Bluesound Hub

My Primaluna preamp has 2 preamp outs - one is connected to monoblock amps, my question is can I use the second preamp out to connect to the stereo analog line input on the Hub?

My turntable uses an MC cart, not looking to replace my current phono preamp. My idea is to use the 2nd preamp out to send a source (turntable or SACD/CD player) based on the selected source to the hub and from there to my other bluesound speakers
