The Kondo designed KSL-M7 preamps, represent the embodiment of the Audio Note Japan's design philosophy. The majority of the parts are Kondo designed and many, like the wire and coupling capacitors are hand made in Audio Note Japan's factory. Kondo's hand made silver-foil capacitors and braided silver ground wire. The pre-amp uses a 5687 x 2 for line stage. The output impedance of the KSL-M7 preamps are at approximately 600 Ohms, no feedback in linestage and Negative Feedback is employed only in equaliser section.
