I have Harbeth P3ESR speakers and they are good. Very good for the price. But they cannot pretend to do justice to Led Zeppelin tonight. Is there anyone out there who has an informed opinion whether buying Focal Utopia Diablo at 5 times the price will solve that little issue ? But I want it all : acoustic jazz/ blues, classical... Think I am a little greedy ? Check the price ! Ampilfier is Leben valve 15 watt...
