Thanks for your response. In light of the excellent sound quality sfmorris described with the Luxman and Sony pairing, your explanation makes considerable sense. One can’t help but notice the contrast to what George and erik_squires concluded per citing the Stereophile review test measurement results of the Sony speakers. I can understand their respective responses given the test bench numbers.
Specifically the impedance behavior in the bass and lower midrange (Sub 3 ohm and steep phase angles) frequencies. You’d certainly predict the high current Accuphase to trounce the Luxman. This was far from the case. This has been a very insightful thread. Thank you sfmorris for sharing your very interesting listening experiences.
@atmosphere thank you for your informed comments as an experienced electrical engineer and manufacturer of highly regarded audio components.
