I wanted to upgrade to arc from playbar taking advantage of the 30% discount and being able to sell playbar for £200.... Expensive hobby but WOW atmos is immense.
Luckily was able to use my sub and 2 play 1s after a bit of faffing updating them, but play 5 was gen1, as was my zone player which linked my rega turntable. Sold both already!
Also upgraded to the port (managed to bag a new one/unused off ebay for £200) and bought an ikea bookshelf speaker - really is a decent bit of kit for not a lot of money - £115 posted.
I'd recommend an upgrade to arc and replacing other speakers with ikea.
However the system did drop once already. Hoping that doesn't happen frequently. Restarted phone and it resolved itself.
