Hi Henrik,
i have two Hifiberry Dac+ Pro and without hacking the Board
=> splitting the power between Hifiberry and Raspi I was not satisfied.
After splitting I added a Batterypack to power both the Raspi and the Hifiberry and not poison anything with a bad psu.
From that point on I was really satisfied with the setup.
But as always better is the foe from good and I bought for my third Raspi an Allo BOSS DAC after reading some very enthusiastic reviews. And this setup satisfied me from the start.
Just warmer and a little more punch in the low area.
I also tried an Ifi micro IDSD for headphone purposes and that was a little too much for the Raspberries as the USB is not very clean and there was ticking while playing hires-files.
For this setup I use now Daphile with LMS on an old netbook and this worked better.
=> but no Roon Implementation
On my working place at home I installed the Roon Software (Windows 10) and play via Asio to my Sanskrit Pro DAC with the Panda Setup (headphone amplifier + DC Voltage from Sanskrit) A very nice setup without hickups and perfect DSD implementation and perfect sound to my ears. Maybe it’s also due to the totally oversized iCore 7 Quadcore in this laptop from Acer. And I hear the music with my Beyerdynamic headphones.
The different players are working in different zones on different stereo setups.
Allo Boss Dac+Raspi attached to an old DSP A1000 Yamaha with open baffle self made FAST System (15 Inch bass Visaton + B200 Fullrange Visaton) in stereo mode. My favorite when it’s about enjoying music and alone at home
Hifi Berry Dac+ Pro + Raspi in my “studio” (private motorcycle workshop) with a tripath “no name” amplifier connected via Wifi and as output some selfmade Fullrange Speakers with a transmissionline and for the low end a 15 Inch bass as open baffle subwoofer with a reckhorn amplifier.
There I use the DSP program from Roon to lower the subsonic with a filter. Because the transmissionline fullrange speakers are only 3,5 inch big ;-)!
So you see you can make a lot with these different setups and I was looking for a long time for such a nice and working solution as Roon represents for me! Thanks to Hans Beekhuizen and his missionary work, maybe he didn’t intend to do so with his Roon reviews
My Roonserver (core) is running on debian 8 and the files are stored on a synology ds216j with a 1Gbit connection.
I’m still surprised with the performance in Roon with my 3 Terrabytes of music. Even over wifi to my workshop changing music or track is without any lagging. Never had this with LMS Implementation (Logitech Media Server running on NAS or even on a dedicated PC for that purpose.
So for a starter with all my experience now => I would buy a raspberry PI3 + Allo BOSS Dac install dietpi and the Roon Bridge and hook this up to the stereo or headphone amplifier of your choice.
And just like Hans Beekhuizen alwas says on his Youtube Channel “And whatever you do enjoy the music”
Cheers
