Gold is the only way to go. The diaphragm is normally open (behind a mesh grill) and not enclosed in metal like the electret which gives a much better open and clearer sound. Some of these mics can be powered on batteries, however they normally require a 9 volt battery to run or the full 48 volt phantom power.

The diaphragm in all higher end mics use a mylar material with a gold vapour coating. Gold is used for one major reason. It does not rust and the resistance of gold is fairly constant, unlike copper and silver which whilst they are better conductors, they rust and corrode which causes the performance to drop. The cheaper mics under $600 will normally have a cheaper plastic diaphragm with the gold splattered coating such as the $500-600 AKG C4000B. There are very subtle differences between the plastic and mylar materials which depending on your budget you may not consider worth the jump in price. There are only a few factories world wide that can produce a gold diaphragm so you quite often find that lots of mics share the same parts and sound and look very similar. Quite often the same factory produces both brands which is the case with this particular mic.
