@ Andy Peters: No, I didn't ignore it, I just replied to it. Yes, you are right that the buffers can have a smaller capacity, but as this is an UNREGULATED design, they still have to be adequate. But they are not. They are adequate if you have nearly perfect main lines with low impedance, a.k.a. virtually NO voltage drop on huge current demands. You have that many times, yes, and with big big events you have it 80% of time, so this problem is reasonable to ignore. But for the smaller companies with 'wall outlet jobs', fulfilling their dream to have such an amp, this would be a massive drawback, but yet they'd have to admit that their hard earned bucks went into a product not fully up to what they thought. Most people just can't do that and it's the subconscience doing this. They don't even intend to....
Still, even with good power lines, there are amps with less power rating outperforming the Vortex in bass range. Believe it or not.
All you Vortex owner might feel insulted by my statements. If you are really FULLY happy with them, so be it, but I think potential new customers have the right to know that some people think otherwise.
A friend of mine, at least here in Germany known for his knowledge about amp circuit desgn, called the Vortex 'value engineered for high profits' (I hope I got that translation right).
@ John Roberts: Really, John, how many people do you know capable of admiting that they invested a big bag of money in the wrong product? As I said, it's already happening on subconscious level, the people can't do anything about it.
