“…if you want to hear the important musical detail presented in a coherent, clear-cut fashion this pairing has remarkably little competition in the two box arena. There are a few integrated amps which give them a run for their money in one respect or another but nothing comes to mind which seems like a better overall package.” Jason Kennedy, Hi Fi Plus No.75
