The next new dac

[Gordon Macfarlane]

Hi guys , as posted previously I want to try building a tiny music server with built in dac.

The computer is a Raspberry pi running Raspberry-fi (still a work in progress due to having to learn Linux command line stuff)[not in picture]

The dac is USB input via the Amanero USB-I2S board and the dac is Sabre 9023 based.

Still waiting for the power supply for the boards so in the meantime I am using an Analogmetric linear psu which will eventually power the Rasp.

Tommorow will be the first test run but I thought you might like to see a pic of the 'breadboarded' system.

Wow!

 

It's an actual bread board

 

looks like fun, mate

Hi Ian ,got the main system sounding very good so now playing around with stuff like this , mostly for fun but also hoping it will outperform the Win8 based music server.

Must get round to having the LP12'S warped plinth sorted so I can  start listening to my Lp s again.

[Guest Muon]

Certainly would be nice if it can replace the PC.

 

Warped plinth? so does that mean a new plinth for the LP12, or is it going to be a repair job?

Great stuff !!

Now thats a  bread and butter budget

Still trying to get the Raspberryfi OS to see my hd with all the music on it. :mad:

USB? Don't know the commands or something else..

 

this page may help (different OS but commands are somewhat the same)..

Any other issues you can start a shell, and run "dmesg |tail -n 20" and hopefully it'd tell you of the errors. 

 

For mine I put the music on a NAS, mount it using NFS, so that I can keep the USB port free for the DAC (Never got to get hi res streaming to work though and it's now running raspbmc for video watching )...

My little R-Pi music server has been running like a champ as well.. I'm just using a USB soundcard though, and also have my music collection accessible via NFS.

It's alive , making music and sounding great on headphones. The Ipad app MPAD is still not working but am able to control the server via Gnome music player client on my desktop pc. Now to order the high quality power supply for the usb and dac boards, find a good looking case to put it in and make some short usb cables so the inside of the box doesn't end up looking like a rat's nest.

Hi Myrantz , thanks for the tips.

I had my usb hd formatted in ntfs , followed all the instructions to get this working but no joy. Reformatted the drive in FAT32 and now I am getting music

There is a usb audio fix over on Raspberryfi which allows bit perfect output and some of the guys have this working at 24/192 : http://www.raspyfi.com/raspberry-pi-usb-audio-fix/

Hi guys , forgot to update the thread.

Had the Pi server up and running for a while now : sound ,as background is great but was thinking probably not ready as a principle source. Played a track from a Manhattan Transfer album I like and was rather gobsmaked by the quality. Wondered it it might be one of the hi-res files I have but according to Mpad it's just standard Flac.

So it may well be worth the expenditure for better psu's and usb isolation.

Will report back when I have made the changes but it may be a while as I have other projects to complete.

I'm still waiting on my final bits, but I'm doing similar with Raspbyfi, ES9023 24/192 dac and an Xmos based 384kHz to I2S converter. I'm a bit of a convert to Linux as a side issue because of this project, my main laptop now running Ubuntu 13.10 and it literally flies compared to windows 8.1.

 

There are some issues getting the Pi to mount my Nas drive (Readynas) but I like the functionality - especially the ability to airplay tracks, that will be a winner with my teenage daughters who don't use the SBT because "it only plays your music Dad". I've setup power supplies, LT1085 for the Pi and SuperTeddyReg for the Xmos and DAC.

 

It's a lot of fun, and I'm potentially looking to build airplay right into one of my integrateds using just Pi driving an ES9023 DAC directly from the I2S headers, but need to research the clocks/oscillator implementation for this to see if it's easier/better sounding than via USB through the Xmos converter. The cost is not too bad, 35 for PI, about 100 for the dac/usb reclocker and a little more for PSU's.

 

Ultimately as I've possibly mentioned on another thread, I think awesome results could be obtained using the Buffalo DACIIISE. An easy solution for someone that doesn't have the DIY appetite is Raspberry PI running Rasbyfi into a Shiit Modi from the USB. Simple, functional and with a little bit of geek chick. Thanks for the heads-up on this one.
