I would go with the monoblocks with the shortest speaker cables I can find. Get them used. They drop in value. Pass is great. Had an x350.5 but I sold and bought it for 5400 three years ago. I haven't seen one under 7500 for a long time.
Pass Labs 350.5 or Parasound Halco JC1 Monoblocks
Has anyone had the chance to compare the two?
