I have a question to it
I have an old Marantz amp. At the moment the WiiM pro+ is connectect via WiiM line out to my AUX 1, the selector to AUX 1 and I can listen to my stream.
I conneceted my Dual phono to the phono inputs of the Marantz.
So switching between phono and AUX 1 to listen.
On tape 1 in I connected my external headphone amp. Listen with my headphone amp, I switch the "rec selector" to "source" so I bypass anything from the Marantz.

If I use your idea I could connect the WiiM to Tape 2 instead AUX 1 but how to switch with wich selection to listen to phono or stream?
And does it mean that I can use the EQ for my phono, right?
Are you sure your headphone amp is connected to "tape 1
in"? That would be an
input, it couldn't send any
output to the amp. I'm assuming it's actually connected to "tape 1 out". I also assume your speakers are connected to the "system 1" outputs. If not, just replace "speakers 1" with "speakers 2" in the following sections.
General setup
Connect your WiiM Pro Plus' line out to "tape 2 in" instead of "aux 1". If you wan't to be able to apply the WiiM's EQ to the turntable input, also connect "tape 2 out" to the line input of the Pro Plus. Don't use the "source direct" button whenever you have set the rec selctor to anything but "off", as "source direct" will disable the tape outputs.
Case 1, streaming sources to speakers
Enable speakers 1. Play something on the WiiM and press the "tape 2" button. The position of the input selector on the Marantz shouldn't matter. Set the rec selector to "off", so the WiiM Pro Plus doesn't try to auto-sense what's fed into it's line input.
Case 2, Dual turntable directly to speakers (no EQ)
Enable speakers 1. Set the input selector to "phono" (as before) and do
not push any of the two tape buttons. The position of the rec selector doesn't really matter, but setting it to "off" will ensure that no output is sent to either the headphone amp or the Pro Plus.
Case 3, Dual turntable to speakers with WiiM EQ
Enable speakers 1. Leave the input selector in the "phono" position, but set the rec selector to "source"
and press the tape 2 button. On your WiiM Pro Plus select the line-input if auto-sense doesn't do so anyway.
Case 4, streaming sources to headphones
Disable speakers 1 and 2. Play your streaming content on the Pro Plus and set the rec selector to "2->1 tape copy". This will direct the WiiM's line output (connected to tape 2 in) to tape 1 out. The position of the source selector doesn't matter. Caveat: If you have applied the WiiM room correction for use with your speakers you will have to disable it manually on the Pro Plus.
Case 5, Dual turntable to headphones (no EQ)
Disable speakers 1 and 2. Set the source selector to "phono" and the rec selector to "source", justs as before. The phono signal will also be send to the WiiM's line input, so it may wake up from standby if you have auto-sensing enable for the line input.
Case 6, Dual turntable to headphones with WiiM EQ
Disable speakers 1 and 2. Set the source selector to "phono". As mentioned before, the phono signal will be send to the WiiM's line in. Select the line-input if auto-sensing doesn't do it. The WiiM Pro Plus output is fed into "tape 2 in", so again set the rec selector to "2->1 tape copy" to direct this signal to your headphone amp.
Warning! No, I did
not test this, of course. It all just stems from my understanding of how your amp should work to the best of my knoweldge. If something happens to not work out ... well, my advice comes with no warranty.
I hope my explanation makes some sense to you and doesn't come across as as bunch of random rules.
