Oh dang, that I didnāt know. Now I really canāt blind buy it
Thatās what Iām expecting too, but I wonder if it will be too sterile with the edition XS(or heck even just the HE 4xx)
Yeah, Amirm on ASR measured a huge drop off in scaling below 32 ohms where at 12 ohms it clipped at below 2vrms(which coverts to maybe 200ish mv?)
So that was a little weird, though pushing that much power to low impedance high sensitivity IEMs doesnāt really make sense so I thought it would be a non issue.
Btw which IEMs did you try it on and did any synergize well with it?

I know Iāve talked about it a lot on these forums but I actually donāt hate analytical sound, it just isnāt what I prefer most of the time. I still have an a90 and use it on occasion and itās a great amp. I think the dx3 would still do just fine with the XS as the XS has some character to it all on its own. On top of that, even with my burson amp I still use a gustard x16 DAC which is one of those measurement queen DACs and I love it. Itās a detail monster and with a bit of class a color plugged into some nice resolving planars it leaves me wanting nothing to be honest.
They all sounded fine. At least Dunu Zen and 7 Hertz Timeless. But, I listened only for a few hours before I put it back in the box. I didnāt buy something to effectively have less power than my Qudelix. It was ridiculously underpowered. I was looking for an inexpensive power equivalent to the ifi micro signature. It was not that.
Interesting, I was worried it might be too much. So with the zen and the timeless you have it turned all the way up and it doesnāt sound enough/sounds like it lacks something other than volume?
I was looking for an inexpensive step up to the ifi Zen dac which recalling by memory is just marginally beaten by the old model of their micro line, I havenāt heard the signature yet though. Guess the DX3 Pro+ isnāt gonna beat the zen in power and sound?
Same thoughts. I donāt really keep multiple amps but I tend to go for the slightly warm ones. So Iām curious(and cautious) on how dramatic would analytical sounding amps push some gear towards a colder sound.
I didnāt analyze it. Let me compare to the micro signature. On eco mode, the dunu Zen iem feel like you could make them destroy your ears in an effortlessly loud way. On the dx3, it felt like it was working to make it go when at damn near max volume for something that is supposed to be high watts. I basically lost confidence in the unit. It maintained control, and sounded fine, I simply didnāt believe topping delivered what they claimed.
Not with IEMs. I canāt speak to the bigger headphones. But my experience with the a90/d90 was kind of a scaled up version of this. It never really impressed outside of the drop dead neutrality/transparency. Which, for me, doesnāt come off as a benefit.
Knowing what I know today, I wish I kept the micro signature. The xdsd gryphon is in my sites now.
Perfect explanation 
I understand now, thanks. I wonder if putting on an impedance adapter on the plug will solve this since it seems perfectly capable of driving a watt through 32 ohms or higher 
Same here! Iām itchinā for an upgrade too and this looks to be the contender to beat when it comes out!

I would think so. I would have tried iematch if I had the right adaptor. But it still wasnāt going to be kept.
In case it matters:
2 Vrms ā 2.8 Vp ā 5.6 Vp-p
Does anyone use this topping with some low Z IEMs after all this precautions? It is so tempting piece of equipment to have right now, but I am 50/50 headphone/IEM user so I donāt know whether that would not destroy the whole purpose of one-in-all equipmentā¦
I just recieved the DX3 Pro+ today and after the first 2 hours of listening via bluetooth, Iām loving it. This replaces my Ifi xDSD whose battery would no longer hold a charge (and then I buggered it beyond repair). That being said, I no longer miss the xdsd.
Lowest impedance iems used so far are 7Hz Timeless. 14.8 ohm, 104 db. Itās crazy loud for me at -20 in low gain. -25 would be loud for me, but -31-27 is a better level for normal listening. Based on comparable levels on Q5k, I suspect -20 is still below 500 mv, and so nowhere close to a level that would clip.
The two most difficult things I have to drive are the Koss DJ100 (38 ohms, 99db) for headphones and Shuoer Tape (?) for iems.
Short test period, but went through the following (all BT and none needed high gain):
7Hz Timeless
HBB Olina
HBB Mele
AKG K371
Koss DJ100

Joined the Topping DX3 Pro+ crew after a 10% off sale hooked me in. I was after a DAC that would go with my desk setup (for headphones and Class D Speaker Amp) but could switch out somewhere else if needed. I like that there are seven PCM filter options even though the default F-3 Fast Roll Off is pretty much the compromise between them but I might spend some time with F-2 (Fast Roll Off Corrected Minimum) and F-5 (Fast Roll Off Minimum) as well. Installing the drivers was a bit weird because I had to run it once, reboot, and run it again to complete the installation (reading is important). Also updated to the latest firmware. Plenty of power for IEMs.
I need to figure out if I can get the ASIO working, but so far havenāt noticed any issues before or after installing the Topping drivers. Sounds like it should and all the LEDs appear to work.
Eyeing up some better RCA cables (like it matters for the short distance to the speaker AMP).
On my dx3 v2 (non +), i sometimes lose sound on Windows after having listened to foobar in asio mode. It seems there is a bug in exclusivity releasing or somethingā¦ I then have to reboot the topping (unplug and replug) for it to work again .
Iām not sure where the default comes from (foobar, drivers, the unit,ā¦)
And here I thought my biggest problem would be having to hit the output selection button.
Iāll have to test this bug once I figure out ASIO. I love that the Topping drivers let you set the buffer size (for ASIO) along with having a good default buffer size.
Maybe you wonāt have any problem, i donāt know.
I personnaly am not really happy with my dx3 pro V2:
- the volume change is too slow
- the feeling of the knob bothers me (I much preferred the smoothness of the ifi zen)
- it has a really high output impedance (specific to my model)
- the volume output is generally way lower than what is announced: I have to put it on -30 ~-20 to get proper volume with my hd6xx and he400i

Yeah, it is more of a DAC that happens to include a Headphone AMP.
The Knob on the plus is a little better than previous models, but the back and forth of the volume control can still drop a number. I am sure a lot of work went into matching the ādigitalā knob tic to the digital volume change, but I agree, smoothness on knobs is just better: give me a knob with some heft and resistance that I can spin without making my nerves feel funny. I didnāt really consider much about the user experience and feel for the DX3 Pro. I was after value for specs.
ASR measured the max power output on high gain at 32 Ohm is 1.5 W for the plus, which is 500 mW more than the V1.
Yeah I know: the numbers of the topping are way higher than the zen dac. But what I remember is that the knob was at 12 oāclock for my he400i. On the dx3 pro itās at a level that would correspond to 16 oāclock.

Is it me, or is there a marked difference listening to the DX3 pro+ through bluetooth vs USB?
I had only been gaming on it until last night when I loaded spotify onto my pc and there seemed to be quite a difference.
