1 1 Link to comment
cpasmoi Posted March 17, 2021 Share Posted March 17, 2021 Hello I asked myself the question also and I left on the Pink Fau I2S solution which connects the DAC Audio GD R8 in version R2R, one is capped in the PCM 192 MHZ but it is that of happiness, the DSD 128 in USB does not reach this spatial listening. cdt Link to comment

kvad Posted March 20, 2021 Share Posted March 20, 2021 Interested to know which HAT you go with if you choose to go with the RPi. I'm in the same process, setting up an i2s source for the Pegasus. A safe bet seems to be the PI2AES, but there is also a similar AK4118 based HAT at Audiophonics selling for substantially less. 87mpi 1 Link to comment
AudioDoctor Posted March 20, 2021 Share Posted March 20, 2021 Roon and HQPlayer to an Aqua Acoustic Linq is probably the best. No electron left behind. Link to comment

Yes, and a Lampizator DAC, D'Agostino power amps and MBL 101 X-treme speakers. And then you look at the cost and the dream evaporates like mist on a sunny day. MgP2804 1 Link to comment

MagnusH Posted September 28, 2021 Author Share Posted September 28, 2021 I read a test where pi2aes got stellar measurements, even better than a $1000 Denafrips Hermes DDC. If going the RPi route, do you guys think this is the best route? Link to comment

If going the RPi route, do you guys think this is the best route? Yes, do it, it is excellent, not only for the price. IMO it benefits from a good power supply (I have it surrounded by a Hypsos and an ENO filter, and it keeps well up with these guys). I use AES out, and i2s should be even better. Pi2design has a new model coming out around now, they say same sound but complete in a box. MagnusH and sonodynesrp205 1 1 Link to comment
MagnusH Posted October 26, 2021 Author Share Posted October 26, 2021 The problem with PI2eas (for me) is that I use HQPlayer, and to get best sound you should up-sample to the limit of the DAC which in my case is 16 times (705,6/768 khz) which is not supported by pi2eas. A similar solution from Ian Canada will become a little more expensive (several cards required) but does provide with much higher sample rates (including DSD up to 1024). Link to comment

True. I also find the Ian stuff interesting. But it also sums up a bit, with ucconditioners, fifopi and what not. I believe he went all in on batteries, but found supercaps were a big improvement. If you want the best he offers you'll need that as I understand it. But it could be worth it. I just talked to someone who had the full Ian stack (don't know if also with caps, but at least the batteries) and found he liked Ifi zen stream better. I guess a lot has to do with synergy. I couldn't resist that so ordered at zen to test, with option to return. Unfortunately it doesn't have AES out (or i2s for you), which is the best input on my dac, so I think it's a bit handicapped from the start. Hopefully I'll be either even more happy with pi2aes, or happier with the zen, so no matter what happier ;-) You could do the same, test it or the matrix out. It's difficult to predict. There is also the Singxer SU-6 that seems amazing, with i2s. Link to comment
