[QUOTE][i]Originally posted by Decca [/i] [B]I would also consider DNM or Sugden. Concordant made some superb amps, it is a shame Mr Dunlop is no longer alive. I have an old Concordant lying around somewhere, anyone know what they are worth? [/B][/QUOTE] Not too much I don't think. Not many people know about them. Of course Doug Dunlop used my [i]System IV[/i] as reference speakers to develop them. Actually I've also got a couple of Sugden C51s (preamps) if anyone cares.
