High Sensitivity Speakers that work best with SS

The 16 ohm load would be an easier load to drive for the OTL amplifier thus it's operating more efficiently would be my guess.

I wonder whether this is why Lou likes the Modwright KWA150Se with his speakers--it delivers the first few watts in Class A before switching over to Class A/B operation. Given the load presented I wonder if the KWA ever leaves Class A when paired with Lou's speakers. This may have something to do with the synergy between Lou and Dan's designs.

Class A works well with an A class design :)

Unsound, no need for "with all due respect", my comment was certainly not meant as a definitive explanation. (I am in no way qualified to do that, I'm a theoretical physicist/spectroscopiest.) However, I am not saying that subsequent watts compromise the first watt, but rather I am wondering whether the designers of powerful ss amps (e.g. 100 - 200 or more watts into 8 ohms) pay always attention to get the first watt right. It is common sense to expect that an apparatus may not necessarily performed optimally when operating at only 0.01 - 0.1 percent of its capacity. Even the smallest perturbation may be significant in that situation.

I hope Atmasphere (or somebody else) can clarify this question of mine.

NVP, I would suspect that an amp working close to it's maximum capabilities might not necessarily perform optimally. Many high powered amps are biased at the low end towards Class A shifting towards Class AB as the power needs increase, avoiding the onset of clipping.
