As you said, it’s a adventure! I don’t know if anything is ‘forever’ in this crazy hobby, but I do see myself living with my Tannoy Canterbury’s for a very long time. Once they are in your possession, you may realize that they are built to very high standards and worth every penny to hoard them in your permanent collection :-)

Wow, my room wants to be your room when it grows up! Those Canterburys must throw an incredible soundstage in that space, with lifelike dynamics, to boot. I'm hoping to start building a house in a few years. I've got a listening room in the drawings. For now, it's the living room.
I'll be using REL subs with my Stirlings, as well. A pair of T9i, in my case. REL seems to have the reputation of being able to pair well with most anything, so they seemed like the right choice for somebody like me. :) They've been working well with my Lintons.
My electronics are SS McIntosh, fed from Qobuz (via Roon) and a Michell Gyrodec SE.
