Ancient technology
I had an employer who insists his old tube-based amplifier is still superior to anything digital today. After hearing the quality at very high volume and very low wattage, I'm inclined to agree. Of course every few years he has to order new tubes from China or some eastern European country since there isn't much demand anymore in the west.
On the other hand, speakers have changed quite a bit over the years. There are even towers that you might not think capable of making any sound just by looking at them (google MartinLogan). Most people (myself included) still prefer a more traditional speaker for simplicity. When a simple speaker breaks, I know why and I can repair or replace it myself.
