MoonDrop DISCDREAM 2 Ultra Portable CD Player

DISCDREAM 2 Ultra Portable CD Player The first-generation products of the DISCDREAM series combine and match the existing circuits of different eras. It's required by modern measuring instruments and past listening standards. It's highly anticipated due to its audio performance; however, production is limited due to the difficult workmanship. In the past year, we have tried to continue production while upgrading and developing the audio circuit of the portable CD player. After more than a year of development, we are proud to present the brand-new second-generation product of the DISCDREAM series. All-Aluminum Alloy CNC Finishing with Hi-End Technology and Texture: Classic Portable Clamshell Design The DISCDREAM 2 Ultra features a portable clamshell design that minimizes potential damage during disc placement, making it ideal for on-the-go use. Crafted from high-precision CNC-cut aviation-grade aluminum alloy, it boasts a meticulously polished surface and a textured finish, delivering a sleek and premium aesthetic. Professional Audio CD Player with Advanced Servo Architecture The DISCDREAM series sets a new standard for portable hi-fi CD players with its professional CD servo architecture, ensuring exceptional performance and reliability: Motor Drive: Equipped with imported high-quality audio driver chips for stable and consistent speed. Optical Assembly: Features a professional-grade CD laser head, delivering outstanding disc-reading capabilities. Double Shock Absorption: Combines an electronic data buffer circuit with an elastic-damping physical buffer to minimize the impact of vibrations on CD playback. Professional Hi-Fi Audio Circuit with Fully-Balanced DAC Decoding and Amplifier Output The DISCDREAM 2 Ultra merges modern technology with a tribute to classic designs, delivering unparalleled audio performance: Premium DAC Decoding: At the heart of its digital audio prowess are dual Cirrus Logic flagship 32-bit MasterHIFI audio decoding chips, enabling fully balanced four-channel high-quality analog signal output. Hi-Fi Amplifier Circuit: An independent, fully balanced amplifier circuit ensures ample, low-distortion power for driving headphones via the 4.4mm interface. Electricity: The Mother of Sound: Seven linear voltage stabilizing chips independently supply power, enhancing hardware-level performance for superior sound fidelity. The DISCDREAM 2 Ultra not only pays homage to the classics but also redefines them, setting a new benchmark in portable hi-fi audio. Hi-Fi Audio-Grade Materials for an Exceptional Listening Experience The DISCDREAM 2 Ultra is meticulously crafted with premium materials to elevate your audio experience. It features a full set of Ruby automotive-grade aluminum electrolytic capacitors, known for their reliability and superior audio performance. Three high-precision NDK audio-grade crystal oscillators are used for accurate clock control, ensuring exceptional sound clarity. Tuned by experienced audio electronics engineers, it delivers a warm, delicate, and clean sound signature. Every detail reflects the commitment to achieving unmatched audio quality and a refined listening experience. 4.4mm Fully Balanced Ultra-low Distortion Headphone Output DISCDREAM 2 Ultra features two output interfaces for driving headphones: The 4.4mm interface provides fully balanced output commonly used in modern HiFi players, delivering 4Vrms/222mW undistorted output power under a 32Ω load. It can easily drive most in-ear headphones/earbuds as well as high-impedance full-size headphones, including some planar headphones. The 3.5mm interface offers standard stereo output with a 2Vrms output, suitable for driving most in-ear headphones/earbuds. Undistorted output power In accordance with clause 6.4 of the AES17 standard, the maximum output, prior to 3dB compression, of 1% THD+N or 0, represents the maximum undistorted output power, whichever is reached first. This criterion helps differentiate it from the maximum output power, and it is the genuinely effective output power for users. Additional 3.5mm Multi-Function Interface The DISCDREAM 2 Ultra is equipped with a versatile 3.5mm multifunctional interface that supports both digital optical and analog linear output. This allows it to function as an all-around player, seamlessly connecting to amplifiers or active speakers. Users can utilize the analog linear output to connect active speakers or pair it with an external pure amp or power amplifier for driving high-demand headphones. The digital optical output adds further flexibility, enabling connections with DAC/AMPs, speaker systems, or other compatible devices. This multifunctional interface enhances the DISCDREAM 2 Ultra's versatility and usability in diverse audio setups. Not Only a Portable CD Player, but Also a USB Desktop Sound Card The DISCDREAM 2 Ultra offers dual functionality, serving as both a portable hi-fi CD player and a desktop USB sound card: Hi-Res Audio Support: Supports PCM decoding up to 32Bits/384kHz and DSD256 for high-resolution audio playback when used as a USB sound card. Plug-and-Play Compatibility: Works seamlessly with Windows and Mac OS without requiring additional drivers, ensuring a hassle-free setup. Versatile Usage: Perfect for portable on-the-go listening or as a high-quality desktop audio solution.
