Iggy- They don't need you. They have plenty of "lapdogs" that get excited about getting on waiting lists for months for untested products(ie.950)
Questions such as output devices...what kind,bipolar or jfet...matched?. What is in the signal path...capacitors? What is the power supply like? The damping factor may not mean much but it is much lower than any amp I've ever heard of with that kind of power. What does that mean? Like I said, if you are just adding a 6th or 7th channel then quality might not matter and people won't more specs.
