Thanks. Valuable feedback. I did check these things. I can’t get a peep out of any DAC connected directly to it. If you look at the specs, input sensitivity is 0.25v which is very low.
The JDS Labs Atom has a line out which is volume controlled. On high gain, playing classical music, volume on the Atom set to 50%, the Yaqin plays loud enough at about 75% volume. There’s no discernible clipping/distortion till the Atom hits 90%. Even then, it is negligible. The Atom is a poster boy for neutra sound. As a result, the Yaqin sounds clinical, precise but rather limp. No tubey warmth. Playing from Amarra helps since this music player, by itself, has a warmish character.
I had an old forgotten FiiO K10 USB DAC -amp, predecessor to the E10K. It has a line-out independent of the volume pot. Fished out, dusted off and plugged in, it sounds heavenly! Great detail and loud enough.
The line out from the Dark Voice is fantastic too, but expectedly very, very warm.
Anyway, I’m enjoying playing it off the E10 for now.
