I do plan to keep my Reference 75SE for much longer than I had originally planned. I'd thought about eventually making the move to the 160s, but now I can't imagine replacing the 75SE. Before I purchased, I asked one of my local audio club members who's had the 75SE, the VT-80 and currently has the 160s about it and his comment was the 75SE will go down as a "Classic". I couldn't agree more.
