Product Description
The Esoteric E1 phonostage, as part of their Grandioso range, truly embodies a renaissance in vinyl playback. We encourage you to read the full specifications at the Esoteric site, as there's a lot to take in! We can't think of a more technically advanced phono stage in every possible way. https://www.esoteric.jp/en/product/e1/feature
The E1 phono stage preamplifier reveals the true sound of the MC cartridge with its unique balanced current input. The Grandioso E1 is equipped with three Esoteric original MC balanced current inputs (XLR), which accept the “current” generated by the MC cartridge as a balanced signal. It is not widely known that the output current of MC cartridges is significantly higher than that of MM cartridges. The MC balanced current input is the most efficient and lossless way to extract the full energy generated by the MC cartridge, compared to the conventional “voltage input,” which converts the output current to a “significantly low” micro-voltage via a load resistor. This approach allows the sound inherent in the MC cartridge to be reproduced with all the performance’s reality intact. Additionally, there is no need to worry about impedance matching between the MC cartridge and the phono stage, ensuring that the best sound can always be extracted from the MC cartridge.
Optical cartridge input: Optical pickup cartridges use an internal LED and a light receiver (PD: photodiode) to optically detect the movement of the cantilever and output it as an analog music signal. The E1 is equipped with a pair of RCA input sockets dedicated to optical cartridges. Since optical cartridges require completely different amplification and equalization methods compared to MM/MC cartridges, the E1 includes an independent, dedicated, fully balanced/dual mono phono stage preamplifier. This unique balanced/dual mono phono stage preamp circuit with an external power supply, discrete low-feedback power regulator, allows you to enjoy the crisp sound of an optical cartridge at the highest possible quality.
