One of the absolute best systems I ever had was a Cary Audio SLP-98P pre-amp, BAT VK-60 and Usher AC-10 speakers.
They are big and very heavy speakers, but offer huge performance for their cost, especially on the used market.
I have moved on a 3 dozen times over. My need to change gear is pathologic. But that particular system combo was one of the few I could go back to and be happy with forever!
There are, of course, a ton of great speakers for that amp. But my experience with the AC-10 and the VK-60 was very memorable!
