In everybody’s defense,

Parametric?

is not really a question, even though it ends with a question mark.

Just to be sure, did you mean to ask whether EQAPO for Windows supports parametric equalization?

Unless you wanted to hurt the flies, that was a question.
 
None of which will make an audible difference. Also note that the Qudelix 5K's actual audio performance with the correct sample rate set is better than in the original review you linked, as can be seen from these updated measurements.

Better within worse I would say. All issues are still there: noise components in audible spectrum (see FFT), noticeable inequality of THD+N and SINAD between L and R channels - around 2% in both measurements (interestingly that it flips based on sampling frequency), still high THD+N and low SINAD.

It is fairly easy to reveal these noise components within audible frequency range if you create a sweep for frequencies [1 - 22050 Hz] sampled at 44100 Hz with Audacity for example, play it with any bit-perfect player and record the result at some high frequency (96-192 kHz window is ok), then check the spectrum of the result (Audacity allows it too).

You will not immediately hear audible difference but these noise components act as unwanted EQ at different frequencies and affect and change sonic image by colorizing it with that noise. Amir's measurements help us understand how transparent audio devices are, in general we want to hear music, not music equalized with additional noise, we could use EQ for that instead :) The lower the THD+N and the higher the SINAD, the more transparent the devices are for playing music. Achieving these values is a challenging task for the hw developer and they allow the result to be assessed: whether the task was successfully achieved or not.

All right. At the risk of being the third one to misunderstand it, check the first sentence in the Summary tab here, where it says:

Equalizer APO is a parametric / graphic equalizer for Windows.

Sincerely hope it helps!

I asked a question! This is a good answer! THANKS


PS. And going back, I see that Kenji added a photo to his answer after I had read it! And this photo is so clear, that I wouldn't have asked the question again if I had read it yesterday!
 
It's not the first, by far. There is RME's ADI-2 DAC series (targetted to hifi, not pro), the Topping D50 III and the Qudelix 5k.
Hi,
Maybe the fiio BTR15 can be added to that list ?
Allows for PEQ from app and delivered much more power...
I own it and it works quite good to my ears :)

But as a great day of neutron player, despite it's super ugly and messy interface, I'd gladly give this one a try !!!

In my opinion Neutron Player interface works well with Android but is not immediately intuitive to PC users, the interface is more tailored to Android touch screen useage, but once you know the layout then it's ok on either platform. When you first use it, then it feels a little weird!

Is there a Windows version? did not know that! Yes, Neutron interface is quite complex (confusing!).
For Windows, Roon lovers can use Roon. The rest should use Jriver (one off $70), or for free, there is Foobar.
Jriver is very very good and clever! everything is included, no add ons. It can install a Virtual sound device on Windows. This can be used to provide DSP (PEQ, room correction etc.) on a system-wide basis. One can route everything through this sound device, it will go through Jriver engine, apply any DSP, and output to a sound device of choice, or stream it!
Now, there was/is a company called iriver! not affiliated with Jriver. They used to make a tiny music player called Clix. Neutron V1 shell design reminds me of it.

Yep, Neutron Player through Microsoft Store on Windows.

Not only, there is Neutron Player Win32 version (and Neutron Recorder too by the way) with license via PayPro and authentication via Neutron Console:

Unlike Windows Store (UWP) version Win32 version has Direct USB Access functionality fully working, thus you get native DSD. Also you can select ASIO devices for output (ASIO DSD is in to-do). Win32 version is using Win32 File I/O and therefore scanning files very fast (UWP is using Microsoft's special File I/O, just like SAF on Android which is super slow).
 
Chaps - sorry to ask one of those bone-headed questions that irk enthusiasts but is this now the pick of the dongle DACs in this price range? I'm going to buy one now, and don't want to do a PhD on it, just buy one plug it in and listen. Looking at what's readily available on Amazon in the UK right now it's the Fiio Ka17, one of these, or the Fosi DS1 is on sale. Range of cans, but mostly 650s, NDH20s, and Senn HD300 Pro. Mostly for use with a laptop so not too bothered about power consumption. The Fiio looks like it's probably the best but an overkill for these headphones?

If you don't need balanced output or Bluetooth and have the money. It's a nice piece of hardware. It's likely more that you need based on those headphones and usage.
 
The Neutron has to be connected to a phone or player by USB cable. Where would the phone be, and how would a clip work with that?
For example, phone - in the pants' pocket, dongle - somewhere around the middle of the trunk. This way cable between the dongle and the phone is not hanging down to your knees while phone is in the pocket and, at the same time, phone can be taken out of pocket and used freely without disconnecting it. Use a relatively short cable, say, 1.5 ft or so (depends on the one's body size).

For sure I'd not want to put another device in the same pocket together with smartphone, this is just asking for trouble. It'll be funny if the only reason Neutron HiFi DAC V1 is quite big is because of the mostly useless screen.

