Dear @lewm : I had a rare opportunity to listen the First Watt and XA NP designs in the same system with Magico speakers.
Differences are not nigth and day in favor the XA amplifiers but way notorious. First Watt is a " so so " amplifier and nothing more where the XA is in a different " world " at quality performance levels.
Personal preferences dictates each one audio items judgements.
Anywat NP electronic designs are very good and competitive. I remember the very old Threshold S 5000E and the SA-1 when in those times NP preference belongs to bipolar devices instead today MosFets or Jfets. I'm with bipolars as output devices but at the input too and I don't like transformers at the input as in the SIT FW amplifier. Well there is no perfect electronic designs, trade-offs always exist.
