For securing the power transformer, a transformer base that floats in resin within a cast iron trunk case, common to the higher-end DCD-S10IIIL model, is used to cut low-frequency noise (see 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 a mid-production type of the DCD-1650SR, it has minor scratches, but is in good condition. For this listing, as shown in image 17, the pickup lens was replaced as a unit, and to prevent the tray from repeatedly opening and closing, which is common with age, the rocker switch, overcurrent protection element, and rubber belt were replaced. Additionally, a heat sink (images 15 ⇒ 16) was installed on the DAC, which is prone to failure due to its own heat generation. Playback was confirmed with no issues on both channels via RCA for analog output and OPTICAL for digital output. There is no crackling in the PHONES output. Included accessories: * Generic power cord * Replacement remote control RC-253 (batteries not included). The volume buttons, which are not present on the RC-281, cannot be used. * Instruction manual (copy) This is a used item of considerable age and is not new. Please refrain from considering this item if you are concerned about minor details.
