Hi I have always loved the old shape/design of the older Quad ESL 57's, and am on a nervous point about to possibly buy a clean/used pair from ebay. The only thing is, I have NEVER heard a pair of 57's, I have been using a brilliant pair of Magneplanar 0.6 speakers for the past 8yrs with awesome results, yes, I love panels ok! Any advice/thoughts would be appreciated from any owners out there please... I presently use valve amps, Primaluna Prologue 7, 70 watts, using standard KT 88's, marvellous sound. Are the Quad 22 power amp's the standard match for Quad 57's..? Thanks in advance! peter (Ireland)
