In Grey's original schematic, he used a 2 amp bias current per side (a little over), and stated that it would just about double power into 4 ohms. So, 74watts into 4 ohms comes out to be about 4.3 Amps, right? So, I then assume that the bias current per side is one half the total bias required by the minimum load. Is this right?

Now, I may be way off here, but I assume that this bias is required because the Alephs are able to output 2X the idle current to the load because of the variable current source (as mentioned in the zen variations part 2). If we were building them with convential current sources, would this current then need to be doubled to get the same output?

Sorry for being redundant in posting yet another thread on this topic, but I wanted to get this cleared up once and for all.

Thanks.
