Oooh, great thread!
My Beosystem 3500 has been my “daily driver” for nearly two decades and I love it! I can’t see that ever leaving (I already have a stock of replacement parts ready “just in case”!)
If I can ever find a really nice 1970s Beocenter 3300 then I would also keep that, as I had one as a teenager and have always wanted another one.
I also suspect that Penta mk.3 will always have to feature in my life unless B&O can come up with a modern replacement…
Kind regards, Steve.
