In my opinion the dollar per watt (every amp is underated) and features offered, along with the rediculously great CS was the main selling factor for myself. Do you think you could speak with the owner of any mainstream company in any capacity? I felt like Jacob truly cared about every product he put out along with every customer he has. Sundown stands behind every product they have. I haven"t seen one person on any forum that has had a problem (even if user error) that hasn't got something done to remedy the problem by Sundown. Once again, this is my opinion.
