In the latter half of this thread, moderators defend the right of posters to undermine the reputation of the latest design from this outspoken opponent of subjectivism, based only on unsupported subjective opinion. Well-known designers and respected analog 'gurus' lend their tacit support by participating in the thread.

Now I want to try this preamp! I'm not big on the whole preamp thing in general, but hey, if it pisses off subjectivists...

I have a copy of "Self On Audio" second edition, which contains the 1996 preamp articles. The genius of the preamp is IMO not any special innovations, but rather the careful and clear way that Self explains how he optimized a pretty common and straight forward design. Basically, he's exploiting the fact that the now sub- 50-cent 5532/5534 op amp chips are really very, very good.

By now the chip design has to be more than 30 years old, but it still shows up in new equipment designs. In the day, many of us merged these chips with the most recent wisdom from Vanderkooy and Lipshitz about RIAA networks and pretty well cook-booked our ways into our last phono preamps. Nothing ever emerged that sounded better for use with MM cartridges, to this day.
