Do you have the original
103, or the 103.2 (
which came out in 1980)? I have heard great things about the 103.2, and imagine that the 103 is a fine speaker as well.
From looking at old information about KEF speakers from that era, I know why I did not buy any at the time, as they were rather expensive (one must remember inflation and what a dollar was worth back then when thinking about such matters; I also had far less money at my disposal then). But from my little experience with old KEF speakers now, it was money spent for quality.
