All the good tube amps (EC, DNA etc) are US based so also a matter of support, tax etc.
One of them is retiring unfortunately. You could get one of the last EC amps until they close shop. They offer special goodbye deals but most of the stuff is gone already @Empyah (german based or based German?) got an EC Studio Jr and he's either going for the V5XX or US4+ for his SS love.
Where are you located?
V281 has reached EOL so a dacless version is naturally inevitable. Expecting October or November.
Which DAC are you using right now?
I am actually either portables or speakers person, and never really considered going for a stationary headphone setup until now. But now entering the planar era with D8000 Pro, decided to go for one. So my HPs are D8000 Pro, Denon D9200 and occasionally HD800 (normally used by my wife for studio work). Just to give an idea: I find the Utopia too mid forward and upper mid aggressive in general. For speakers I have a HEDD Tower Mains + oppo 205 setup and I am very satisfied with it - so the oppo 205 serves as a DAC at the moment. I might get a dedicated DAC in the future but that is for later (also my two portables Hiby R8 and DX220MAX).
I don't want to be collecting and buying/selling equipment in this price range too often, so wanted to get something that I will be satisfied with for a long time. As speakers, I am always inclined to studio monitors with dead neutral signature (though both D9200 with its U signature and D8000 Pro might be a bit on the fun side of the spectrum).
I am located in Berlin / Germany.
