I dont understand why you choose Amanero USB card when there are latest products as Xmos Xcore200 chipset based cards and dsd 1024 support in native mode?
Thank you so much and soyy for my bad english.

Hi

regarding: LVDS: you can replace Amanero by making an interface board using eg LTC1518 receivers.
The Amanero is a very good sounding USB - I2S interface board and the Amanero boards has been tested against other USB-I2S interfaces.
Please see: ES9018 USB DAC - Hi-Resolution System*

As the I2S interface is standard, an other USB or LVDS interface can be used instead of the Amanero.. i guess this is up to the user to decide.

I first use the Amanero USB interface with an Intona USB isolator between the PC and this ES9038 DAC.

The sound is very good but I still want to further improve the DAC performance. I then got a SINGXER F-1 which use the XMOS Xcore200 XU208 chipset.

This SINGXER F1 provides galvanic isolation and also regenerate the USB signal after the galvanic isotation. It also uses 2 Crystex CCHD crystals.

This Singxer also use the same pin layout as the Amanero. But unfortunately, Quanghao's board has other input connector (the optical input) right next to the USB input which prevent the board to be insert into the USB slot directly. So I connect the I2s input from the Singxer F1 to this ES9038 DAC through extra wires. It is quite troublesome.

The Singxer F1 seems to outperform the Amanero in every aspect.

It is a very good suggestions that Quanghao in the future can provide I2S-LVDS input with HDMI connector (PS audio standard). So when these new USB cards with new capability become available, it will be easier to adapt these USB card to Quanghao's dac.

thanks
Andrea,

do you have PCB for this output stage? Also, is it possible to post drawing of layout if only using balanced output? how is this different or better than the "Super V/I Converter" you had for earlier projects, and that you have PCB for?

Thanks,
Doug
