Hi Chris,
Truth of the matter is I can't remember what my 'heart's desire' was in those days. The only speakers I had heard at the time were some small Celestions (Ditton 15s, I think), Wharfedales (my speakers were DIY jobbies using Wharfedale DD-8RS drivers) and some small Tannoys (I think they were the model III LZ). Later I lived for a year with a pair of Lowther Acoustas using PM6 units, and for a time considered using the same drive units in the 'Lowther Ideal Baffle', with the option to build the Acousta cabinets later.
I don't think I had heard the Quad ESLs then (now, erroneously, referred to as the 57s).
Cambridge Audio later developed the R40 and R50 transmission line speaker. I did have frequent access to the R50s: a four-way design using the popular combination of KEF B139 woofer, B110 mid, Celestion HF1300 tweeter and STC (Coles) super-tweeter. I liked them, but when I heard the Quads they were what I was looking for.
I don't have the room for a complete Cambridge Audio system; the R50s are just too big and too heavy.
Regards
