I have to admit I didn’t read your entire post so maybe I missed something. But I glanced through it and saw your listed specs and your questions. You seem to have made the oppositions point for them IMHO.You asked about slew rate. About the easiest answer I can give is that it is the speed of the amp. It is a measure of its transient response. Think of it as "maximum rate of change of an amplifier's output voltage with respect to its input voltage".
A long book could be written about this subject and how transistor amps stack up against tube amps. But I will throw a drop of blood in these shark-infested waters and quickly depart. The following is a cut and paste from Wikipedia (so bite them not me).
"Because tubes are significantly more linear than transistors, tube amplifiers do not need as much global negative feedback to achieve acceptable linearity. While large amounts of global negative feedback are effective for reducing total harmonic distortion (THD) at low frequencies, feedback has downsides such as reduced stability, reduced slew rate, reduced bandwidth, increased high-order distortion [citation needed], and artifacts such as asymmetrical slewing [citation needed]. In most commercial designs, little attention is paid to these problems, and designers simply attempt to achieve the lowest possible THD."
