Holo Audio Spring uses an XMOS chipset but my forthcoming DAC for my room headphones listening is an Denafrip Ares, this is an Amanero USB chipset. Does ROCK has any issue support it? Is there’s a SQ difference between the two chipset? Thanks

From a compatibility point of view, XMOS is preferred for Linux DSD - the Linux native DSD project is actually named as xmos-native-dsd.
For status update of issue(s) of Amanero native DSD on Linux, scroll to the bottom of this:

It seems that with new firmwa… re Amanero Card is supporting DSD native in linux. These are the data given by Amanero:
OEM Combo384 default VID=0x16d0 PID=0x71A
To enable/disable native DSD on Combo384 an USB Control request must be sent to endpoint 0. This procedure is supported on all firmware versions.
On firmware_1099rc1 an USB alternate settings "2" with a native DSD endpoint is supported.
The control request is of type Vendor to the Device.
bmRequestType=0x40,
bRequest=0xB1,
wLength=sizeof( struct VAD_DATA ),
Data is a variable of type struct VAD_DATA
struct VAD_DATA {
```
unsigned int command;
unsigned int length;
unsigned int buffer[64];
```
};
To enable native DSD
command=0x8000
length=0
buffer=undefined values
To disable native DSD
command=0x10000
length=0
buffer=undefined values
I think it’s quite likely that the version of Amanero firmware your DACs have been using is not capable for Native DSD on Linux.
Yes, you will likely have to flash it in order to use it with Linux native DSD. I still recommend you check with LampizatOr before doing this, however. The thread I posted above still indicates some sort of outstanding issue, though not on LampizatOr DAC.

From a DAC designer, Amanero jitter performance is ok at 96k and below but after that, XMOS will take over. Amanero power decoupling needs to be upgraded and I2S changed to UFL…
