I been interested in f.audio, since I got there s1 but I am very hesitant, does it's still have the 10db sub bass roll off?
Pls. refer to Cqtek's measurement. 20 Hz drop is 5 dB.
But I think a small drop in lowest bass is not that bad. Low frequency distributes more energy than high frequency. If the drop is slight, it helps power distribution and hence headphones driving power.
You have to denote the "empty socket version" upon buying. Also, this version doesn't come with two OPA1612. You have to buy two dual channel op amp separately (or four single channel op amp, conversion boards, pins, and do the soldering by your own. My soldering is not bad, isn't it).
