Looking at the XTI2 series. Actually, bench testing two right now. What class is the design topology? They don't seem to get real hot at higher power. The loads do though!

Also, since no one is telling us what the parameters are for the "power ratings" on new amplifiers, under what conditions do these amplifiers meet the specifications?

These are Class AB+B except for the 6002, which is Class I.

The amps are tested for power capability with sine wave input and less than 1% THD.

Is there a link or how do I know the class of some crown amp?
