USB Jcat Card for D.I.Y Mounting


I’m finishing up to mount an audio server in a Streacom Alpha 9 box on the base of an MSI motherboard with a Core I5 10500 T and 16GB DDR.4 2666 memory.

I have Windows server 2019 as Os and Roon installed on a samsung EVO 970 plus NVME SSD

I have 2 Hi RES Music Storage SSDs in Flac 24-96 and DSD 128 and 256

I installed a JCAT NET FEMTO PCI card that is powered by a linear Volt 2.5 A power supply

I must now install a 2nd USB JCAT card also which will be powered by a linear power supply in 5 Volt and 2.5 A also

the server will be connected to an audio DAC GD Audio-GD - R8 2021 - Discrete Balanced R2R Ladder FPGA Accusilicon DAC - PCM / DxD / DSD either USB or I2S,
What is the best choice if I2S have to go through a converter?

I used to use a Lumin streamer/DAC as a Roon endpoint and decoded from the MQA of Chez TIDAL?

n(having the Lumin and using me from the audio server to the DAC audio GD is what will be roon Ready and MQA compatible?

thank you for your feedback


You have a lot going on here and I am not familiar with some of the components you mentioned. My only feedback is that I am using the JCAT USB Isolator between my Lumin U1 and the McIntosh DA1 DAC and the sound is very good. BTW the USB Isolator is powered by the USB2 port so it does not need a separate power supply. Best of Luck on your quest.
