Reply to comment by blorg in Really enjoying my new $350 "budget" setup. HD660S and Topping DX1 by Jfox8

I have 250 Ohms Beyer DT 990 and they comfortably run even on my Plenue D2

I mean, there must be a lot even more demanding headphones out there, but most desktop amps also deliver a lot more power...

The Topping DX1 is more like a "super dongle" than a desktop amp, it's USB powered and has power output similar to higher powered dongles.

>280mW X 2 @32Ω THD+N<0.1 %
>190mW X 2 @64Ω THD+N<0.1 %
>51mW X 2 @300Ω THD+N<0.1 %

The Fiio K7 entry level desktop amp (to take an example), does a bit over 10 times the power of this, out of its balanced. You may not need this, but it's a lot more.

I know, my desktop amp puts out 300mW @ 300 Ohm

whereas the Plenue D2 is somewhere around 10mW

yet, those are enough to go TOO loud on my 250Ohms Beyerdynamic DT 990
