There were reported issues with distortion, clicking, optical input and even clock here. Obviously some if not most of these issues were fixed, and in the foreseeable future the 48 kHz issue will be fixed, but it shows that imo the DX1 II is in its alpha (or beta I guess?) stage due to the firmware bugs.
It is not at all "alpha" for its common application of headphone connected DAC for consumption of ripped CDs or common music streaming. I get that you want to get maximum hype to get the bugs fixed but exaggerating is not going to get you there. It takes credibility away from your argument.

This is a highly capable DAC with features at a price that you can't find elsewhere. If the bugs that it has hit your application, then don't buy it. Otherwise, as I have experienced, it is a superb and affordable device for desktop music listening with headphones.

Many of you asked for advanced features such as PEQ. Well, you now have it, courtesy of a boatload of software in the device. That increases complexity and severely widens the testing surface area. So more bugs get through. As I always say, software is hard! Give the company time and motivation to fix these things or move along and buy something else.
 
...I won't touch another Topping but I am not going to try and convince anyone to get rid of theirs...the Topping device can do that on it's own, or not...
 
A similar product, the Douk Audio K5, is completely problem-free.
That's not remotely the same kind of device in capabilities or I/O. And we don't know if your statement is true without the scrutiny that the Topping is getting.
 
I'm sure it will be fixed in the end but I won't buy anything at release anymore. Enough is enough. As someone mentioned, this isn't a kickstarter company, they should be far above this quality level

Since the CD was invented?

48 kHz is a TV broadcast sampling rate standard. While it is also used for music that is only available from a high-res music service. Even there, it is rare.

By far, the most common application for a desktop DAC is to listen to CD rate music. Everything else is an exception, not the rule. As I said, this must be fixed but the notion that the DX1 II is useless right now is absurd and out of control hyperbole. Just say it can't reliably play youtube video, and some high-res content and you would be OK.
Very strange to see Amir defend a product that is far from delivering on its own technical datasheet and information and marketing from Topping. Cheap or not. Maybe you should have conducted a more thorough test like checking output from RCA. They are there for a reason.

I am not defending a product. I am just annoyed by the hyperbole about the bugs and bringing clarity to what the issues are and their impact. I have repeatedly said the bugs must be fixed. As I said and I repeat, we lose credibility when we exaggerate problems.
 
...it seems like they are still getting earlier devices sorted...
Sure,

Would be truly amazed if they used an entirely different stack for similar products. They are introduced one by one, each having a different feature set, thus it is only reasonable to assume that software features will be developed with focus on one device, then support others in the series. They will likely replace/upgrade more products with these capabilities.

Consequently they or their customers will discover bugs which will affect only one device and remain existent but irrelevant for other products. They will sort out the ones for specific feature sets and pass it down to other devices, and they will sort out the ones which are system wide. But this is very early days for the software, and I believe that should be understood by competent buyers. It means bugs, and it means that the software will become significantly better. They need to be given som slack whilst at it.

As for quality, reliability, featuresets and so on, each must decide if the brand or the device is for them or not. Everyone does that, and righfully so, including yours truly. For me, it ticks off all boxes for my intended purposes, and it's the first dac/amp I've come across doing that. The only bummer is lack of PEQ for optical bypass, which only affects me if I add speakers to my desktop. Thinking it over ever so slightly, it strikes me as a logical choice by Topping given they are actually considering the opt in opt out as a pure buypass. Would assume that is a nice feature for some even if it doesn't suit me.

I'm not worried at all about Topping getting it right and don't consider my purchase a risk at all.
 
That's not remotely the same kind of device in capabilities or I/O. And we don't know if your statement is true without the scrutiny that the Topping is getting.
I own the Douk Audio K5 and Topping DX1 II., so I can compare them. Except for the PEQ and the remote control, they are comparable. Topping has problems with sound popping on the RCA output and hum when shutting down, changing functions and changing the sampling frequency. In addition, it has unpredictable sound distortion. Douk works great, no pop, no hum, no distortion. At the moment, topping is an unfinished device.

Well, you don't seem to know how to compare them. Where are the balanced outputs on K5? And what about the PEQ and remote control? Those are trivial items to be ignored in such a comparison? How about the fact that the DX1 II has a display? That is ignored too? By your definition every DAC is the same as every other when it comes to functionality.

Douk works great, no pop, no hum, no distortion.
Topping had none of those problems for me either. Here is a review on Douk's website for K5:

"Michael Llewellyn

It stopped working
I have it plugged into a PC. It worked at first. It stopped working. I uninstalled and reinstalled the software. It does not work. I have not tried it plugged into my stereo, I need it on the PC"


Should we declare it useless, alpha or whatever based on that?
 
