There are 2 capacitors to add for any positive shunt

the first cap 1uF is on pin 1-2 OPA2134
the second cap 0.1uF on pin 6-7 OPA2134

if you use SMD caps you can follow my photo

if you use normal caps follow the Caad photo

R9 and R10 resistors are only on OP-amp modules and these should be eliminate

Thanks. I see that the 1uF SMD cap is connected to pin 1 and 2. The other cap, 0.1uF, looks to be connected to pin 7 and R31, right?

Hi,

I am not sure if anyone else experience this: I am using Audirvana on Mac (playing DSD files) -> USB -> Amanero USB -> DAC. When ever I manually change songs, the first 0.5s of the song is missing all the time as the USB tries to resync with the USB data. If I let it plays one after the other, everyting is fine. Any clue?

Many Thanks Herbert

Hi, I tried itune with all 44.1/16 wav. It is perfect.
I retry Aduinvrana plus. With 44.1/16 wav files, there is not a problem there. Problem only with DSD files.

I used the same program on Teac ud-501 with dsd files and have not encounter the missing of 0.5s.

Need to update Amanero to lastest firmware?

Many Thanks Herbert

Hmm... got problems! Opened the box. At least the DAC has survived the journey. Power cable has non uk plug. Never mind. Fitted the amanero - recognised by my linux box but no sound when playing. Remains as USB link on display but no output. Shall try coax tomorrow. I dont think standby is working properly. When powered off and on, there is lots of strange characters on screen.

I am not at all happy at the moment. Shall try different things over the next few days to make it is not me being silly.

Hi bertchai!

may be you wrong,

I've seen you at the same time using two 3.3v power supply for usb.

3.3v power from the computer first
3.3v second power from the DAC. So now you do this picture:

This jumper pulled out. do not use it! USB will run fine

see image

My TEAC VRDS10 is dead! I can not play with spdf inputs. I can only use the USB input.

You have the tracking of my payment of Amanero ( Transaction date: 26/07/2013, Cod. identification: 13000019101879 )?

Please can check your account?

For now I admire your magnificent DAC.
