FiiO CP13 Portable Stereo Cassette Player

Classic way to listen | Modern presentation

During the 1980's and 1990's, cassette tapes were popular, and cassette players accordingly were popular among multiple generations.

Today, however, the supply chain for cassette players is nearly non-existent, making the initial stages of the CP13 project extremely difficulty - nearly leading us to cancel the project.

But after investing much time, effort, and deep cooperation with the supply chain, we were able to slowly continue working on the CP13 leading to its current release. We may be nostalgic for the classics, but we are always looking for new ways to present the music. We want to be able to relive those days of familiar and comfortable pure analog sound

High voltage motor power supply

The CP13's motor is powered by a high voltage 4.2V power supply, more than the 1.8V or 3V typically found in today's cassette players. This power supply works in tandem with a motor speed stabilization circuit, which increases the drag on the motor as necessary to ensure stable movement speeds - which mitigates unwanted pitch changes and also allows the CP13 to be able to handle more cassette tape types.

Superior choice Custom balanced amplification head

Regardless of how much it would cost, we negotiated with our supplier to only select heads of high enough quality, which ends up being less than 40% of what is produced. Furthermore, we strictly control how the CP13 is made to ensure minimal differences in output between the left and right channels, far less than what is found in typical current cassette players. The magnetic head also uses a thickened head cover, which better shields the head from external interference. This also greatly reduces the wear of the magnetic head during playback, allowing it to last longer.

Unlike the single-ended signal acquisition typically found in current cassette players, the CP13 employs a differential circuit for balanced acquisition of signals from the head, ensuring more stable signal transmission, higher signal-to-noise ratio, and lower distortion.

Fully analog circuit 100% pure analog sound

For truly analog playback, the entirety of the CP13's audio circuit uses analog devices - from the magnetic tape head all the way to the signal amplification.

The result is a classic, unmistakably analog sound.

A classic's came | Audiophile op-amp JRC5532

The CP13 employs the renowned JRC5532, known to some as the classic "King of op-amps." This op-amp is deployed in a fully analog audio circuit that provides a familiar, pleasant sound that will surely leave an impression.

Long battery life 13 hours of capable lithium battery

The CP13 employs an 1800mAh lithium cobalt oxide battery, chosen for its ability to provide robust power for longer periods of time than ordinary batteries. In fact, the CP13's battery allows it to achieve 13 hours of battery life and 268 days of standby time.

Dual-mode power supply | Continuous great sound

The CP13 is powered by a lithium battery, which can be recharged through the USB Type-C port when connected to a 5V power adapter. And FIIO's vast experience in designing safe charging circuits with protection mechanisms ensures you can use the CP13 while charging worry-free.

Making it count Every last inch

Though ultimately restricted by the size of the cassette player's movement, FIIO engineers paid much attention to making the CP13 as compact as possible. Through the integration of manufacturing and structural design ingenuity, the CP13 ended up only being 31.8mm thick, making it thinner and more compact than most currently produced cassette players.
