DAC AD1862: Almost THT, I2S input, NOS, R-2R

I don't have a JLSounds board but as far as I can tell my board has better isolators. XMOS used to have high noise and jitter but I don't know if that has changed with recent versions. So I have no reason to think my board would sound worse than JLSound. But there are other things to consider as well. E.g. how do you use JLSounds with AKM or ESS DAC chips in register mode (i.e. I2C) or how to add a digital volume control? With JLSounds such functionality requires an external MCU which in most cases is not digitally isolated.

Original. (From post #2180)If possible with shift registers on it.

...If possible, another request please....
Squeeze in a GND pad inline with the I2S header so a single row, 4 pos Molex connector can carry all I2S signal with GND.

@savvas
shielded ribbon cable is perfect 🙂

I don't know if it is possible to order the board from JLCPCB with the shift registers installed.

Normally I order my components with reichelt, but they don't have the 74hct164D.

Hello Tan,

How does it compare to jlsounds interface ?
Thanks

Hi Guillaume,
I did a comparison session with a friend of mine over the last weekend.
The test was done on PCM63 DAC with stackable USB-I2S, since the JLSounds and York can both be easily swapped by means of unplugging and plugging in.
Both of us thought that the difference is rather discernible, could easily be picked out.

Both JLSounds and York are powered by a regulated supply on the USB and the clock/reclock side is powered by +5VD from the DAC on the board.
The JLS sounded more open, with more space between the...

JLSounds question - v.III (current version) without isolated outputs

For use with PCM63 board, I want to have it configured like this? I think this is right but I'm still scratching my head.. :scratch:


4K7 between H1.1 and H1.3

J4 close

All “B” jumpers open

H3.9 Data L
H3.11 BCLK
H3.13 Data R
H3.15 LRCK
H3.17 5V
H3.19 power ground

You have got the Data L and Data R swapped.

Ah! looking at it I have the connector correct and the text in the post incorrect. Good catch though, thank you.

Don't forget to connect the JLSounds ground to the DAC board ground at the i2s inputs.

It is. The i2S are all coax and the grounds are connected.


Thank you! Should have it powered up later tonight.

Is playing beautifully, thank you @zoom777 for your prompt and expert assistance, is very appreciated.

And thanks @Sorenm for the PCB. I have a nice chassis for this one, it’s going to look great. 🙂

Hmmm... looking at this photo I see I've got the JLSounds powered on by the analog side of the PSU. Will change that and well as the power wiring when I breadboard.

Original Amanero or chinese clone?
If original, there seems to be a need for firmware update.

Post in thread 'USB to I2S 384Khz - DSD Converter'

I have solved the issue with the Amanero talking to the PMD100 chip. There was a firmware update for a DF1704 filter chip with reduced clock speeds in the list. I tried that and all is ok. Thanks to Domenico and his multitude of software options, this usb-i2s converter has got to be one of the most versatile of all the current popular converters available at the moment.
If it is a clone, then i am not sure what you can do.
Anyway i suggest you try the Amanero thread or contact the maker.
