It’s not tubes per se that HD6** and HD8** series need. It’s the impedance matching gutsy power of an Output Transformer-less (OTL) circuit. Like DarkVoice or Bottlehead Crack. They really do sound their best on OTL tube amps, as far as affordable options go. (Spendy other amps must be capable too.)
