Bel Canto has three asynchronous USB link converters new to CES this year starting with the mLink at $375, the uLink at $675 and the REFLink at $1,500. All three units can handle 24/192 sample rates and will isolate the music signal, and clocks, from the "harsh, noisy electrical environments of computers and music servers."

Each converter has a USB input and SPDIF BNC output, with the REFLink and uLink also featuring ST fiber connections. The REFLink adds a dedicated power supply, AES/EBU output and powered USB. All are available now.
