Amazing First Contact With a DAC/Amp
Been using the Topping DX3 Pro everyday for roughly a month and couldn't be more satisfied!
I was a little afraid at first, because of the defective units on the older version, but it seems that issue was resolved on V2.
It's worth noting that they've changed the output impedance from <1 ohm to <10 ohms, so maybe it can affect low-impedance IEMs.
Personally, I couldn't tell any problems when driving my Sennheiser HD 558 or my newly acquired HD 6XX.
Well, gotta say I'm positively impressed by it. When first pairing it with the HD 558, the difference in sound quality became clear — the amplification gave a new breath of life to these 5-year-old cans.
No distortion noticed at all, even at higher volumes. The details were sharpened. Bass also got punchier. Vocals seemed more upfront, but not to the point of obscuring any other frequencies.
The DX3 Pro also packs a punch. Its default volume setting is at -30 dB and I rarely go beyond -20 dB. At 0 db, you get yourself a new pair of speakers…
No formed opinion yet when it comes to driving the HD 6XX, since I just got these headphones a couple of days ago. What I can say is that it looks like this DAC/Amp provides enough juice to extract most — if not all — of the HD 6XX.
Regarding build quality, this thing is pretty solid. It also have a nice finish and looks great, pretty sober.
The display is well lit (you can adjust from 3 steps) and functional. The volume knob is really responsive and quite pleasant to use.
Usability is pretty straight and simple on this one. You take the equipment out of the box, plug the USB cable, plug the power supply and that's it. Ready to use.
Inside the box, you get an atenna that makes the DX3 Pro work via bluetooth, which can come in handy.
It also comes with a remote control, making it practical to change between outputs or just adjust the volume from afar.
Overall, the Topping DX3 Pro is an amazing all-in-one solution, especially at this price point ($180).
Would recommend to a friend.
