Oh boy, I'm sorry to hear that. It looks like a nice place though. Anyway, we're all probably jealous that you live in Perth!
Obviously it's your money... enjoy it!
Perhaps go for the high end TT and amp and some good small speakers first (like other have said, get a 'feel' for the place). You could always exchange the speakers at a later date at the hi-fi store.
With a pair (or two) of good headphones you could relax in a nice armchair looking over the city with an adult beverage and cut out all that city noise around you?
Or perhaps some KEF LS50 II's with matching stands... that would give you streaming options too (perhaps you have no need for that)? And perhaps even add the matching sub in the future.
What kind of music are you into?
Variety of music, jazz, classical, pop/rock. Bob Dylan is a favourite, Pink Floyd, Amy Whitehouse, 60s...eclectic.
I will add streaming.
