It certainly can... I've been playing .dsf files today. Sounds spanking.

git a plan for a linear psu for the pi. my aquvox linear needs an adapter to make it fit but should pro ide all the power needed....acually it will neex 2 adaptors but can get them cheap so no great loss if it doesnt work.

Got the 2 adaptors ordered so will let you all know if it works :)

Ok, so after reading this thread I decided it was time to order a pi2 - primarily to replace my hacked ATV1 (crystalbuntu os & HD graphics card replacing wifi adapter) multimedia centre, but thought I'd add an iq-dac+ too. I ordered 2 SD cards, one of OSMC (dedicated os for Kodi multimedia centre), one for Volumio for audio playback. I am not detecting a sound quality difference between Volumio (using dac+) and OSMC (using hdmi audio out), and neither compare to playing the same source via my Naim CDI. Via Volumio & OSMC I'm playing same iTunes ripped 320kbps files - is there a way of ripping to higher quality? And what AlSA settings should I be making to ensure highest quality? Both dac+ and hdmi output sounds good, but soundstage and imaging are poor compared to cd playback.

Thanks, Richard

You can rip to WAV in iTunes...you need to tweak the export settings from preferences and select WAV.

I found the sound stage improved by setting up sampling to 176.4/16 using SOX high quality...

Dunno if its possible to do easily but will try and see if I can connect mine to the laptop upstairs' music files on another hdd via the router. It'll either work first time or I will probably give up. Never been good at networking

Where do I set the up sampling please? And what are the important alsamixer settings? Think I have master volume one notch up, filter and other two volumes as default (0). I also disabled volume control in the Volumio web interface.

The current RB3 of OSMC does not recognize the dac+ natively, so I'll need to go into the Linux OS to set it up. But like I say - I detect no sq difference using Volumio via dac+ and its line outs straight into my pre, and OSMC feeding audio over hdmi into TV and TV line outs into the pre. And while both are acceptable, neither match sq playing the original cd.

I'm hoping I've missed something in setting up the dac+.

Thanks, Richard
