I want to build my first HI-FI setup, it is for a small room (about 12m2) and I need help to choose an amp+dac to power up a pair of Dali Zensor 1 speakers and also K612 or DT880/DT990 headphones.
 
It will be used for playing varied style music in FLAC, ALAC, DSD and etc. formats feeded through net, a mac mini, and also is important for me, gaming with a PS4.
 
My budget is max 300-350 Eur.
 
I also have a Mixamp Pro 2014 to add the setup, if that get sense or helps anyone to give me advise. 

Best to look at audio/video receivers or stereo receivers with a DAC if you want something to hook your speakers and headphones to.

Since the 612 is unlike the 7XX I would recommend a OTL amp with a pre-amp (If you have powered speakers) , 612 is high impedance so are Beyers so you'll get the tube voltage and decent damping too , to get the best authority on the driver 
 
DSD in that budget , why ? .....High-Res should be enough

You might consider getting a Yamaha A/V receiver, it comes with Silent Cinema, Yamaha own headphone surround sound technology.
You could connect the PS4 and Mac mini to the A/V receiver using HDMI, then HDMI from the receiver to your screen.
The receiver can easy drive the K612 and DT880 headphones, as well as the speakers.
 
As I live in California, I have no idea on where there good deals on receivers (new or used) in Europe.
But try asking on the UK website AVforum.
 
May be able to then sell off the Mix-amp Pro, for cash.
