LUXMAN SQ-505X Integrated Amplifier with Wood Case Excellent Tested Japan GS03

  

Including & Condition Details: As shown in photos. LUXMAN SQ-505X Solid State Integrated Amplifier. The SQ series integrated amplifier was developed during the transition from vacuum tube amplifiers to transistor amplifiers. It has a mellow sound that you wouldn't expect from a transistor amplifier, and has a natural sound quality with a glossy mid-to-high range.

The power transistors used in this unit are a complementary pair of the legendary NEC 2SA627-2SD188, which was discontinued more than 25 years ago. In terms of sound quality evaluation, it is the only famous stone that can express a smooth, glossy, rich, and deep tone, with a great sense of the performer's presence in the sound field and the airiness and presence of the sound field, and the unique tone of the instrument itself, such as the sadness of the oboe, the transience of the violin, and the intensity of the trombone, is expressed very vividly.

It is the only famous stone that can produce a large contrast in the performance, from beautiful and delicate sounds to sounds that seem to resonate with the entire universe. Carefully performed and thorough maintenance. DC offset voltage (midpoint voltage) adjustment. The sliders of the volumes were rubbed and cleaned. The lever switches (8 units) had many poor contacts due to dirt and oxide coating, so they were disassembled, polished, and cleaned.

The selector switch and mode switch were removed, and the contacts were rubbed and cleaned. The tone control switch contacts were rubbed and cleaned. The PRE-MAIN switch slide switch contacts were rubbed and cleaned. The input RCA terminals were polished to a beautiful finish.

The front panel and knobs were polished and cleaned with ultra-fine particle compound to remove dirt. After maintenance, we checked the sound output by inputting records and CDs. The playback sound is clear, with a lingering sound from high to low frequencies, and the sparkle of LUX TONE. No scratching noise was felt when operating the volume or balance. The sound quality is smooth and smooth, which is hard to believe for a transistor amplifier. Since there is no protection relay circuit, slight noise may occur when the power is turned on/off. The wood case has small scratches due to aging.