Configurator app is for computers (windows, linux and macos).
I've checked the user manual and it seems you are right, it doesn't have any way to configure it from a smartphone? Then it is a nail in the coffin for the portable use scenario, all talks about dongle and portable use are simply pointless. This is a device that can be used only stationary and only with computer. And given its per-channel EQ abilities, it will probably be good for speaker room correction. But then one can easily use EQ on a computer and full size desktop DAC - which will provide even more features, quality and be cheaper?

Why? Your Q5K meets all your needs right?
Right, it does. However, I believe there is always a space for improvement. And in general, the more options and more competition, the better. As I said, I'd probably switch Qudelix-5K for another device that has the same features but offers significantly better measurable performance, even if don't hear the difference, as long as price is reasonable. But this device is certainly not it, in fact it is IMHO mostly in no man's land. But this is kind of what I expect from any first device of any company, this is normal for V1. This DAC shows potential, this is what's important. I was in fact very, very surprised that Qudelix-5K, which AFAIK is also the first device from Qudelix, resulted so well rounded without huge flaws.
 
I understand that Q5K is mentioned here as one more portable DAC having an on-board DSP but if you refer to earlier @amirm's review of Qudelix 5K you will find that this device shows much lower audio performance for 3.5mm jack which is not even close to DAC V1's. Not mentioning absence of support of 176.4-384kHz PCM, absence of DSD, and support of up to 24-bit PCM only (no 32-bit Int PCM). Therefore, it is like comparing oranges and apples. DSP functionality of DAC V1 went far either.

The price point (as general comment for a number of preceding posts mentioning price). DAC V1 is a very functional device and it comes at cost, of course. Every additional functionality contributes to the cost of the device because it involves additional components and increasing complexity of production - OLED display, auto-orientation of indication and virtual media buttons by double-tap detection with accelerometer, support for inline-mic and in-line media buttons (requires mic preamp circuit for ADC), dual clocking mode with ultra-low phase noise and very stable 2 SPXOs (which were designed and developed specially for DAC V1 by IC producer), low-profile gold-plated 3.5mm jack, powerful DSP (involving fully-fledged MCU and not just USB controller optimized for interfacing with DAC chip), small size of enclosure (involves 2 PCBs and thus increased cost of production and assembly), rounded enclosure at all angles (you probably noticed that there are no sharp edges), scratch-resistant display (involves Gorilla Glass 3 material), development and support of NConfigurator companion app.

It is not mass product and involves a lot of manual labor, I would say it is an artisan product. For example, rounded enclosure of such small size is a challenge for the producer, to achieve absence of edges and rounded corners it has to be polished manually. The same goes for Gorilla Glass 3 panel, especially with the requirement to have polished edges of a such small item. An etc. This complexity can't be free, we all live in a real world and know it.

One may argue - why do we need all this complexity, just provide USB DAC with excellent audio output? My counter question then - there are many excellent fairly cheap USB DACs already, why do we need one more similarly priced USB DAC with similar excellent audio output but the same "dumb" (as wisely noted by Amir)? It`s just pointless. And that's the idea of DAC V1 - be a very functional, smart, portable device with ultra-precise single-ended audio output without compromise in quality of components and materials.
I ought to start by congratulating you on an excellent product. I think it's excellent value and there isn't much competion in it's class. On the performance over the Qudelix, I think you are right in theory, but if one is using this 'on the move' then the Bluetooth connectivity of the 5K definitely makes it more user friendly than a device that requires a usb connection. In this use case the 5K comes within 4db of transparency to the 44.1 khz ldac codec with the dac section running at 0.4 volts. That gives upwards of 85db spl using a typical iem, which is plenty. The plastic case on the Qudelix is also highly functional, it's light and the Bluetooth range on it would likely be very impaired with an aluminium case. This is splitting hairs though really as I'd strongly recommend the Dac v1 to anyone needing a portable DAC with eq and usb input- I personally think we all need one of those;)

How you'll use one without an app to control it? This DAC will be unusable on the go until an app for smartphones will be developed. Listening on one headphones at home, connected IEMs, left home - and discovered that you are f...ed because EQ is configured for these previous headphones and you can't do nothing about this.

Do not be so fast with you conclusions. Mobile version of NConfigurator will be merged into Neutron Player on Android in the future once DAC V1's optional functionality and DSP become stable. iOS does not support direct communication to USB devices, therefore mobile app version will be limited to Android OS.

You configure DAC V1 once and then use it endlessly without a need to configure it again, unless you have a strong need for that. Therefore it perfectly fits portable use scenario.

It'll be funny if the only reason Neutron HiFi DAC V1 is quite big is because of the mostly useless screen.

Your guess is false. OLED display is placed on a 2nd PCB which is placed on top of the main PCB - there was some free space for that. The height of the enclosure did not suffer from that because the main limiting factor is the size of the 3.5mm jack.

So it's not possible to switch between the different presets on the go?

Oh, really? How will one switch between EQ profiles?

Good. And bad. Bad, because it means one will need Neutron Player. But if one uses Neutron Player for playback then one doesn't need EQ in a dongle. And bad because iOS users, there external EQ in a DAC is most important, will not be able to actually use it. Looks like it really, really needs Bluetooth - if not for playback then at least to be used as a remote control.
