How difficult was it to put in?

Requires experience in working with surface mount components.

Might be easier to find a shop that does smartphone repair to see if they are willing to do it.
About 45mins to 1 hour for those with the tools and necessary skills.

Get the isolators from www.digikey.com

Yes, SMD hot air rework wand, this particular set of chips was done with a Metcal HCT2-120

Thank you very much!!! I noticed that there is something like a transparent glue on the screws of the board. Is it just a mark from the factory?

Thread locker for the screws

According to the website SU-6 supports up to 32 bits but the control panel (Singxer USB Audio Class2 Driver version 5.0) doesn't show the option for 32 bits. I checked the Windows sound setting and it doesn't have it either. Does anyone know how to fix it please?

@b0bb Thank you for generously sharing your extensive knowledge to improve SU-6! I swapped the capacitors and could hear the improvement. Next mod I will do is on isolators (I need more soldering practice before I commit

Hi

My SU-6 creates a very loud pop noise only when connected to DAC via I2S (Gustard X26 pro, or Benchmark DAC-2), whenever the music starts to play or right after the music stops. Essentially, the noise pops when the front panel "Play" light goes from OFF to ON, or ON to off.

No such noise if it is connected via USB, AES, COAX....

Any idea?

Thanks in advance to the Experts!

I never experienced that effect with my LKS 004. Sorry I can't help.
Du you use the latest firmware?

I am not sure about the firmware version on my unit, but I will check tonight. If you don't mind, can you tell me yours?

It is a shame, because the sound from the I2S connection is so obviously superior.

YES, and it can even get a lot better with some mod's

Suddenly my unit will play garbage when doing DSD. PCM all fine. Connecting thru I2S (Hdmi) to my Audiobyte Hydra Vox (Rockna).

Anybody have this problem?

Connecting my DAC via USB all fine.

UPDATE: Resolved by leaving overnight unplugged.

So, I ordered a SU6 AFTER I read this thread. I had a SDA6 and returned it (and with partial store credit I got SU6) after finding it harsh sounding even after 500 hours of plug in time but maybe only 50 hours of actual play time. Now, after reading this thread that I think SDA6 perhaps needed more play time and that I will have a long wait for the SU6 to fully burn in. Funny, my SU2 didn't require any burn in time. It sounded great the instant I connected it to the D90. D90 didn't require any burn in time either. I will be powering the SU6 with a 50va lpsu with dual output. So, SU6 and a Matrix Element H will share the LPSU. Amp should be about 2 or 2.5?

Anyways, the conversation seem to have died down during the past few weeks regarding this DDC... it has been out for over 2 yrs afterall...

Anyone Here can compare to the src dx?

Please try a different HDMI Cable, and use a linear power supply.
