★ This is an improved model that disregards the cost of the mass-produced machine and uses expensive parts extensively to achieve even higher sound quality and reduced failure rates. Bluetooth 5.1 is also built-in for easy high-quality sound. ・ Electrolytic capacitors in the audio signal circuit have been replaced with Rubicon film capacitors and Nichicon high-grade audio grade components (FG, KZ MUSE), which are more suitable for audio. ・ Power supply circuit capacitors have been replaced with higher-grade Nichicon capacitors than the original. ・ Electrolytic capacitors in the heat-generating parts of the control board have been replaced with Murata Manufacturing MLCC, which has a longer lifespan, lower internal resistance, and less loss. ・ Electrolytic capacitors in the control board signal circuit have been replaced with Nichicon high-grade audio grade components. ・ All of these components are several times more expensive than the original ones. ・ Before replacing the parts, the ESL and ESR of all capacitors were also measured, and selected products were used. ・ Replacing parts alone can lead to unnecessary loads and unstable operation due to electrical characteristics, so the replacement was carried out while sequentially inspecting the characteristics. ■ Effects A listening test was conducted with the original machine. The sound quality of the entire range has "significantly improved" to a level that is clearly noticeable. ・ The low frequencies have more tightness and definition, making them very pleasant. ・ The mid frequencies have more depth and luster, and even the breath of the vocals can be clearly felt. ・ The high frequencies have clearly increased resolution, and the sharpness and decay of attack sounds such as snares and toms are also beautiful. Even those who are not very interested in audio will definitely notice the difference. ■ The following work has been completed ・ Replacement of all electrolytic capacitors ・ Bluetooth sound pressure level adjustment ・ System update (Wide FM compatible) ・ Cleaning and greasing of the entire CD unit. Pickup & rubber belt replacement. Waveform inspection, output adjustment ・ All motor operation check (tracking motor replacement) ・ Spindle motor internal cleaning and lubrication ・ Cleaning and conductivity improvement treatment of all terminals and connector contacts ・ Power IC grease removal, thermal pad conversion & re-soldering ・ Exterior repair painting ・ GND insulation circuit added ・ Many others ■ Appearance ・ Exterior repair product. Please consider if you are concerned about the original color. Matte paint has been applied after a planar treatment with poor yield to improve the texture. ■ Shipping contents ・ Main unit ・ Main unit & BT instruction manual (printed) ・ Acrylic stand ・ Black power cord ・ Small remote control black (for WMS I) ・ Removed parts ■ Warranty Complete free support for any problems that occur within one month of arrival. 【4525】
