I was told by seller this unit doesn't support DSD 256 with Apple. Can someone please comfirm?

.....

Adding SU-1 makes DSD256 (DoP) from Mac be playable via HDMI LVDS I2S/DSD.

That would be the Singxer SU-1: https://www.shenzhenaudio.com/singxer-su-1-usb-digital-interface-with-xmos-xu208-cpld-dsd256-dop.html

Yes, but the product description is incorrect.  It DOES SUPPORT DoP256.

See my post for the proper firmware version and the dip switch settings for LKS.

With the firmware 2002b and Linux kernel 4.11.12, I have just succeeded in playing up to DSD512 with Gustard DAC-X20 via I2S/DSD input (HDMI connector).  This means it should work also with MH-DA003/004 in case a correct connection via I2S/DSD is given.

MAC Audirvana is up to DSD256.  DSD512 is not highlighted in Preference.

There is nothing to lose when you update the firmware of comb384.  You can change it into any available version at any time.

When you are playing a DSD512 track, does the Gustard display the correct rate on it's display, or does it show something else?

The correct rate.

I am not an owner of MH-004A, but believe it uses Amanero combo384 USB-I2S/DSD board.

First, update its firmware to the latest 2003be_71A.  The instruction is given on Amanero's site for oemtool117.

 

To the best of my knowledge, Audirvana+ 3.1 with its new feature of making an DLNA renderer as its output brings the best sound quality.  You can play DSD512 native in combination with combo384, if you set up a Linux DLNA renderer additionally.  I have already tested this in my environment.

Otherwise, Mac USB output plays DoP only.

@MINORISUKE I looked up the amanero oemtool117 it seems to be for windows, I am on Mac, maybe i missed something. Thanks.

The firmware update can be done only on  Windows PC, unfortunately.  As you may be aware, the firmware is independent of the OS.

This firmware update tool requires an Internet connection.

What frustrated me is the noise I keep experiencing with this new dac, i keep getting these static like noise at the beginning of a track, and flushes of white noise for a few seconds.

Unless you update the firmware to 2003be_71A as I indicated, I am afraid USB-100 (= the same Amanero chip inside) will give the same result.  I am its user.  See my posts in USB-100 thread for the pins for firmware update.
I suggest you update the firmware of both MH-DA004 and USB-100 with a Windows PC before you start trying or investing for anything new.

 

De-emphasis function is not intended to be used like this.  It is for CDs with emphasis which could be seen in the very early days of CD.

 

DoP volume control on the player software does not work theoretically.  It must be bit-perfect at the input point of a USB-DAC/DDC.  Otherwise the USB-DAC/DDC cannot judge whether it is a genuine PCM or a wrapped DSD.

 

And try A+ 3.1 with DLNA renderer output.  It really brings you a different world.

In addition, you have to specify the output specifications manually for DLNA renderer output, which may solve your issue automatically.  You can send me a personal message if you are interested.

I do not own MH-DA004.  However, all the Amanero boards look similar.

I uploaded a correct link (at least correct as of today) for USB-100 in its thread here in CA.

A Google search for image "combo384 lks" shows lots of pictures.

For example, you see under this link x3 contacts, one of which is a rectangle.

Use the this rectangle pin and its adjacent round one among x3 contacts.

Does 2003be_71A have correct right and left channel?

You had better ask this question below:

https://github.com/lintweaker/xmos-native-dsd/issues/12

There is no channel swap in my environment.
