Wait, the A07 should be max power of about 61W at 8R with the 48V brick supply (maybe a bit higher with the 48V you are using). So the preconditioning should be about 7.6W. So the problem is the manufacturer rating of 180-190W is bogus, probably at 10% distortion or just a plain lie.
edit: how much short-term power can you get it to do into 8R with your bench supply at 48V (now I notice the one Amir used was just 3A)?
