Gah, sometimes audiophool jargon confuses the heck out of me.
Amp A from company X sounds neutral. Then when company X releases a new amp, amp B, it sounds even more neutral. Wat?
Amp C has Y power and amp D has 2Y power. Headphone H sounds much better on amp D and the only conclusion is because headphone H "scales up" and can "benefit" from the 2Y power that amp D offers.
Portable media player P has DAC 1 and amp 1. Portable media player Q has DAC 2 and amp 2. Portable media player Q sounds much better because of amp 2. Wat? Didn't these people go to elementary school and learn about the scientific method's 3 fundamental variables (controlled, manipulated, responding)? You can't compare P and Q and draw a conclusion that Q sounds better because of amp 2 when they're both different players all together. Ugh....people.
Replace the variables with names of people, and you've got society.
