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 and using a Burr-Brown 24-bit DAC (PCM1704), this is a popular model with a focus on sound quality. As this is a later type of DCD-1650SR, the condition is also good. 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 side of the DCD-1650SR often breaks down due to its own heat generation, heat sinks have been attached to both channel DACs (Images 15 ⇒ 16). Low-viscosity high-grade oil has been applied to the oil-impregnated bearings. Playback has been confirmed without any problems for both channels, analog via RCA and digital via OPTICAL. There is no crackling in the PHONES output.
