Since I retired, I usually don't "plan" to do much of anything.
That being said, when it comes to my audio system, two things that recently became top of mind are fixing my room acoustics and buying new speakers.
I am pretty handy, so the room acoustics are a fun DIY project, but because brand new speakers are not in the budget now. That means that I will keep my eyes open, keep reading this forum and selected reviews and hope I can find something on the used market.
