Topping DX3 Pro+ Review (DAC & Headphone Amp)

[Kaval]

Does this model offer opamp rollover facility?

Even if it does, I'm sure it's ill-advised. Pretty certain @JohnYang1997 had warned us against it before

 

[Kaval]

May I know the reasons why it's ill-advised?

Hmm... I might go for this one (as I sold my D50s) and mod it with 6.3mm (aka 1/4") headphone jack.

Still... a PCB photo would be great.

I have Sundara's right now and I'm thinking of buying the A50s+D50s. Would the DX3 Pro+ be a better option?

If not better certainly not worse but cheaper. Don't know how Sundaras sound with DX3 Pro+, probably the same as with D50s+A50s, but I assure you they sound soooo nice on the D50s+A50s (balanced) so I got another stack for my other room and declared the end game.

I have dx3pro which keeps shutting itself off once or sometimes twice a month.
Would dx3pro + be a worthy upgrade? Looks like it has 20bits instead of 16bits of clarity.
I basically only listen via speakers connected to RCA.
Thanks

I don't know if this has anything to do with your situation but when I was swapping amps and speakers back and forth a lot my DX3-Pro used to lock up every now and then - presumably upset by some spikes generated by plugging and unplugging other stuff. Since I've stopped messing around with my other components, the DX3 has been rock solid.

I'm waiting for a DX3-Pro+ to arrive to replace the DX3-Pro and also listen mostly via speakers. When it gets here I am pretty certain that I will be totally unable to hear any difference with the only upgrade being that I will then be sure that it's all I'll ever need... plus I'll have a spare and the new one is going to be black which will match the amp better.

Because, in best case it does absolutely nothing audible (other that stimulating expectation bias and causing placebo effects), and in worst case it makes the circuit oscillate or do other horrible things. You have no way of knowing without verifying it with proper measurement gear.

Op-amp rolling is a marketing gimmick, designed to satisfy the lust for crapshoot tinkering. Nothing more.

Hello, although it is the first time I write, I read decades ago about audio, I love the point of view of this forum (I am a psychiatrist so the objective, science, the subjective is always in discussion), I am going to buy this dac/amp, has everything I want to start with (I listen years ago on a nad325bee and cd p + psb speakers), my question is the following, what would be the best way to use it:
1 with an ifi filter since I want to use it with the cell phone and it is USB C.
2 With a dac that has an optical output like the d10s topping (I think).
3 With a rapsberry and allodigione.
4 a USB C to USB A adapter of one unknown brand that in my country is 20 usd.
Thank you very much and congratulations on the forum and on the science.
P.D: English is not my natural language, so sorry for the "horrors" of spelling.
P.D2: im from argentina so everything is expensive.
P.D3: this years im listen a lot o SOFT MACHINE, zappa, charles mingus, ect.
P.D4: got a superluxx 688b, sennheiser cx300, hd202, hd280pro, px100 and i will buy the koss kph30i.

1 with an ifi filter since I want to use it with the cell phone and it is USB C.

No need for galvanic isolation when using a cell phone, since battery powered devices can't cause ground loops. And the DX3 Pro+ will most likely do filtering perfectly fine without the iFi.

4 a USB C to USB A adapter of one unknown brand that in my country is 20 usd.

I would just look for a cable with USB-C in one end and USB-B male in the other?

EDIT: Brain fart! You'll need a USB OTG cable, if you want to use it with an Android phone, and a camera adapter for Apple.

You were right the first time! I've used USB C to B, without OTG adapter, and all works fine to DAC's example. Although, I do use the paid for app USB Audio Player PRO (UAPP) which uses it's own drivers for USB devices. Haven't tried it with other players and Android drivers. app here

[Killingbeans]

does it have to be usb 3.0, 3.1?

5Gb/s vs 10Gb/s, so not a concern. Unless some 1.5MHz/64bit or even crazier nonsense is suddenly introduced, and you want to go down that particular rabbit hole.

does it have to be as short as possible?

No. Not unless your house is an absurd EMI nightmare

 

[ManuMaker]

If someone knows a place to buy it from Germany, please tell me, Amazon tells me that they do not send it there. Greetings!

From what I understand digital cables are quite resistant to emi interference. The only cable interference I have heard VERY audibly was a crappy microphone cable carrying an analogue signal that has yet to be pre-amplified (so the interference was heard after double amplification). Audioblast starquad mic cables which I eventually replaced it with exhibited no such issue regardless of length though, so I daresay for your use case the length would absolutely not matter with regards to interference. It might matter above lengths of 2-3m if your device is drawing power through it due to the effects of resistance, however

I hope it has a sub out. Is it too much to ask for bass crossover management in an integrated amp like this ? There was a thread here at ASR about the lack of such feature in integrated amps.

I'm looking for a Class D with a sub out, optical and RCA in, and a remote. It doesn't need to be incredibly powerful, just enough for some bookshelves, but it needs to be clean and without a high noise floor. Not sure if that's asking for too much, but that's what I need. The SMSL SA300 is awfully close, but it doesn't have optical.

Topping MX3 ticks all of the boxes....

but it needs to be clean and without a high noise floor.

... except that one

Yep, trust me, I've looked. There are bigger (and more expensive) devices that tick those boxes, but nothing in the $150 or less range that have a small footprint.

NX7 still a thing?
