we import servers the 432 evo servers from Belgium these are considered among the best sounding servers out there.
We had the usb vs i2s conversation with the designer.
He said that he tested both outputs and concluded that i2s was not better and was nearly imposable to support as there are different implementation’s depending on the Dacs manufacturer.
as per USB, we have clients using the Terminator and our 432 Evo servers and getting great sound.
in order to have great sound from USB you have to isolate the Data correctly:
In the case of our servers we have separate assemblies: the CPU is in its own board, the USB card. and Clock, are isolated physically and electrically from the CPU, a special laser sintered 3d printed shield electrical isolates and further shields the CPU, and absorbs radiated noise from the all-ready low noise quad core CPU,
Even Roon is isolated, we use 3 cores of the CPU independently,
one core runs the program,
one core runs other processes,
one core handles files allocation
it all comes down to design, building a world class Server is way more sophisticated and complex then what many people think
