★ A compact size belies the sweet bass and expansive sound of this masterpiece. ★ Fully functional, with all electrolytic capacitors replaced, a common cause of failure. To avoid instability or malfunctions due to changes in electrical characteristics, we meticulously perform signal and waveform inspections, as well as operational checks (the parts used may vary depending on the individual electrical characteristics). ★ Furthermore, not only are parts replaced, but we use Nichicon's top-of-the-line audio grade MUSE capacitors wherever space allows. We also combine them with expensive film capacitors to achieve longer life and higher sound quality. This improved sound quality is effective for all audio sources, including radio, wireless terminal Pedestal, AUX, and headphone connections. ★ If you already own this unit, please compare the sound. You will notice the delicate sounds that were previously diminished due to signal loss and attenuation. While the WMS IV is known for its relatively powerful bass, this modification allows it to retain its strengths while also producing more delicate and vibrant tones. You'll notice enhanced snare drum resonance, the rich tones of the piano, the body of the guitar, and the lifelike vocals. The immersive sound of this unit, which is its hallmark, now feels even more vivid than before. This unit, having acquired a new sound, will continue to mature and deepen with aging. ◆ Maintenance Details ・All electrolytic capacitors replaced ・BT5.1 built-in & BT sound pressure level adjustment ・Amplifier section re-soldered ・CD mechanism unit cleaned and greased ・Drive rubber replaced ・Grease replaced with thermal pads ・All motor operation checked ・Spindle motor internal cleaning and lubrication ・Connector contact cleaning ・GND insulation circuit added ・Signal & waveform inspection of each circuit ・Many other items ■ Capacitors Used Nichicon: KW, UFW, KZ MUSE, LXJ, KMG Murata Manufacturing: GRM Kyocera: Tantalum capacitors Rubycon: Film capacitors ◆ Appearance Although in beautiful condition, it is not new. ◆ Shipping Contents ・Main unit ・Pedestal ・Remote control ・Instruction manual (printed) ・Power cord ・Replacement parts ・Acrylic stand Shipped via Yamato Transport 100 size. ◆ 1-Month Operation Guarantee We offer a completely free 1-month operation guarantee from the date of product arrival.
