I don't mean to sound picayune, but I would once again call attention to the first of my posts dated 5-5-13 in this thread, dealing with terminology. IMO the terms "voltage amp" and "current amp" are incorrect and misleading.
A "voltage amp" would be one that amplifies voltage. A "current amp" would be one that amplifies current. But all or nearly all amplifiers amplify both. What is really being referred to are amps that act as voltage sources, and amps that act as current sources. But that isn't right either, in most cases, because most of the amps that are being referred to as acting as current sources only act in that manner to an extremely loose approximation.
What would be better, IMO, is to refer to amps that have negligibly small output impedance (i.e., most solid state amps) and amps having significant output impedance (i.e., most tube amps and a few solid state amps). Or, alternatively, using Atmasphere's terminology, amps conforming to the "voltage paradigm" and amps conforming to the "power paradigm."
