You wouldn't know what that "something from TEAC" was would you? I am very interested in the TEAC NT-505 as a two-in-one solution for a music file/online streamer/DAC solution for my bedroom audio setup. I have the Topping DX3 and like it very much, but right now it is just being used as a very good quality DAC to feed powered stand-alone PC speakers and headphones at my computer desk. I would be a tad-bit surprised to find-out that the DX3 outperforms the much higher-priced and [so far] relatively well-reviewed TEAC NT-505. But, I guess that's what we find out in this forum all too often, isn't it?

I dunno, really, their NT/UD look the same. It most likely was one of AK4497 models. I honestly couldn't feel even a subtle difference and though I am always sceptical about these things(it could possibly dim my real feelings), they sure had their fair shot. IMO, expensive sources have overloaded circuitry which solves nonexistent problems and/or does same things differently for sake of marketing and justification of higher price. But if you really need higher frequency range, two TEAC-HLCD, TEAC-QVCS, OSRD RDOT-NEO upsampling, Bulk Pet usd, dual mono with separate transformers, whatever practical use all of this has, some expensive certifications for compatibility with very specific hardware/software - then go ahead :)

Mine is 1902 so it seems not to be a general rule. But maybe I've got new remote and power supply because of replacement of my faulty DX3 Pro by Topping.
Yeah, it might be because of refurb. On russian forum 4pda another guy has new 1904594xxx unit, which he ordered from china in late may, with glass screen, new PSU and RC, while 1904593xxx still has classic package.
I would also like to look inside my unit to see if my dx3 have AD8620 installed, but can't find how to disconnect board from the screen and volume control, front panel has no screws. However you captured your chip, I had no success.

My unit doesn't seem to be refurbished. I couldn't find any evidence it was refurbished. Foil on LCD, everything packed like brand new. Topping also didn't tell me they're going to send refurbished unit. Either they did it perfectly or there was no fixed point in production for which they changed power supply/remote.

Received my unit 5 days ago, batch 1904. Replaced my fx-audio dac-x6, very impressed with the quality and sound, amp drives my dt880 250 Ohms no issues at all, volume knob very precise and linear like digital on windows. BT works perfect, remote also with 2AAA betteries which is good. Nice display and overall solid build.
Could you please reveal first 7 digits of your serial number? Did you get new or old type of power supply? I'm courious if your SN fits the pattern @MPeaches mentioned.

update.
The package arrived in Italy without requiring the payment of customs costs. I rejected the package and the seller SHENZEN AUDIO immediately refunded me.
I'm really happy. I also highly recommend this seller
Great news about no customs fees and seller.
May I ask why did you refuse delivery and ask for refund if there were no additional costs to you?

I like the all in one package of the DX3 versus the JDS Atom + separate DAC, plus all the criticism the JDS gets for below par build quality but the reliability issues I am hearing about the DX3 Pro sound pretty scary.

I am thinking I should just get the Atom and a seperate DAC; it may not be as pretty and feel a bit cheap but we know the performance will be top notch and it won't fail on me. Does anyone know if JDS is coming out with DAC/AMP combo version of the Atom soon or should I just get seperates now OR are we confident the DX3 Pro quality issues have been corrected?

I'll be driving HD650's.
For me having the cheaper case on the Atom vs potential issues on the DX3 pro.. no brainer to go with the Atom and separate DAC (Tone Board). We are calling it the ASR special! :)

I started to keep a record of the unit going into standby by itself. Here's what I have so far.

4/16 - 12am
4/28 - 3:44am
5/8 - 10:11pm
5/20 - 3:22am

I wonder if it's a pattern? Seems to be happening fairly consistently every 10-12 days.
Mine always goes into standby by itself if it's not in use. I figured its a power setting and useful feature. It never goes off while in use though.

I got a new one with serial 190... but it has the problem with clicking when I stop music and start again while connected over Bluetooth. Is it normal? No KHz changing.

Start Music - Click - Stop Music - Click
Youtube: Only changed the time of a music - Click!
Mine clicks whenever I change inputs e.g. from USB to Optical or Bluetooth. I figured this is a feature of the device, not a fault or problem.

