I bought 2 Sonos AMPS & set up a network when we moved to this house w/2 sets of built-in speakers, and that part works well.
Our legacy system is a Denon CD player and Rega RP3 turntable that had been connected to a now-discarded amp, which had been wired to KEF Ls50 wireless speakers. So, I bought a Sonos PORT and connected it to the CD player and added it to the network. So far, so good.
I then bought a Music Hall Mini preamp (supporting MM cartridges) and inserted it between the turntable and a used Sonos CONNECT (Gen 2) I just bought as well. I successfully reset and added the CONNECT to our network, but no sound emanates from the turntable, nor does it when I plug it into the PORT.
Which leads me to believe I have a preamp/turntable issue (preamp was $99 from Crutchfields), but perhaps I am missing something w/regard to the network. Any suggestions welcome.
