I’ve been wondering about Pass Labs amplifiers and stability at low resistance. I have the Xa 100.8. I often see that some amplifiers double power output as the as the impedance halves. I also hear about amplifiers being stable at lower impedance e.g 2 ohm and even 1ohm. My speakers dip to less than 2 ohms impedance and I wonder whether my Xa 100.8 is stable at that load and what is the output power at that load.
