Its looking as if @kuribo's public shaming has borne some fruit (scroll down to the last post) - Soekris R2R dac Head's up.... - DAC - Digital to Analog Conversion - Computer Audiophile
Haha, if he's who I think he is at another forum I frequent I am not surprised🙄. I am in shock that I actually somewhat agree with him.
Anyhoos, the DAC market is absolutely glutted right now. So many choices and permutations. Overwhelming.
Here's an update to clear up the misinformation being gossiped about here....
Soren offered to make things right free of charge. I will report back the results when they have been returned.
Tubesguy, if only you half understood....

Lesson learned. Never buy largish quantities of a gen1 product unless you know what you're really getting into. I waited till v2 before buying a pair of them. I was well aware of what I was getting into when I bought a v1 from the first batch. It really wasn't a big deal to mod the vref anyway.
The biggest issue of all with the v1 was the power-off thump that had the ability to kill loudspeakers yet that had absolutely nothing to do with Soren's initial promises of reference quality DAC. As with any new architecture there *will* be issues.

I have bought version 1 products from several vendors, like Tripath, Hypex, PS Audio, etc. without a problem but your point is well taken and indeed, a mistake I won't repeat.
I do appreciate the offer from Soekris and look forward to reporting on the results.

A great point. Still waiting for a version that uses real oscillators and not some pll synthesized contraption.
If you are referring to MSB, I think they do use real oscillators, not DDS.
Update- I received the dac boards back from Soekris. There wasn't an invoice detailing what was done- Soren, can you please detail the work that was done, either here or by PM? Thanks again.

Updated to match shipping rev1, see post #3276 & #3108. Hardware updates:
vref capacitors changed to 47u (red on drawing)
feedback capacitor changed to 499 ohm resistor (orange on drawing)
series resistor changed to 0.1 ohm (blue on drawing)
27.4K ohms resistor added to reduce plop
Firmware updated to newest version as available on website.
dam1021 v1 - The first one, really need the vref mod
dam1021 v2 - vref fixed, improved power on/off mute
dam1021 v3 - custom resistors, more vref capacitors
dam1021 v4 - new output buffers
v2 might improve with a little more vref capacitance, otherwise no mods are needed on v3 & v4. You should of course always use latest firmware.
Is this vref stuff because of the on and off plop?
Is this plop gone in V4?

The plop was fixed in v2, and no it was unrelated.
Reading this thread with interest. I hadn't come across the Denafrips before. However, if you have bought one direct from the website I suggest that you contact them to remove YOUR postcode from their sales board. Seems to me that the map on this page is an open invitation to thieves!

I would highlight the security angke here.To intact security, i would recommend to go through multiple comparisons between various top antivirus services. For combatting with hacks, malware and other security threats, you should add a shield to save your digital accessories. Research is the key before chosing any product and more for security products
