Bakoon Products SCL CAP-1003 Small Headphone Amplifier

Bakoon ProductsThe CAP series, which produces high-quality music life with just-fit size, was born in a narrow space.
The CAP-1003 is a very small headphone amplifier with only 75 (W) x30 (H) x100 (D) mm. The output stage is designed to produce high quality tones with a net A-class operation, so you can fully enjoy not only music but also the audio of the movie.

Bakoon ProductsThe logo and name will be changed to SCL (SATRI Circuit Laboratory).

Since CAP-1003 is a no-feedback amplifier, it has vast frequency characteristics and great transient characteristics. By inputting headphone terminal outputs such as smartphones, tablets, and mobile music players, reducing distortion by reducing the load of the player's headphone output, the headphone is driven by a powerful output circuit equipped with the newly developed IC "HBFBC."

Like other CAP series, power supplies are available from + 5V, USB and mobile batteries.
Mobile batteries have a large capacity such as 10000mAH, so you can operate well even if you do not narrow down the operating current too much. It realizes stable operation as ± 5V internally. There are two inputs: RCA and Mini Fon Jack, and you can choose from the front input switch.

Noise is 0.0011mV and S/N ratio is -119.2db.
The noise characteristics of the output circuit combined with HBFBC are excellent and do not cause turbidity to the playback sound even when it is small volume.
In addition, the headphones are powered by low impedance, so you can hear fine sounds clearly by synergy with low noise.
- The frequency of -3db is 3.28MHz. Phase and frequency characteristics are flat in 100kHz. Because the frequency characteristics are wide band, rectangular wave regeneration is also clean.

The first impression is very small. Originally, Bacoon products are compact in size except for the high-end, but this headphone amplifier CAP-1003 is exceptionally small among the new small CAP series. It is nice to have two lines of RCA and earphone input in the body so small that it fits nicely in the palm. The sound is good again. It's a bacoon, so I can't pull it out. It seems as if the air that was hazy to the previous point was clear, and thanks to the better outlook, it seems that even the distant scenery can be seen clearly. In YouTube's live video, the vocals are full of voice, and the high-pitched sound passes through the live venue. The enthusiasm of the stadium with tens of thousands of people is conveyed to the audience. The separation of sound is good, the instrument and vocals, the enthusiasm of the audience do not blend together, it is not noisy. This will make the movie quite fun. It is excellent that a portable battery can be used with a USB connection. This will bring you the world first. Power supply noise is also good.
