As discussed, I will be testing a long version of the Matrix USB from Cerious Technologies.
Test equipment list:
Computers:
MacBook Pro
Media Server - 6 cores Intel HEDT CPU, dedicated USB card, will try both motherboard USB headers as well, as well as dedicated USB ports.
Main Server - 16 core AMD ThreadRipper CPU, 20 TB of M.2 SSD storage, dedicated USB card, will try both motherboard USB headers as well, as well as dedicated USB ports.
USB Devices:
Musical Fidelity V-Link USB/SPDIF convertor - this unit actually powered by the 5V rail from the USB cable.
Musical Fidelity M1 DAC - USB input
Wadia di122 digital decoder - it has USB input
Bryston BUC-1 USB/SPDIF convertor
Berkeley Audio Design Alpha USB - USB/SPDIF convertor
Mark Levinson 30.6 reference DAC - needs either the Bryston or the Berkeley to feed via AES/EBU, does not has USB input

Will give results to Bob and will share with the forum with Bob’s permission.
