I wouldn't buy a 1.5 KW amp either, but for a different reason. Although I have a modern 220 volt drop to the house with ample capability, I do not have 220 volt service to the spare bedroom that I use for my shack. The KPA500 draws about as much current as I think it safe to run, given the 117 VAC wiring in that room. Before I bought the KPA500 I looked at the now-defunct Tokyo HyPower 1.2 KW amp, consulted with a professional electrician about what it would cost to run a 220 volt line into the shack, and decided against it. I suspect that 500 or 600 watts is a "sweet spot" in the market, given that at least some potential buyers would face the same issue I did. That makes the cost - not the price - of a 1.5 KW amp fairly steep. From a microeconomic perspective, I'll bet there's a knee in the demand curve somewhere over 500 watts and somewhere under 1 KW, the point at which a different AC service becomes necessary if not just prudent. That knee describes the probable
behavior of buyers and therefore a higher step in the market challenge for sellers.

I have no interest in a 1 or 1.5 KW Amp.
Guy (K2AV) sums it up nicely.
