External DAC with a receiver

Hi just had a quick question. Are you able to use your external dac with an AVR?

I have an oppo 105 and a Marantz sr6009. My preamp no longer works and was hoping to use the Marantz as preamp only.
Setup:

2 Channel: Vienna Acoustics Mozart Grand, T+A P 1230R, Primare SPA21, Oppo BDP-105
PC: Vienna Acoustics Haydn Grand, Cambridge Azure 650A v2 , Peachtree iDAC, Denon DVD-3800BDCI