It's already been reported here but I too can confirm that 96Khz has the same problem as 48Khz. About one hour and it goes into distortion

Next I'll try 88.2Khz

If anyone is worried about the distortion, just downgrade the firmware to 15.54.22.54. Until Topping releases a newer firmware, I wouldn't bother with 15.69.22.69. Having said that, if you actually use the optical input, or UAC 1.0, then you might be tempted to stay on the latest firmware, I don't know. If you just use it as a USB device like I do, there doesn't seem to be much point or benefit to the latest firmware anyway.
 
EDIT: I missed the reports of 96 kHz also having issues. So upsampling may not be a workaround anyway, unless there is some higher sample rate that does work without issues.

I can neither agree with nor dispute what's globally common without statistics. However, I do respectfully disagree that complaints are hyperbole, as a buyer or prospective buyer's perspective greatly depends on their intended use. As a potential buyer who chooses not to buy, based on the bug reports, I judge it to be unfit for my intended use and I emphasize my, not anyone else's and hence why I decided not to buy. I use my DAC for gaming, PC and console, PS4/3 and whilst Windows can be worked around by upsampling, consoles AFAICT are fixed at 48 kHz. I also use it for watching Blu Ray and DVDs on Linux and console, which I believe are also 48 kHz, and also streaming video. Again, watching under Linux could be worked around by upsampling, maybe, albeit I've had some weird anomalies with my Linux upsampling experiments that I haven't resolved yet, but can't be worked around for console. Well, actually, PS3 can potentially be worked around with optical but I'm not clear from the bug reports whether the optical input is safe from the bugs or not or just hasn't been tested enough yet. I previously queried this but there were no responses. I actually currently use optical but I was hoping to get rid of some of my optical cables and switch with a new DAC to get rid of clutter. Ideally I just want a single optical cable to cater to the PS3 and everything else can be USB. Out of the around 1000 FLAC music files I have, it's true most are 44.1 kHz but 131 are 48 kHz and 124 are 96 kHz. Unfortunately, my favorite music that I listen to the most fall in the latter two groups. I also would like a DAC to use with PS5, which DX1 II advertised as a feature. Currently I don't have good audio from the PS5 because they got rid of optical from the PS4/3 and only support UAC 1.0.

Basically, for my use case, I judge the DX1 II to be a big downgrade right now rather than an upgrade from my old Audioengine D1 DAC that sure, has far fewer features but performs it's core function of being a DAC without significant issues. If I had bought the DX1 II unaware of the issues, I would have been upset. Luckily I discovered these forums. I've been commenting not to bash Topping but with some hope that they monitor these forums and take the feedback on board to improve their approach in future. If they do, that's great and I will happily show interest in their future products. If they don't, then at most I've wasted a bit of time commenting.

PS. I would also like to say I appreciate the community you've built here. I've found the info on these forums to be of great help, not just with this topic but others as well.

I have just run a 2-hour test on V15.46.22.46 with 48 kHz audio. No issues have occurred just yet. However, I have encountered more bugs:

During standby mode, the device produces a "thump" noise if I accidentally play any audio in Windows.

When exiting standby mode, the device also produces a loud "crack" noise.

V15.54.22.54 has exactly the same standby mode issues. Standby mode is currently broken and unusable. The mute function appears to be working correctly so far.

I haven't tested 48 kHz audio on V15.54.22.54 yet, but I'm lacking the motivation to do so.

This product is terrible.
 
How it's advertised and who will actually buy it is a matter of marketers guessing. I don't play games. Why Windows with EqualizerAPO needs an DAC with an equalizer is completely unclear. I bought it for my TV to get room correction from the optical input. Well, let's repeat ourselves. I'm not defending Topping. It's a bad mistake and should be corrected. I'm just saying that it's easy to get around it under Windows. It's sad and unpleasant. But it's easy and possible.
Hardware EQ is more convenient for use with headphones and speakers, and finding a user-friendly EQ application for Linux is not easy.
 
After using FW V15.69.22.69 + Driver V6.16.0 via USB at 32/192kHz for 4 days, the number of times I experienced distortion was 0 during normal daily use, over 10 hours a day, using Foobar2000, Spotify, Netflix, YouTube, and various program notifications.
I also switched between speaker and multiple headphones.
Everything worked normally.

With all previous FW versions, I would have experienced distortion 1-2 times a day.

As a user, I am interested in the functionality of the device. What are the extra features for me if the device is faulty? Douk works perfectly, while Topping is unusable for my use due to errors. DX1 II may have a lot of features, good measured parameters, but if Topping does not fix the errors, it is a waste of money.

Plenty of devices are not usable for my use. That doesn't mean I say they are alpha products and people should avoid them.

If by now you have not understood what I am saying, please move on and refrain from complaining about the same thing over and over.

You forgot the "for you" part again. See where you are going wrong?
