The Taboo MKIII would be my amp of choice with the HD800, you do not loose the detailed presentation or giant sound stage (actually you can make it bigger with the lucid modes) BUT you gain a little warmth, just enough to take the edge off the top end... delicious, detailed and faptastic sound!
See it: I have no interest in a hype. why? I have nothing of it. Again, let it surprise you. You will understand what means perfect balance.
WTF bro!? you aren't even on the hype train, you're the damn conductor!
One gets the impression:
If they tell people a good thing today, now comes the knife.
Maybe people want to hear rather bad things, or:
Yes, the K812 is a headphone of a thousand headphones.
very nice and informative.
And if one says: Finally a headphone with perfect balance, get 100 knife.
Say, much better than HD800, immediately come 1000 knife.
Maybe this is normal today. people want to hear bad things.
