The old Phoenix Gold "M" series amps kicked ass if you had lots of speakers to drive, and wanted less than .5%THD at .5 ohms.
PPI still has killer bang for the buck. The A600 and A1200 could either drive 2 15's or 2 18's to about 135db.
But for true, output for the $. I'll take the MTX Pro series.....not a lot of cash, but absloutely bullet proof. I have the Pro 1502 driving 3 10's and it is sweet, tight, and powerful all at the right times. It used to power 2 JL Audio 12w6's and it still sounded great for the price.
BUT if you are gonna be on a spectrum analyzer for a comp, then go McIntosh or Xtant, or a/d/s. Otherwise, your ears aren't gonna hear a lot of difference.
