Thx for sharing, I meant what is your source before su6. Also did you have a power conditioner to the u16 power cord?How do you feed power to the su6?

Lumin U1 mini is the source, no power conditioner. DIY PC to SU-6 from a power strip.

I'm warming up to trying a SU-6. Uses same Windows driver as the SU-1/F1. I have two F1s and and a SU-1 and they are flawless in operation.

Thanks for the recommendation. Bought a 1A HFT Supreme fuse that had been burned in for 300+ hours and it definitely improved the sound quality. I never imagined a fuse would do this until I read this thread, It was well worth the $50. My Elac Navis speakers have never sounded better. U16 with HFT Supreme fuse, Pangea Premier HDMI cable and LKS DA004 have great synergy with the Navis.

Now I want to upgrade the power cord. Anyone have recommendations for the U16 here? Maybe $50 range?

Looking forward to see the differences between U16 & SU6.
Thanks,

I'm afraid it wont be so cheap with cables to have good result

In my system Furutech S032 cable on U16 worked well. Better than Acrolink and black DH Labs I also tried on it. But each system has different needs.

The best if you can borrow or rent few and try.

There is a jumper J35 inside.
Is there any function for this jumper?
I heard that the new shipments has taken out this jumper.
Any body has any comments?

I recently acquired a Gustard U16 to complement my Gustard A20H DAC/headphone amp. I needed to move the J35 jumper within the U16 in order to obtain compatibility for DSD playback over I2S with Gustard's A20H. The need to make this jumper change was relayed by Gustard support and did resolve this compatibility issue.

Hi DBMan,

When you say move the J35 jumper - do you mean remove it altogether?
I do have problems with DSD playback on my SOTM streamer - therefore am thinking if this jumper is the culprit

Thanks

There are two jumpers, J35, which is on or off (mine is on), then the dsd flag jumper behind hdmi, which has three positions.

You don't remove the J35 jumper - but reposition it. In my stock configuration, the two-pin J35 jumper was attached to only one pin, thus the associated circuit was open. When you move the J35 jumper, it will short the two pins together and close the circuit. It is akin to the old CMOS clear jumper on PC motherboards.

I wrote to Gustard to ask about the electrical function of the J35 jumper, but they are on holiday for two days. Gustard did send me a procedure for taking apart the U16 to access the jumper. If you need it, send me a pm with your email address,

If you're running linux on the SOtM streamer, the U16 is not properly recognized by the OS for DSD playback. SOtM is working on a fix. I would look for an update in the next Eunhasu release after v4.59.

If changing the J35 jumper provides a solution, please post your results.

Was in contact with May - 4.59 was suppose to be the fix - it didn’t work. May went radio silent after that. Thought of looking elsewhere for solving this. Will probably try the procedure out and update the group here.

Recently, they were busy preparing for and attending AXPONA in Chicago. I'm assuming it will take another couple of weeks or so for a release.

I received the following information from Gustard technical support with regard to the J35 jumper on the U16:

1.The J35 will not be eliminated.
2.The electrical function of this J35 jumper :

Mainly the frequency of the mclk signal in the iis interface, when the j35 is setting, it is 22/24 MHz, and when it is open, it is 90/98 MHz. When A20H is using input with IIS, MCLK is fixed at a frequency of 22M or 24M. Therefore, when connecting U16, you need to plug the J35 jumper inside U16.

The reference to the A20H is the Gustard A20H DAC.

My experience can't confirm that. 0.3m wireworld cable was only cable that length and was the worst I tested. Other much better was 0.6 & 1 (never tried longer than 1.5m).
For me the rule is same as for any other cable. Important is good quality conductor, geometry and insulators.

Considering buying AQ Carbon, which length did you try? Worth it, yes, no?
