shouldn't it be here more or less dynamical, because the X9 detects the headphone impedance?but they didn't write anything about the output impedance of the unit when it comes to headphones.

Perhaps this could be possible with a firmware update that gives the option to set one of the other USB ports as USB-out, some DACs already have this option in the menu.everything that I need except a USB digital out....so close.
Never seen dynamic output impedance. The HP Amp chip supposedly has a high output impedance.shouldn't it be here more or less dynamical, because the X9 detects the headphone impedance?
Hopefully someone else has oneMy multimeter is broken and I don't have spare resistors to apply the load sadly else I would!
(Best bet is to start with an EQ to Harman and then tweak from there if you need to increase or decrease bass, and maybe some low Q changes elsewhere, this seems to work for most people, so basically it's an Oratory EQ. If you're tweaking random stuff on a stock headphone based on just listening to it (not using measurements) then you'll end up wrong & it'll take too much time & effort. Anyway, last post from me on this topic as don't want to derail the thread, hence why all this is in brackets. I can probably see you're not a typical ASR member that goes off the measurements.)EQing is energy though, I went through several days of trying to get Peace/APO at a level that sounded good to my ears when I had the Ananda Nano, there just wasn't a balance regardless of how many things I adjusted that sounded nice to my ears that balanced the bright Nano signature to something that worked well with all music as opposed to just some music.
Throwing all that into the bin and getting the Arya Stealth by comparison was much simpler and removed the need to use any EQ out of the box unless I specifically wanted a new sound signature for whatever reason. The profiles in the X9's HP-EQ do a good job and refine areas of the sound for sure, but bypass sounds the most well balanced to my ears and through my headphones, so bypass is my favoured method on the kit that I have.
Sorry, had not heard or seen that. Commonly used term (not in a derogatory way) by many YT audio reviewers. I only asked because seems a new brand name pops up every month.This community is pretty clear about not liking the use of the term Chi-fi. Probably a good thing for you to consider not using around here.
Right, that's seems to be the case, I guess @amirm possibly got confused by the naming convention of the gain modes, you guys really need to update them to low/medium/high the same as other headphone amps as this is a little confusing.
What is the actual output impedance of the HPA?We will update the gain mode naming in next firmware.
I know that some people genuinely do not mean to imply anything derogatory with that term. However, I've been around in these online audio communities prior to the use of the term and I can assure you that it was not intended as anything but an insult.Sorry, had not heard or seen that.

You and I bothThanks for the great review Amir.
Interesting device but I am still keeping the RME despite its interface that I hate with passion ..
I see this as a component whose best function (for me) would be to serve as a great Headphone Amp (which includes a very good DAC & DSP in the same single unit) with an excellent form factor to sit on the desktop of a home office PC where you have Roon or other music listening software installed. Of course, it could drive powered external speakers as well. In fact, I think it might be my next upgrade just for that purpose. It measures better, is more versatile, and competes well with many units multiple times its cost.Yawn, yet another well-measuring DAC for a bit over $1000.
This is a review and detailed measurements of the Luxsin X9 stereo "smart" balanced DAC, preamplifier and headphone amp. It was sent to me by the company and costs US $1099.

Luxsin is a new brand for the Zidoo/Eversolo company and focused on higher-end audio products. In this instance, we have a gorgeous 1080p touchscreen display that lets us navigate through rich set of features and visualizations including that nice VU meter. Further, due to inclusion of Wifi, you can control the unit using an app or with web interface.
Balanced headphone output is provided including the ability to automatically enable filters to adapt your headphone to that of Harman curve. Failing that, you can program your PEQ. Alas, I started with an older version of the firmware where these features didn't seem functional.
I am starting to call DACs with such value added features, "smart."
Back panel shows other cool features such as HDMI and analog inputs:

Conclusions
The X9 sports a beautiful and functional display and menu system. Inclusion of Wifi means you can program and interact with the unit easier using the App or the web interface. Programmable EQ system lets you adjust the headphone response (or speaker) at hardware level, making it functional with any source system/app. Analog input and inclusion of HDMI means you can fully integrate all modern and vintage devices into it.
The price is up there and initial software bugs I found, unexpected. Compared to typical high-end DACs though, the X9 is much cheaper and far more functional.
I am going to recommend the Luxsin X9.
