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 mid-period type of the DCD-1650SR, the condition is also good. For this listing, the pickup lens has been replaced, and silicone grease has been applied to the sliding parts. The tray opening/closing rubber belt, rocker switch, and overcurrent protection element, which are common causes of repeated tray opening and closing, have 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 to be problem-free for both channels via RCA for analog and OPTICAL for digital. There is no crackling in the PHONES output. Included accessories: * Generic power cord * Replacement remote control RC-253 (batteries not included). The volume button, which is not present on the RC-281, cannot be used. * Instruction manual (copy) This is a used item of age, so it is not new.
