Five core design comprehensively upgraded the dm15 r2r represents a breakthrough, combining a smaller footprint with an even stronger feature set. Packed into its portable chassis are five core pillars the cd servo, usb dac, r2r module, and bluetooth module, all managed and coordinated by an mcu microcontroller unit. Such a thorough ldquocorerdquo evolution elevates the device in every way, surpassing the competition in its product category. Recreating analogue sound with distinctive characters custom fully differential true 24bit r2r resistor arrays dac in order to recapture the classic audio character of vintage portable cd players, the dm15 r2r is equipped with a proprietary four channel, fully differential 24bit r2r resistor arrays dac. It is built using a grand total of 192 precision thin film resistors 48 per channel, carefully selected for their 0.1% accuracy and low temperature drift 30ppm. The result is a nuanced, warm, and organic analogue sound. Custom cd mechanism reliable disk playback the dm13s disc reading performance has already seen substantial optimisation over the past year. The dm15 r2r continues to evolve upon this foundation, with further customisation of the cd mechanism. It features a self rebounding steel ball design for disc alignment, making disc insertion and removal smoother and less likely to scratch the disc. The disc reading capability of the dm15 r2r is comparable to the latest firmware version of the dm13. Due to the structural limitations of a portable cd mechanism, we cannot guarantee the perfect reading of all cds. We will continue to optimise disc reading performance through future firmware upgrades. Minor skipping when reading certain high capacity cds is normal due to variations in mechanisms, manufacturing materials, and recording conditions. Hifi grade usb dac exceptional decoding performance the highly anticipated usb dac function is now a reality. While guaranteeing excellent cd sound quality and compatibility, the dm15 r2r also incorporates a hifi grade usb dac. It supports high sampling rates up to 384khz 32bit and dsd256. Thanks to the r2r dac, the sound in usb dac mode is also rendered with distinct musicality. Premium qualcomm bluetooth chip effortless connection and enhanced user experience retro meets modern a dual advancement in both features and experience. Equipped with the qualcomm qcc3095 bluetooth chip and bluetooth 5.4, the dm15 r2r supports standard and high resolution bluetooth transmission protocols, including aptx, aptx adaptive, aptx hd, and sbc. Bluetooth transmission is supported for both cd input and usb input. A brand new visual interface makes pairing and connecting bluetooth devices perfectly clear. Slim at an inch, superior in its league a ldquopowerhouserdquo among portable cd players ldquoportablerdquo cd players are becoming increasingly large, undermining their original purpose of being easy to carry and move around. The dm15 r2r has been further refined and slimmed down in size compared to the dm13. By uniquely integrating high performance and a wealth of features into an extremely compact and portable form factor, it stands out from its competitors. Global basseq 24 sound presets with 3 bass modes and 8 built in eq presets, you can combine these for up to 24 dynamic sound presets. There is even a specially tuned retro sound preset that delivers a rich, analogue, and classic sound flavour. Since selecting bass or eq affects the output level, please adjust your volume as necessary. The all purpose powerhouse fully capable the device combines a portable cd player, hifi grade usb dac, high resolution usb cd bluetooth transmitter, and a usb cd digital transport all into a single unit offering far greater versatility and compatibility than comparable portable cd players. Hd tft display effortlessly control your music the players retro ui theme blends modern and vintage styles for a pleasing look that is also easy to use. It clearly and intuitively presents information such as battery power, operational mode, eq settings, sampling rate, bluetooth connection list, and more, allowing you to easily maintain control over your audio and enhance your musical enjoyment. Vintage mechanical controls the overture to a great listening experience this brand new retro design incorporates mechanical buttons, keys, and knobs that one can tangibly interact with, making control simple and easy to learn. Furthermore, the real tactile feedback from every single action allows you to fully experience the beauty of cd listening through sight, touch, and sound.
