If I upgrade my compatible speakers to S2, is it possible to then move them back to S1 (so they can be used again with my older units) or are they forever S2?
And is it a headache to switch them back? Ideally I’d like to be able to keep all my speakers on S1, and then on occasion use a few of them on S2 and then go back to S1. My guess is that won’t be an easy process.
