Info
Blue Robbie
The Blue Robbie is a Class-A discrete tube microphone and instrument preamplifier. With no ICs and the highest-quality discrete components from input to output, the Blue Robbie is one of the quietest (-131 dB EIN @ 50ohms) and most detailed (THD 0.006%) preamps. The Blue Robbie features audiophile-grade ultra low noise metal film resistors and polystyrene capacitors, and provides the user with the best of both worlds: an electronically-balanced, fully discrete input stage, tube gain stage (ECC88 twin triode), and an electronically-balanced solid-state output stage. There is no switching crossover distortion anywhere in the completely balanced audio signal path. And the Blue Robbie achieves 34dB headroom before clipping.
