While I respect HiFi Guy's experience and knowledge, I do disagree about powered speakers. For a first set-up, they can be a viable alternative to separates. I don't find it to be anymore "starting over" than having to sell another component to upgrade, but it does represent a different upgrade path than separates. I used to disdain powered speakers, but over the past few years I have heard good examples and they do save space and money in tight situations.
My systems are all separates, mostly because I'm old-school and I have grown disposable income and space over time. For people in different circumstances, there could be different choices that are better for them. Also, in full disclosure, I used a NAD preamp for more than 25 years before upgrading to a Bryston integrated in 2020. I kept the preamp, but upgraded speakers, power amps, turntables, and phono stages along the way. In this TTL set-up, the long term keeper is likely to be the turntable versus the speakers or phono stage.
