Welcome to the insane asylum! (kidding)
Lot’s of good advice here but no questions about what kind of music you like and at what volume?
The reason I ask, is that your musical preferences can and should inform your speaker/amp choices.
One of the reasons I went with Harbeth is they are designed to sound very good at low levels, and do IMO. But even the 40’s aren’t the best rock speakers.
Just an example - not trying to sell you on Harbeth at all.
Good luck and enjoy the ride.
