I would recommend to start with the source. Though Speakers very in sound reproduction, dept, sound field, presents, bass, clarity and maximum power you will not have great sound without the clean Pre-amp / Power Amp. It sounds like you had very high end audio to start and I question why you sold it? The powerful Amp you had would work most anywhere. The speakers I can see because of ergonomics alone.
If it were me and you have the money invest I think you already know the market you will be in for cost and quality for the electronics.
Not Sure if you are thinking about space taken up by big amps so may I suggest an Anthem Integrated. There are many good ones out there to try out and they do not require a ton of room. A Blue Vault would be a good streamer and hard drive for playing. The speakers are a matter of what you like to hear in the music and I would ask the dealer (With promise not to cash the check for a few days) let you audition the speakers in you final room location with the furniture, decorations, (Drapes and such if there) and all you will have in the room. The room acoustics will be a factor and you want Speakers forgiving enough you are going to be happy with. I like to audition in the room at my place because it will be with your equipment. Hear it first at the dealer but do not give final payment until you know they perform in your setting. My 2 cents worth.
