For securing the power transformer, a transformer base that floats with resin in a cast trunk case, common with the higher-end model DCD-S10IIIL, is used to cut low-frequency noise (Image 14). Equipped with AL24 Processing technology, it uses a Burr-Brown 24-bit DAC (PCM1704), making it a popular model with a focus on sound quality. As this is a later type of DCD-1650SR, the condition is also good. The original selling price was 120,000 yen (excluding tax). For the listing, the pickup lens has been replaced, and silicone grease has been applied to the sliding parts. The tray opening/closing rubber belt has also been replaced. As there are cases where the DAC on the L channel often fails due to its own heat generation in the DCD-1650SR, heat sinks have been attached to both channel DACs (Images 15 ⇒ 16). The overcurrent protection element in the power supply has also been replaced. In addition, low-viscosity high-grade oil has been applied to the oil-impregnated bearings. Playback has been confirmed to be working without any problems for both channels, analog via RCA and digital via OPTICAL. There is no crackling in the PHONES output.
