My DS101 is directly connected to a Onkyo PR-RZ5100.

At first I thought the DAC in my amplifier was the bottleneck, but it seems to be the Discovery. The Discovery’s tech sheet mentions different specs however: CONNECTIONS Analog outputs (independent zones): 2 Coaxial output (independent zone): 1 (192 khz 24-bit max) Optical output: 1 (192 khz 24-bit max) USB port (mass storage class): 1 USB 2.0 Ethernet port: 1 gigabit ethernet This reply was modified 9 months, 2 weeks ago by radekker.
