It's old, it's tired, and it's still the best IC for building low noise audio circuits. It isn't just the low noise... The quality that makes the NE5534 ideal is the low noise combined with the huge gain*frequency product. The Bode plot for this device is amazing -- even today more than twenty years after Signetics dreamed it up.
