@IanF Too many variables really.
Those in flats/apartments will have different needs to those living in the middle of nowhere - little point having the world's best system if you can barely ever raise the volume above voice levels.
Some folks want/need a dedicated "listening room". I don't have one of those (or a cinema room), so my system needs to fit around (and not unduly interfere with) my living room.
If it is
simply too much to ask that next time you are working, you make a quick detour via GLA, and come and have a quick listen
, then pop to a hi-fi shop with a listening room, and get them to demo something you can stream to with some half decent speakers and (unless you are like Jobbo) a sub.
Even Apple Music streams at 256kbs, which (imho) is plenty enough for you to hear the difference of a focussed system. Stick on a song that has real dynamic range (doesn't have to be modern stuff : Grace Jones - Slave To The Rhythm or Jill Scott - Gettin In The Way will do nicely - loads of others examples of course), and if it doesn't sound
enuff bettah - you have your answer, for you.
