implications of CI technology and how it transforms vinyl replay.
PHONO MCCI is a truly balanced, global feedback free, passively equalised moving coil phono pre-amplifier with the exceptional Current Injection input and LEF single ended class-A output stages.
The vinyl disc, dinosaur of music recording formats, only barely survived the CD. Today, however, the quality of turntables, tone-arms, and cartridges have increased to unprecedented levels, which vinyl recording producers support by pressing higher quality discs in limited quantities. This means new challenges as well as new opportunities for phono amplifiers.
The only consistent way to process the delicate music signal from a moving coil cartridge is with a balanced Current Injection (CI) input as the cartridge’s signal is among the most sensitive an audio amplifier circuit will encounter. Using CI, the current of the moving coil flows through the phono amplifier, including the first half of the RIAA equalization. The result is a level of dynamics, impact, spaciousness and richness of color that surpasses the performance of step-up transformers as well as the usual voltage inputs.
At the same time, Current Injection electrically damps the moving coil cartridge by letting energy flow into the CI input, instead of eliminating it in a cartridge load resistor. Transformed energy sounds different than and superior to eliminated energy.
B.M.C.’s use of distortion-free circuits with a Current Injection input and a Load-Effect Free output brings to listeners an advanced musical experience — exceptionally lifelike, open and natural.
