My first real speakers were Small Advents, they were great for 1974, boomy and unsettled foggy bass, but bass. I moved up to cleaner speakers when I got a real job, I can't recall the name, and when I retired got some Monitor Acoustics Silvers, which are solid, added a MA sound bar and subwoofer. I had a half decent Onkyo receiver that I upgraded recently and was shocked at the difference it made. I got a "refurbished" Yamaha receiver that was obviously brand new anyway.
And now I rarely listen anyway.
My buddy in Cincy told me he spent over $2 K on speaker CABLES alone. He did have a nice system, three of them actually.
We bought a Yamaha "electric piano" that is awesome, it uses a normal keyboard and translates that into electronics. So, the action feels like a real grand.
The wife uses it as a stereo in the bedroom. She listens to classical almost nonstop.
