anyone tried turn the vol of your amp to max with l.k.s.004 and play nothing? is your noise obvious? my one is quite obvious. if i switch to other vacant input in amp, much quieter.

I do not have such issues

i just tried upsample to 48k 512. it plays normally but just showing un-lock. if play 44.1 512, it shows 512 as usual. any idea?

I cannot verify it because I haven't played DSD512 yet and I do not have the DAC at the moment.
It sounds like a firmware issue.
As you use HQPlayer like me (I 'm actually an official reseller for it), did you notice a SQ improvement going DSD128 -> 256 -> 512?

 

[bibo01]

Does anyone has problem getting the BW lower to BW1 BW2 or BW5 ?

I have a problem at BW5 or lower only if I play DSD.
LKS suggests BW12.

Exactly, and why is this ? Do we need new firmware or such ? Just wondering

yeh the one i bought my 004 told me anything stable at bw12 or higher is considered "pass".

I doubt it.
At higher frequency higher bandwidth is needed. BW1-5 is low bandwidth.

What do you mean by "pass"?

At reply to my question - "Did you notice a SQ improvement going DSD128 -> 256 -> 512"?

Nope, the manual stated that the lower the number, the higher the bandwidth, and the more tolerances sensitivity the input signals are. That means, the lower the number such as BW1-5 can only work with sources that generated the lowest number of errors, or has better details info retrieval at higher frequency like you said.

The manual stated that the lower the number on the BW the better the sound

I meam quality pass in the factory.
No so far i did not notice any difference when up to 512. But i will spend more time to listen seriouly.

Currently using a Singxer Su-1 with a Gustard X20 pro using I2S. Anyone have the LKS DAC004 working with the SU-1 and is so what DIP switches needed to be turned on.

I bought this DAC blind a few months ago and have been pretty pleased with it so far. It is definitely not the most user-friendly DAC, but I think its build and performance are top-notch for the price.

What would make it more "user friendly" for you? One thing I can think of is being able to set DPLL levels for PCM and DSD independently so that they switched automatically when the input did, the way the filters do

Any other suggestions? Perhaps LKS could adopt some for its next edition.

Well, for starters, they could add a (mini?) USB port for firmware updates directly from a computer instead of requiring users to physically open up the DAC and update the firmware while the power is on. I've been too timid to do the firmware update, because I'm afraid I'll accidentally fry the DAC or myself.

While that would be nice, my guess is that's not possible as the issue is with the Amanero board rather than with the DAC. However, though inconvenient because you have to open up the unit, there is really no danger. The boards (Amanero + power supply for it) are removed while the power is off. While power is applied you only handle these boards away from the chassis Only about 5 volts is applied to them. Not much chance of frying anything. Then it's power off again for replacing the boards.

Have you seen the detailed instructions originally prepared by LKS? You can get them from LKS or you can PM me with an email address.

 

[Whitigir]

Exactly, that is the amenero board design, unless they design it into another Way that can permit easier firmware upgrade. But at the moment, there is no such plan
