Kora Explorer 90SII CSC reference

The Explorer 90SII version is electronically identical to the 90SI, but offers an additional feature; the user can operate the Explorer as a preamplifier; also do Bi-amplification or connect a subwoofer. Mindful of your feedback, we have also added a universal remote control (volume on these models). Tube preamp: 12AT7EH The Explorer 90SII CSC version offers all the features mentioned above but with a significant particularity; indeed it benefits from CSC technology, correction of negative feedback, already acclaimed on our very high-end Galaxy and Cosmos models.
