Apart from the Last drop in Bolton, I regularly did the Harrogate show (I was a student in Leeds at the time, so 80-82).Harrogate, my stand out memory LP12/Quad amps/57's in the Quad room.
The year I went I was living in Harrogate so I think it would have been 79, definitely an LP12, don't know what the amps were. Being young I had no real experience of what would have been called higher end then, although I had seen an LP12 in hifi mags. I did manage to own a pair of Quad 57's, purchased a couple of years ago but swopped recently, loved them, but they were too large for the room.Apart from the Last drop in Bolton, I regularly did the Harrogate show (I was a student in Leeds at the time, so 80-82).
I remember meeting and chatting with Peter Walker, who was absolutely charming. My memory of the Quad ELS 57 speaker demos had a Walker t/t, not an LP12, but I do remember the 'live versus recorded' demo. The sound quality in that large room was superb. All very impressive to an impoverished student.
