The main thing is to buy what you like and what you enjoy to listen to. There is no such thing as a perfect system and it is very subjective too.
As a retirement present to myself, I bought myself a simple and non clutter system because I no longer want to have multiple components and cables running among them. I purchased the Devialet 1000 Pro with a pair of Focal Maestro to simplify my home. The source is a custom built cube PC by my son-in-law with two dedicated 6TB hard drives with Tidal / JRiver as digital music management. I will later re-condition my 40-year old turntable as analogue source and same vintage NAD CD player for my CD collections.