I also have a 190 serial number unit :)

Just an update for my previous post ( https://www.audiosciencereview.com/...dx3pro-dac-and-headphone-amp.4967/post-173391), as promised:
Ordered DX3 Pro from Amazon.de From tracking info found out it was shipped from China, but when ordering via mobile Amazon app it wasn't apparrent that it would ship from China, but it said German VAT already applied and included in price.
Due to shipping from China there was possibility of significant additional cost to me, VAT, customs/import/handling fees. Croatian customs office indeed applied all of these fees to the parcel prior to delivery.
I've sent a message to seller Shenzen Audio via Amazon.de about it, and they issued a refund for all these additional costs. We exchanged few messages, they were very polite and forthcoming all the time, and replied quickly to every message in a most satisfactory way. So thumbs up for Shenzen Audio seller from me and huge recommendation. I don't think I have ever had potential nightmare online shopping turn out into the most pleasing shopping experience that smooth.

I haven't had much time to test DX3 Pro, but in these few hours I really really love it. I came from onboard audio, and later Creative SB X-FI HD external, also tried NuForce uDAC3 for a few days (wasn't satisfied). DX3 Pro is worlds away. The sound is much cleaner, much more powerful. I can hear more details, for the first time it's not muddled and I am beginning to understand now what all the talk about soundstage and separation is. Now I need to save some money for more decent headphones :D
My serial starts with 1904, and remote that came with it uses 2 AAA baterries.
I'm using a pair of Sennheiser HD 650 headphones with my DX3 Pro, and I can tell you its an amazing combination :D

Hello guys I am in the market for a headphone amp/dac all in one combo.

I have narrowed down to the Topping D3x Pro, Aune 1xs and Xduoo TA 10. Despite the questionable quality of the topping, I am kinda leaning towards it as it is able to run less sensitive IEM with no issue. I will be using the amp with HD660S.

Any opinions on that? All 3 of them will be rougly on the same price point with the topping being the cheapest and Xduoo the more expensive out of the bunch

hello, European friend, :p:)thank you!

The Dx3 Pro is also sold by amazon.it. So I bought the Dx3 Pro on amazon.it.
With amazon.it I have the possibility to make returns without paying shipping costs.
After trying the Topping D10 / Jds Labs Atom combo I decided to return the Dx3 Pro to amazon.it

Now then I own D10 / Atom and I'm happy. After trying them both I preferred D10 / Atom

Ah, I understand now.
Sounds like a nice combination. Hope you enjoy it!

This thread is much too long and winding. It might be a good idea to put mods in a separate thread from the review. As for the initial version having problems, this even happens with expensive stuff as anyone who bought a Nikon D800 early in the game learned.

on sale for 3 more days: https://www.shenzhenaudio.com/toppi...bluetooth-dac-headphone-amplifier-dsd512.html I found the link with a duck duck go search for Topping DX3 pro. It's hidden otherwise.

You can also buy the dx3 pro from aoshida, with the code FANS, for $180 :)
Oh, by the way, I love my dx3 pro. Using it with a pair of jbl lsr 305 mkII and with a beyerdinamic dt 770 :D

Well, for a $7 savings that's fine, but I already ordered. I will use it with HD6xx. Mostly, I listen to speakers, but the DX3 pro will fit on my night table. I listen to headphones in bed when I am too wiped out to sit up in front of my LS50's, or when we have guests.

Oh, the seller on Amazon.de just increased the price. I always have problem with Bluetooth Module when I buy a BT5.0 Receiver. There are many short disconnection or jump in the music. But the DX3Pro is the only without any problem even APT-X.
Does anyone have a idea why? Is there a "cheaper" Bluetooth Receiver which should be ok?

If the source of bluetooth stream is smatphone with Android, the reason is the effort of android to save battery. Newer Android has this saving hidden in the battery settings - every manufacturer on its own. As soon as I turned off the display, the smooth flow of sound started to stutter (I even streamed .dsf files via UAPP and no problem) My older but still vital Samsung Galaxy S6 only has a factory-approved SBC codec. But through the Magisk module for AptX, the AptX HD also has these features (installed LineageOS 15.1). The system automatically selects the highest available codec when pairing. Great for
DX3 Pro !! Only this energy saving for bluetooth needs to appear in the settings. Of course, root, Magisk, and AptX modules are mandatory
