Theta Digital Prometheus -
8 ohm - 250 W
4 ohm - 500 W
2 ohm - 850 W
Yes another one beside the Spectron (which is yet to be independently tested) that "can" get the watts up into 2ohms, but this is at a cost.
JA’s Note: " However, the distortion rises considerably into 2 ohms"
BTW: Note! Both use Linear power supplies that’s why they’re big/heavy for a Class-D >20kg. No smp power supplies here, that’s a good thing.
