@cmb13 I have a C2700 with the DAC2 module running into MC275s. Do you know which device is decoding the streaming music? Is it the laptop or the C2700? If it’s the laptop then it will never get beyond 48kHz. The DAC2 module is capable of hi-res files up to 32 bits and 384kHz through a USB connection. Roon software will let you use the laptop to stream Qobuz, Tidal, Spotify and any downloaded Apple music files you have on the laptop to the C2700 and use that Dac to decode. I started off using a Mac mini set up this way and it worked great. It also gave me time to set up my system using a dedicated streamer using the C2700 dac. I still use the Roon software (it’s brilliant) and let it manage all my music files. It’s also cheaper to try this software than spending thousands on a high end streamer to figure out if you can hear a difference in your system.
