★ This is a modified model that achieves even higher sound quality by disregarding the cost of the mass-produced machine and using expensive parts extensively. Bluetooth 5.1 is also built-in, allowing you to easily enjoy high-quality sound. ■ Significant resources have been invested in maintenance, so a significant price reduction is difficult. ・ Electrolytic capacitors in the audio signal circuit have been replaced with Rubicon film capacitors, which are more suitable for audio, and Nichicon high-grade audio grade components (FG, KZ MUSE). ・ 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 have been replaced with parts that are many times more expensive than the original. ・ Before replacing the parts, the ESL and ESR of all capacitors were also measured, and selected products were used. ・ Simply replacing the parts can lead to unnecessary loads and operational instability 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 across 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 richness, and you can clearly feel even the breath of the vocals. ・ The high frequencies have noticeably 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 done to ensure long-lasting performance: ・ System update (compatible with Wide FM) ・ Cleaning and greasing of the entire CD unit. Rubber belt replacement. Waveform inspection and output adjustment using an oscilloscope. ・ All motor operation checks ・ Spindle motor internal cleaning and lubrication ・ Cleaning and conductivity improvement treatment of all terminals and connector contacts ・ Power IC grease removal, thermal pad replacement, and re-soldering ・ Voltage waveform inspection of the electrical circuits as appropriate ・ Replacement of deteriorated and easily damaged parts ・ Preventive replacement of failure-prone parts ・ Interior and exterior cleaning ・ Overall exterior glass coating ・ And more ■ Appearance ・ Color restoration completed. Maintenance is the same as for original painted and unpainted products. ■ Shipping Contents ・ Main unit ・ Main unit & BT instruction manual (printed) ・ White power cord ・ Small black remote control ・ Removed parts ■ Warranty Complete free support for any problems that occur within one month of arrival. 【4519】
