■ Price not negotiable ★ This is an improved model that disregards the cost of the mass-produced unit and uses expensive parts extensively to achieve higher sound quality and reduce the failure rate. ・ 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 measured, and selected parts were used. ・ Replacing parts alone can cause unnecessary load and operational instability due to electrical characteristics, so the replacement was carried out while sequentially inspecting the characteristics. ■ Effects An actual listening test was conducted with the original unit. 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 the breath of the vocals. ・ The high frequencies have noticeably increased resolution, and the sharpness and decay of attack sounds like snares and toms are beautiful. Even those who are not very interested in audio will definitely notice the difference. ■ The following work has been done to ensure longevity ・ 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 confirmed ・ 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 ・ Other multiple ■ Appearance ・ Please note that there are scratches on the top surface. ■ Shipping contents ・ Main unit ・ Main unit & BT instruction manual (printed) ・ Power cord (compatible) ・ Remote control (compatible) ・ Removed parts ■ Warranty Complete free support for any problems that occur within one month of arrival. 【4546】 #Bose #wave #music #system #Fully functional #wms #awrccc #awrccb
