Ozzy,
I agree with your perspective but interestingly it was Dave Wilson himself who intentionally demonstrated his Alexia driven by a receiver. Seems odd given the known load characteristics of this speaker. Who’d be more aware of this than the designer/builder himself? Perhaps this receiver was particularly robust. It seems Wilson was trying to make the point that amplification is not that important. This goes against my experiences, amplifier quality/capability most certainly matters.
