I use Sennheiser HD650 headphones driven by an old NAD integrated amp (#3130 - 30amps). What $ amount should I expect to spend for a significant improvement in performance? Any product suggestions? Any opinions about the value of crossfeed technology (i.e. Grace Design or Headroom amps) or about the use of balanced vs unbalanced outputs? Thanks, gkus
