A truly high current amp will double it's power everytime the impedence is cut in half. If you have an amp that has 400 watts at 8 ohms it should provide 800 watts at 4 ohms.
How to determine high current amplifiers
A couple of weeks ago I asked for recommendations on amplifiers to drive my Maggies 1.6Q. I was overwhelmed with all the amp recommendations. Although some differences in opinion on which would power the Maggies best - SS versus Tube - all seemed to agree that high current is more important than wattage. I am trying to narrow my list but I need to fully understand how to distinguish between low and high current amplifiers. What should I be looking for on the specification sheet that would denote high voltage?
