Agree. From plots, it is clear that DAC2 has flatter frequency response, and DA8 has a drop at high frequencies starting from 10kHz, and reaches ~ -0.2db at 22kHz. That's a lot. This might be the reason for many people mentioning DA8 being more listenable, and DAC2 being bright. For this reason I will go with DAC2, because I never feel DAC1 being bright.
But at people also mentioning DA8's sound stage is more realistic, more layered lows. It's a tough call.
Can you really hear a 0.2dB change in 20k?
You must have a set of outstanding ears, if you do.
