You can use cheap rotary switch to control a relay based input selector, so effectively have it both ways🙂
Just make sure that the thing that switches the actual signals has a contact material suitable for low-level signals, such as gold-plated contacts. Reed relays are also good, they don't oxidize because they are not subjected to oxygen.
Mercury wetted reed relays controlled by a low cost, non-shorting, 2 to 6 (user selectable) position, Lorlin rotary switch is the way to go.

6 Channel Unbalanced Stereo or Balanced Mono Audio Input Selector Relay Module | eBay
I use these. They have a 4 channel balanced version also.

Nice thing ! I have ordered one for evaluaton
BUT: i see one fault : it does not short unused inputs, thus bleeding through
will occur.. Have they turned the relays backwards this would not be a problem.
I don't think shorting unused inputs is a good idea. It will put an unnecessary stress on the outputs of the unselected sources. It would be interesting to see some measurements of the unused channels leakage though.
The outputs are only connected one at a time through the relays, If you want to switch the ground as well use the balanced version (or two boards).
