EPDR does not impact Class-D amplifiers. I do not understand why you will not communicate what you used as a current probe to measure 80 amps peaks?

Generally I would expect an amplifier that costs literally 100 times more (per channel) than another amplifier to be "superior". However, your comment about "seriously current starved" cannot be backed up with facts. It does not go backwards into 2W, it has about 75% more power into 2W than it does into 4W. Do I have any illusions it can do 1500W into 2 ohms, even IEC bursts? Not really. But then again, you don't have proof it doesn't. I do know for a fact it puts out 75% more power into 2 ohms than it does into 4 ohms.

The Gryphon is a claimed 350W into 4 ohms continuous. The Behringer claims 750 (2x, not 17x). It also claims 3000W into 4 ohms. Will it? Doubt it, but maybe for IEC bursts. Will it do >1500W in long enough bursts to support real music at those levels? Yes it will, and yes, that is quite a bit more than the ~100 times more expensive Gryphon.

The primary limitation of it at 2 ohms, is the same as it is at 4 ohms, thermal, not current.
