I remember back 25-30 years ago when slew rate became the big buzzword among audiophiles. I read 'The Audio Amateur' at the time, and Walt Jung was a contributing author, writing many articles for the magazine. I believe it was Walt who finally got to the bottom of the slew rate debate, and did an article called something like 'Slew Rate- How much is Enough'. The bottom line was that any device, whether it be a preamp or power amp, needed to slew 0.5v/us for every peak volt output, in order to avoid SID (Slew Induced Distortion).
You are certainly right about too many products being sold based on specifications. The prey on the uninformed. Everything is a balance, and good engineering carefully weighs all sides.
