Level matching my nuts lol, Take a 200watt Profile and a 200watt Orion for
say, crank the gain wide open and let me know if the **** sounds the same. How
many people do you know of that setup their amps with oscilloscopes? Most
people crank their amps for all that they are worth.

I thought we had already discussed this before. The most crucial ones are
level matching, double-blind testing using the appropriate statistical
measures, and assuring linearity during operation.
