Which splitter to use with turntable for both Sonos and existing speakers?

I have a Sonos Port and Sonos Five on the way and am hoping to use them along with my existing turntable (has its own pre-amp) and also my existing amp/speaker setup.

Ideally I want to either use the turntable with the Port/Five combo OR with my existing amp/speaker set up. The turntable has an RCA cable coming out of it with a stereo pair of male plugs at the end. So I would need some sort of splitter so I can divert these outputs to both the Port/existing amp.

However I am a little confused about how to achieve this. I see you can get a switch box which gives you two outputs and you then need to switch between them. I guess this would work ok, but this requires you to manually press the button to choose your output every time, whereas I would prefer the signal always went to both the Port and the existing amp.

There may be basic cable splitters which do this, but then I would be concerned about loss of signal.

How do others split the signal in this sort of setup?

Are there any other inputs to the MARANTZ that you want to play through SONOS (such as a CD player or tuner)? If not, I recommend that you connect the turntable to PORT’s Line-In and connect Line-Out to a MARANTZ input other than Phono. You will have the ability to play the turntable anywhere and the ability to play online music services through the MARANTZ.

I would connect the turntable to the phono in on the PM6007. Then connect line out of the Port to Recorder input on the PM6007 and Recorder audio out on PM6007 to line in on the Port. This route you will be able to play all Sonos source on the Marantz and share the turntable and other devices connected to the Marantz over Sonos.

This works, but the downside is that if playing the turntable or CD player through Sonos, you need to turn on the Marantz, select the correct source, and turn the volume right down to prevent out of sync audio coming out of the passive speakers.

Keep your settings and connections as they are BUT switch the Marantz to tape-monitor so it is playing the sound co ing from the Port.

There was no indication in the PM6007 manual that a Tape Monitor function is offered. Since tape decks are a faded technology, the Tape Monitor function is not supported on many current amplifiers.

There is a ‘Recorder’ Input on the amp, , but not really clear from the manual what the point of the ‘Recorder In’ input is. It seems to work the same as all the other inputs on the amp.
