XINDAK MS-3

Pre owned. In good conditions. Shows light signs of wear. Without original packaging included.

The Xindak MS-3 are KT-88 tube monoblock power amplifiers delivering 60 watts per channel. They are designed for the discerning listener who seeks the warm, engaging, and silky sound characteristic of tubes, with a multi-chassis configuration that carefully separates the different sections. Each mono channel uses an ECC83 (12AX7) tube in the preliminary amplification stage, while an ECC81 (12AT7) handles phase inversion in the push-pull circuit built with a pair of KT88 (6550) tubes. A 5Z3P (5U4G) tube serves as the rectifier, ensuring stable and clean current.

The output transformer is of the EI type, engineered to provide a wide frequency response, while the power supply section uses a toroidal transformer to minimize external interference. Rubycon capacitors filter the input current, while the amplification stage employs red WIMA capacitors and precision axial resistors, enhancing signal linearity and purity.

The Xindak MS-3 stands out for its transparency, delicacy, and fluidity, reproducing every musical detail naturally without fatiguing the listener. Its high power allows it to drive even medium-to-low efficiency speakers with ease, making these monoblocks ideal for high-end hi-fi systems that demand both engaging and refined sound performance.
