Sonos Port and Sony STR-DH590 Receiver

I do not have a Line Out on my receiver, other than Subwoofer which obviously unable to use for this purpose

Connecting and using the CD player and turntable to the Port is simple enough if you remove the receiver from the setup. A simple line-level switch is enough if your turntable has a preamp, just needing an external one if it doesn't. 

I’m guessing that if I did want to keep the receiver as part of my setup, I would need to upgrade the receiver to one that has a Line Out, or would I need 2 Line Out ports?

What is the benefit of keeping the receiver if you don’t have any speakers connected to it? Operationally it would be simpler to add a line level switchbox.

You can use an adapter to connect the receiver if you like, but I don’t recommend this. I would not want to attempt explaining system operation to a visiting relative. Using a line level switch into the PORT that you already have installed is much simpler both to install and operate and this arrangement occupies less space.

What line switch would you recommend for this set up?

Basic questions here.

What exactly do you want the receiver to do? 

Is there some special fuction that one does that would make it worth spending many hundred dollars for an upgrade?

Consider instead:

Phono pre-amp (may be needed):

A nice preamp is an option, most of these have the tape-loop needed for the Port and a phono input:

Switch box, a quick Amazon search will turn up a lot.

Thank you, Stanley_4

I do not need a pre-amp for the turntable. It’s an audio-Technica AT-LP120XUSB and has the Phono/Line switch.

A very different approach would be to use a stereo mixer. The CD player and turntable (built-in or external phono preamp) would be connected to the mixer with inputs adjusted to match playback levels. This would be a one time adjustment. Both inputs are always active, there is no need to operate the unit. The only discipline required is to play one unit or the other. If both are playing it will be a bit confusing for the listener.

Note that there is nothing special about this particular product. There are multiple similar products.

Thank buzz.  I am going to order this today!  I’m assuming the Sonos Port would be plugged into the mixer as well?

Output of the mixer would connect to Line-In of PORT.
