The 700 wpc for stereo applies to 15A circuits. A1400-8 is capable of even more power delivery when connected to a 20A circuit according to a very reliable source. Whether you would ever need to run your mains at that power for any length of time is another issue. Whether you end up getting the A1400-2 or the A1400-8, you will surely get superb customer service from Axiom.
