RuneAudio with RaspberryPI and DDDAC1794-NOS

[Ahtunowhiho]

Hello everyone,

we (some friends from and near Wien, Österreich) have our little project up and running, and finally everything is like it should be, thanks to RuneAudio 0.3 alpha.

There was only one problem with playing Flac-files, instead of using the Hifiberry-I2S-module we had to use the module snd-soc-pcm1794a, as with the DDDAC1794-NOS the output is mono when playing FLAC-audio-files with our special setup.
It consists of a RaspberryPi-Model-B connected through I²S with a DIYINHK-isolator (for isolation of the I²S-signal between Raspberry and DAC) , which is wired to the DDDAC1794-NOS, designed by Doede Douma (http://www.dddac.com/dddac1794.html), using RuneAudio to play our files (Flacs up to 24bit/192kHZ, Mp3s...).


Here are som pics, for wireless-control there is an Edimax-EW-7811Un-wireless-adapter in one USB-port, the other is used for the external-hdd containing the music-files.
The aluminium-case is from ebay, it was used in East Germany in the 'Abteilung für Rationalisierungsmittelbau' long time ago, but perfect for our needs.

The sound really is unbelievable most of the times, of course depending on the input-file, you can't enhance a bad sound-production/mastering.
But when the input is good the output is awesome, mostly equal or beating the vinyl (of course there also remains the question of origin/production), but this leads to constant discussions between us, one favoring vinyl, the other digital. Let's take the best of both worlds.

So many thanks to the creators of RuneAudio, in our opinion it's the best software for Rpi-Audio right now!

I'm happy you like our work
And thumbs up for the DDR enclosure and the Mundorf jewelry!

I read good opinions about the DDDAC around, could you compare it with something else you previously used?

I post this at Diy-forum when I first leant of RuneAudio with great appreciation. Currently using the Pi without Isolator via Hiberry and it sounds fantastic! I think due to the excellent outcome, many could not help it but getting little impatient for the beta version to come out!

Hi Rune-team,

Currently enjoying RuneAudio 0.3-alpha via Raspberry Pi, and could not go back to my optimised dual PC setup with JPlay. In anticipation for the Beta version to be released, I am currently pulling together a front-end setup using BBB with Acko SuperCape (similar to the Botic Cape but also has UPS and I2S/DSD switching capabilities) I2S output to Acko S03 I2S isolated and re-reclocking to NDK 45/49.xxMhz to my DDDAC. BBB RuneAudio beta will collaborate my setup into an endgame analog-alike setup!

In appreciation from RuneAudio, I would love to assist where's can, however, given my incompetency with Linux..., could be a bit of wasting your/team time. Hence a donation is made!

Many thanks again for the team effort(s)! May the birth of this long awaited beta soon be released into the Rune-fanatics' life!

Warm Regards,
Chanh

I also have an Acko DAC SO3 isolator/reclocker board on order except that I plan to use it with a Beaglebone Black; this will represent a step up from the RPi, (limited as it is by its single 'nothing special' clock), as the SO3 has two high quality clocks (one for 44.1 KHz data family and another for 48KHz data family) that can be fed into the BBB thus keeping data at its native sampling rate. The BBB will need to run the miero driver;

to function and I'm excited to see that Rune plans to include this in the forthcoming V0.3 release for the BBB.

BTW, my BBB/SO3 combination will be feeding a Twisted Pear Buffalo 3SE DAC, which utilises the top drawer ES9018 dac chip in a high quality implementation. I'm expecting good things.

Great Post! Very informative there.
Simply justified my DDDAC direction where I spent a small fortune to further enhance the design to a more analog/vinyl alike experience. If my ears and mind weren't playing tricks, I think I have found it!

For those haven't heard one, you must have a practical listening experience in order to believe, this kind of thing is very difficult to convey without practical listenning experience.

For those are looking into acquire one, highly recommending you to wait for DSD from Doede. I think he is about to come out a more update technology, DSD DAC is on the horizon.

Best,
Chanh
