Hmmm, I think you're right, Chebby. It was an 'off the cuff' remark, to which I gave insufficient thought. I was probably out by about 5 years.
Although I did have 'radiogram' type stuff long ago, mostly sourced from second hand sales of one sort and another, my first serious hifi was a Quad II / 22 set initially with big flat panel Wharfedale speakers. I soon progressed to Quad 33 / 303 and briefly tried ESL57s although they were too big. So, I bought LS3/5a speakers. It all seems so long ago, nowadays.
I think you're probably also right about the ESL 57 "run for the money" remark, and I never did like metal tweeters in most applications.
