Cayin Mini-CD MK2 CD Player

Sold out

The Cayin Mini-CD MK2 brings the CD back to the forefront of music playback. Sleek styling and impressive specifications make the Mini-CD the perfect addition to any hi-fi system. Upsampling support can greatly improve the fidelity of your favorite music, and combined with the audiophile-grade DAC you'll be finding plenty of new reasons to get your CD collection back out. The DAC chipset in the Mini-CD MK2 produces some of the best fidelity and sound quality for any CD player on the market. It's capable of upsampling from 44.1kHz up to 352.8kHz. And if you want to up your game, you can bypass the internal DAC and pair the Mini-CD MK2 with the iDAC-6. The Mini-CD MK2 has a set of digital outputs including S/PDIF RCA coaxial and i²S HDMI interface. i²S is going to take the raw data directly off your CD and send it to the DAC (whereas if you do any other digital output from a CD, it's got to be converted to that output). The VFD dynamic display is classic with a modern look, and the included remote control makes for versatile operation and complete control over your music.

The N7 is the latest in high-resolution portable sound from one of the leading audio manufacturers of premium digital music players.

The discrete 1-bit DAC can native decode up to DSD512 and accept PCM up to 32 Bit/768kHz. Cayin also developed a discrete LPF (low pass filters) circuit to tune the output stage of their 1-bit DAC to closely resemble a smooth and natural sound signature.
