RE: OP Amps, Whats Your Opinion?

"phonopre is the most simple amp there is,"

A phono preamp that is well designed is the MOST difficult amplifier to engineer. Anyone can put together a simple filter with a 6dB/ octave slope, however that filter would not be close to the the RIAA curve. Further, it takes a real engineer design a circuit that is consistent in manufacturing and that does not degrade as the components age. Many in the DIY community build all sorts of power amps and preamps before tackling a phono stage. Anyone who believes that it is simple doesn't understand the process or the engineering.
