@boomerbillione As pointed out above, your statement about Pass Labs amplifiers is simply not true. Not only does the xa25 double output power from 8 to 4 ohms, but so does *every other amp they make*.
There are a few First Watt products that put out less power into lower impedances (http://www.firstwatt.com/prod.html) but obviously those are built for special cases where the end user does not need high power and has carefully considered the speaker/amplifier match.
