Headphone out via HD650 and RHA MA750i
The headphone out will sound thin and digital, it doesnt have the strength to push the bass and subs out effectively, heck even on my IEM it needs at least 2 o'clock of volume turned, and even more on HD650. Kind of expecting to be disappointed if to use Q192 as the headphone out. Everything feels dead flat and there is no enjoyment to it like listening to your stock IEM from the phone bundle. Urgh~
Digital out to Alesis Elevate 5 speakers
Since my speakers have their own amplification, RCA out digitally would be a better option, and still, bass couldn't be punched out effectively, but the mid vocals and high notes are very well portrayed out. Clicks and beats can be heard clearly, although micro details could be buried at times. Some passive speakers could use this, as there is the option to switch between fixed line out or variable line out, and when I tried out the variable line out, just for fun, turning the knob up to 3 o clock, again..
In comparison with the UD120, the Q192 is cleaner and has better power. Bass performance on the Q192 is better than the UD120. Q192 totally wrecks the UD120 in every perspective.
Well, this one is a bit of a swing, Mojo has better power but by a close margin with Q192, but considering that Mojo is battery powered and small, it will be an issue when the battery runs out and you will have to recharge it. Q192 wise, if you have a micro desk space, this could be a "where do i put this?" problem. Sound wise, both can be recommended, although theoretically Mojo is intended for IEM.
Fiio X5ii as DAC out
Fiio X5ii DAC stand closer to the UD120 than to the monsters. Volume gain isnt much so you have to turn up the speaker volume to get decent sound quality, but factor in it's lightweight and has power passthrough once full charged, suitable for micro desks.
