Product Description
A great pairing for laptops and smartphones, the Topping NX4 DSD is a compact DAC/amp loaded with impressive specs. It’s equipped with the well-regarded Sabre ES9038Q2 DAC, along with an XU208 USB bridge, and it supports some of the highest-resolution audio—including 32 bit/768 kHz, DSD256 (DoP), and DSD512 (native) Read More
It's a pretty good portable amplifier, and it has enough power to drive most headphones.
But now there are some alternatives, so I recommend you to choose carefully.
like nx7, g5, etc.
Great Dac that provides great audio for the price, but for some reason when I got mine the box was damaged like a big slash mark on the face of the product box, but everything else was in order. It was just odd
I love the sound and for. Factor of this but having sepperate plugs for charging and usage is jank at best. Especially when a single USB c could have done a better job over all
... Have I ever actually used this outside of testing?
There's actually a bit of a story behind this one because I didn't purchase it directly.
Long ago I had purchased the NX2S which was pretty much my go-to when I was working off of a laptop. At some point though, I lost the NX2S. In the midst of my caterwauling and whining an offer was made to replace it.
I jokingly tossed a link to the NX4 here on Drop.
Then the money needed to buy this... arrived in Paypal.
Well, okay then.
A little while AFTER getting the NX4 in, I set-up to go out for a drone-flight, and which point I found the NX2S. In my drink cooler bag. In the food freezer. Where it had been for at least 5 or 6 months.
The NX2S, after it thawed out, still worked flawlessly. Major points to Topping for making a product that could survive being food frozen.
Sadly, the tale of how I got the NX4 through the courtesy and kindness of a stranger who probably just wanted me to shut up about my missing NX2S, is all I really have to say on the product itself.
I had really moved away from carrying wired headphones with me as Anker's Soundcore Vortex cans delivered an acceptable music quality over Bluetooth, and a Zorloo ZuperDAC-S had arrived literally day after the the NX4. (Despite having been ordered like a month before when I couldn't find the NX2S). So for most of the cases where I might run out of battery or be playing a game where wired performance might be preferable, I wound up using the Zorloo.
For all the NX4's bragging rights in audio processing, it's massive battery, it's superior physical inputs over the NX2S, I can't think of a time that I actually, personally, used it.
Despite that, it's the DAC/Amp that sits in the same bag with my Velodyne Aluminum reference cans. I think, maybe, if there were a version that didn't have separate USB input and USB charging ports, and just did everything over a single Type C... I'd happily plunk that cash down today.
So, why would I recommend this to a friend, if it's not quite the product that I'd want to buy? Well, partially it's because I accidentally stress tested the build quality of it's older cousin. That's a huge selling point for somebody who wants a reliable product that can take incidental abuse. It's also because I like the tactile feedback of the physical controls. I can't claim that this was the best priced DAC/Amp, or the best performing of it's class, or any other high accolade. I can claim that it's one I do trust to work when I need it to.
This was an upgrade from the FiiO Kunlun-E18 for me. I was keen to get this after the fella at Audio Science Measurements gave this a high review as the best-performing portable DAC-amp. I can hear the improvement. I have used these mostly with the Etymotic Research ER4XR headphones, and occasionally with the Beyerdynamic DT880's (250ohm). With the Etys I can hear the low noise floor disappear into nothing. Dynamics have improved, and build and fit and finish is excellent.
My only wish is that they integrated a Bluetooth receiver into this, but I'll take better performance over BT.
chose this over other options in this range because it can be used as just an amp. i didn’t want to override the dac in my dap, but i still like the idea of having the option; which is why i didn’t just get a straight headphone amp/boost device.
this is my first portable dac/amp, so i have no performance comps, but for what it claims to do, combined with the asking price, i couldn’t be more satisfied with my purchase.
using with cowon p2 mkii, meze 99 noir & classics, sennheiser 6xx, and hifiman 400i (old) & 4xx; all get a little something extra from the nx4. most notable however, is the hifimans finally get the ass end they need to be a damn near perfect headphone in the $200+/- headphone range...in my opinion, of course.
Provided USB-C to Micro-USB (yes, this product still has Micro-USB) is of a garbage quality, the cable had to be perfectly flat otherwise it wouldn't work. Had to find a replacement cable, everything works fine now.
As already stated, dated Micro-USB
Positive things:
Great and balanced sound, although i would read reviews for that somewhere else than at Drop :)
Velco mounting for you phone and the DAC.
