Any comments on the relative merits of various opamps
and opamp spec. figures for audio preamp and filter applications
would be welcome. Which figures are relevant for, say, phono
preamps, but not so much for tone control (no ultra-purist flames, please)
filters and vice versa?
Has anyone experimented with something expensive like, say, the
OP-27, and found audible improvements over the 1458, 4558, 5532 or
5534? How about the encapsulated discrete modules that you sometimes
see advertised in recording engineering trade magazines - hype or quality?
Are all of these poor choices when compared to an optimized discrete design?
