I can answer part of the question but I cannot corelate it to the technical description from the article. I bought soulnote sa710 amplifier approx. seven years ago. Currently the amp is paired with KEF LS50s.
I have attended live concerts at the Village Vanguard and the Blue Note in NYC. My personal favourite are Patricia Barber concerts at the Green Mill in Chicago. When I listen to live music from these venues, specifically Jim Anderson recordings of Patricia Barber I am (almost) transported to those venues.
