Georgehifi,
Here is the difference between me and you. Your posts are all conjecture and hand-waving. Conjecture and hand waving is ..... well just that.
Again, let's look at facts:

Again, let's look at facts:
- 1500 watts into 2 ohms is 27 amps
- 100 watts into 2 ohms is 7 amps
- Maximum dissipation in a LINEAR amplifier with a real speaker load DOES NOT happen at the spot on the speaker impedance curve where the current delivery is highest.
- Class-D is not impacted by phase w.r.t. power delivery in the same way a linear amplifier is, either in device dissipation or power supply loading.
- Other than knowing an amplifier can deliver 100 watts into 2 ohms, you have no data that shows the power supply is any more capable of supporting continuous additional power delivery and the dissipation peak of the speaker load
- You have not heard the Alexia with the Behringer, but you are making many claims that you don't have the requisite data to support.
- You are deflecting bringing up OTL amplifiers
- There are many reasons why power may not double with every 1/2ing of the impedance, and without knowing what that reason is, you can't made factual conclusions about an amplifier beyond that it will clip at a given wattage and load impedance (as stated in the specs). If the 2 ohm wattage is stated (and distortion components), and given that impedance doesn't drop below 2 ohms for almost all speakers, then beyond knowing where clipping will occur for 2 amplifiers, you really don't know much else. Any other conclusion you arrive at is purely assumption.
