Many excellent and useful responses. I bought my first system in the mid 70's so I have been doing this for a few years. I have changed speakers five times since then. Analog source has changed twice and digital 6 times. My electronics (amp and pre amp) once from my first set up and multiple times with Herron Audio.
Just my two cents is to nail down the speakers first. This takes a lot of time and critical listening. You need to determine the flavor of the sound you enjoy as previously expressed. I would then focus on the source and electronics next. It can be one and done but you can probably guess that it usually doesn't happen this way depending on how long you plan on keeping the system.
If you are fortunate to have a good dealer network near you, this is the best way find the perfect match for you. If not, it will involve travel. Shows are a good source to get an idea of what you may like but I would never make a purchase based on a show. Good luck!
