Audirvāna is fine, Tidal is fine, Apple Music is fine, then I don't have any Apple shares (I've only been a user since 1988) so you're right to change if you don't like the Mac.
I have two systems, the desktop one has been using macOS exclusively since 2008. This is the first desktop DAC I have bought, previously I was using the internal mini Mac m2 Dac. I wanted to try a dedicated one to make the most of my Hi-Res library. Effectively the external DAC gives something more. I have not finished my evaluations yet, because I ran into this problem, and I want to solve it. I have nothing against the Mac; I love Apple systems.
 
There are several programs that get exclusive access to the DAC. Foobar2000 is one of them as is the Tidal app. No other program can use it then. The sample rate in the Audio MIDI Setup is always the same as the DAC shows. At full volume and with the right sample rate and bit depth selected, macOS just passes through the audio stream to the selected audio device. If no other device is using the device, there is no manipulation of the signal between source program and DAC, i.e. transmission is bit perfect.

I have had no problems with sample rates above 48 kHz streaming via qobuz which selects the sample rate. I have tried the same things I did in foobar 2000 with qobuz where there are no problems at all with buffer set to 0 seconds.

I don't have Audirvana.
I don't like streaming music, so I appreciate your input that excludes malfunctioning Macs. At this point the problem occurs only with Foobar and its W. drivers. I need to review my Hi-Res library on Windows so as to rule out that it may be corrupted, although I use software to check on the correctness and of the recordings, the Dac I bought to listen to, and see the differences of the M2's internal Dac, beyond 48 kHz at 16 bit.


PS: In exclusive mode, the Dac cannot be used simultaneously by other players. Not using streaming I use only Foobar. I will do more tests today. With the buffer length at maximum I have already solved some problems on low resolution tracks.
 
Connecting from a Bluesound Nodes Coax output into the SMSL D6S. Every 5 minutes the quality goes down to 2-bit and I have to reboot or change the input back and forth like in the video. I attached the speakers directly to the bluesound and there were no issues(other than I nearly blew my speakers ) Anyone ever had this problem, its drivin me nuts.
Any help appreciated.
You may try a higher DPLL value (especialy with 192kHz)

I have two systems, a large one in the living room and a desktop one in my office where I work. I built the latter around the Mac, first with an early 2009 24" iMac, then with a 2015 27" 5K retina iMac, and now with a Mac mini M2. I have been a Mac user since 2008, I also use them for work. I decided to try this DAC for Hi-Res mainly, compared to the stock DAC (which is still connected to my amplifier via mini jack - rca, so I can see the difference in real time with the SMSL d-6s). This is my first time using an external DAC on the M2, so I want to make sure it's worth it. I'm quite fussy about music, so I'm not easily satisfied. I don't want to try Audirvana because in 7 days I don't have enough time to do all the necessary tests, and then they want me to create an account anyway.

I tried higher DPLL values, tried optical, tried Tidal and my local NAS and they all have that same problem. And my bluesound node is up to date. Will probably have to send the SMSL back. Too bad cause it sounds fantastic.

I'm honestly overwhelmed by the amount of DACs from this company. Looking for a DAC up to 200 Euros. It should have balanced Outputs, the typical USB+optical+SPDIF inputs and a functional remote.
I would prefer the form factor of the M300SE, is there any reason to choose the D6S over the M300SE?

Topping D50 III is far away the best as overall at this price point now. I wouldn't have got the D6S at all if the D50 III was released earlier.

In what way is the D50 III better? I mean, I can see it perhaps has better build but if you're not interested in the EQ are there any other benefits?
 
@VientoB I've read/watched a couple of reviews and for me the EQ + form factor are selling points. Don't know if/how I will use the EQ in the long term, but if it holds up to my expectations this could be very cool for having the same sound on different devices (although only through USB). Then the form factor is another small bonus, plus the remote being Bluetooth, so no direct line of sight required. Sound-wise they are described as pretty similarly good, so I wouldn't notice a difference anyway. Maybe I missed something..

Try usb-out from node to D-6S (with appropriate adapters). You may have to reboot node before it detects the usb as output.

Auto-standby, lower power consumption, smaller size
 
optical output cutting bits... see reviews here, still not fixed with FW update
Was going to get D50III but the optical bugs prevented me.

What's the best overall DAC under $500 that's state of the art, fully-balanced, with Bluetooth and no pops/clicks when changing bit rates?
 
What problem would that be?
Get yourself another email (iCloud creates them automatically for you...).
yes but the data is always mine.... I don't need a player that shows the covers, I need a reactive player because I listen to 100 things in less than 10 minutes. It seems to me like a sort of post-Jriver media center that is pitiful
 
Try it…
P.S. Non puoi avere la botte piena e la moglie ubriaca

I'll give you my brief experience. I was also intrigued by the Topping D50III and waited to see how it went. While waiting, I got the D-6S because it has been out for 1 year, therefore, it has been tested by users who have highlighted its strengths and weaknesses. I was amazed by the D-6S, so much so that I wrote here about the only flaw I found, which we later saw did not depend on the D-6S but on the Foobar2000 drivers. I can tell you not to go beyond 200 dollars, because the more you go up in price the more they start to give you "accessories" and therefore it no longer becomes a simple DAC but something else, except for the R2R DACs which I haven't tried yet. If you need more inputs, a preamp etc. then go up the price otherwise it's not worth it. I haven't tried the AKM processors, I wanted to but I saw that you pay more for processors that are less easy to produce, given the company's problems. The "cheap" DAC models that have AKMs save on the power supply phase, and have problems (E30 ii lite for example). I wanted to try E70 Velvet, but I gave up. The dual chip solution is not always the best, just like the pro models. Just read the previous pages of this and other topics. Therefore, it is worth risking a large sum if you have the ability to resist it if it doesn't go well. As for EQ, I have the Eversolo DMP A6 which has a software EQ, compared to the A8 (which I wanted to get just for the EQ processor). The EQ of the A6 is not the best, it dirty the signal. I used it little. Ultimately my EQ, on the main system, is the toe-in arrangement of the speakers (after looking at the polar diagrams). But you can also do EQ with amplifiers, if the speaker allows bi-wiring (with the separate tweeter circuit). So, EQ depends on many things for desktop use you can use different software. For Hi-fi systems, it is more complicated and you need to know more information (room, speakers, amplifier, etc.).

All in all, the d-6s may not be aesthetically the best, but it sounds good. The topping d50iii I wanted to try it but decided not to, because the optical output is important to me, also with the Mac I think there are no hum problems, but on an assembled pc it depends on the PSU I'm afraid (I wanted to do this test, but the optical output blocked me, and I'm not sure it will be solved with the FW). The d-6s doesn't pop at all to me; it's paired with a REGA IO (which has lousy measurements, but sounds good to me and doesn't heat up like an oven). The pops you hear on the sampling change may be related to the recordings. I happened to hear them only with Flacs made from vinyls, which I deleted. So you should buy one and try it out, if possible get it on Amazon so you can send it back after the 30 days if you see it doesn't satisfy you.
