Soekris Europe and therefore soekris.eu was a separate company....

Yes, we're alive.... We have been having trouble manufacturing in 2023, but now it's starting to flow again.... MrOjoRojO, what do you mean with "official business address is for sale" Do you mean domains ??? I control soekris.dk, soekris.com and soekris.net.... And yes, sometimes we're slow...

Actually it's what's called "high bias class AB", so it stays in class A until a certain output current.

The dac2541 headamp consist of a opa1656 opamp driving a discrete high current diamond buffer....

I'm here.... And are easy to get in touch with, just send an email to info@soekris.dk.... I get a lot of emails, so as it says on the website, if no response, just send it again.... But also, please read the website, I'm pretty slow at answering emails asking for info that's on the website....

Incorrect, the soekris dac1541 is oversampling, although you can choose between different filters, including one with a pretty soft rolloff....

There are a number of errors here: I2S input, there are no standard for that, and its an input needed only if you don't have anything to fight the jitter there per definition always are in the SPDIF inputs. My DACs all reclock and buffer all inputs, removing jitter completely.... Non Over...

There are, as all my DACS are sign magnitude with 26-28 bits, please read up on sign magnitude....

Yes, easily, I actually use a HD800S for test....

I'm using the HD800S for testing and demoing my DAC's, they sound fantastic on the balanced headphone outputs on a dac1541....

The reason only supporting win10 is software, win10 finally added support for UAC2, while win7 just need a driver.... I would say license a driver, like the one from Thesycon, you need a driver anyway to get ASIO support. Win7 will work just fine, even after Micro$oft discontinue support, just...

Please link or explain Sign Magnitude. Edit: I read Baldr's thread that was linked and think I grok Sign Magnitude now. Oh and on behalf of America, thank you to the Danish people for Carlsburg. DP I have a short explanation on my website, but it's kinda not that easy to understand, hope...

The keyword is Sign Magnitude.... That way you get level precision down to the last bit, which is what you really need for Audio....

Never heard that.... Resistors only really fails if overloaded, which they're not in a typical R-2R network.... I don't have spares in my designs. Chips often have redundant circuit as the manufacturing process have random defects, that way you get more good chips out of a wafer. But not often...

It's actually cheaper to make a discrete R-2R DAC than using those very expensive Analog Device chips, even as I'm sure Schitt get a good discount on them....

Result is much lower noise with large value resistors.... It's easier to make precise resistors in larger values in a chip. Those 63 resistors in the thermometer section are paralleled.... Many discrete manufacturers, like me, do it too, same lower output resistance..

New product dam1921/dam1941 coming very soon.... http://www.soekris.dk/dam1941.html

Thanks for mentioning Soekris, always nice when the bigger guys notice you.... It's fun to follow Schiit, I kinda started the original Soekris Computer Board business the same way in CA, using the same sales model, eventually selling over 250K boards.... But everything comes to an end and now...

Thanks for the nice words. But you also did a nice module. Competition is good, stealing is very bad, you should sue them because it's a clear copyright violation.

Delivery Dec 18, 2018 ?? Massdrop / Airist are welcome to contact me, I'll be happy to design and deliver a plug compatible module with same sound and functionality but better specifications, at a lower manufacturing cost (the pictured board use some unnecessary expensive parts) in good time for...

Not again, now he is making noise here after his bashing got booted from diyaudio.com, sorry to expose everybody here for that.... He purchased four pcs rev1 dam1021-01 DIY DAC boards in Jan 2015. In Sept 2016 he emailed and asked to return the units for a full refund, as he "was overwhelmed"...

From experience: Parts coming from same reels are actually matched very closely....
