"Topping nailed it once again and created a fantastic portable companion. It is so good it is probably one of the best sub-$200 portable DAC/amps on the market right now!"Read More
"The NX4DSD uses good parts: an Alps switched potentiometer, a high grade USB decoder chip (XMOS XU208), the very detailed ESS9038Q2M dac chip, and quality opamps (OPA1652, OPA2140, OPA1688)."Read More
As always thx to headphone zone for making these audio brands available here. I had couple of reasons to go with topping NX4, s/n ratio and THD curve, I replaced my older fiio q1 mark 2 with the NX4. The difference is very obvious, top end treble is crisper and good subbass presence. Generally portable Amps filter out subass, but not on NX4, there plenty of bass and no muddiness. As a DAC again good performance with flacs, and good quality MP3 from my phone. Streaming movies sound good with clear audio. But I use it primarily as an amp for my ds160 and there's enough juice to drive all my headphones. Like any good audio product not much to fiddle with, there's a high and lo gain switch to drive different type of headphones. The bass switch adds good thump to lower end and again no muddiness in bass, tight response. So happy customer would recommend to anybody looking for a portable DAC/amp.
Hey Girish, thanks for taking time and sharing this detailed feedback, we really appreciate it! :)
Has plenty of power with extremely fun sound signature. Turned my HD 598 SE into bass heavy cans. This is slightly bright in tone. Only con is mids are slightly recessed. But overall very good value for money. I liked this better than Schiit Magni + Modi combo.
