Bakoon Products SCL CAP-1003 Small headphone amplifier

A CAP series has been born that produces high -quality music life in the size of just fit in a narrow space from Bacoon Products.
CAP-1003 is a very small headphone amplifier of 75 (W) x30 (H) x100 (d) mm only 180g. Since the output stage is designed so that high quality tones can be obtained by pure A -class operation, you can enjoy not only music but also the sound of the movie.

Bacoon Products change the logo and name to SCL (SATRI CIRCUIT LABORATORY).

Since CAP-1003 is a non-regression amplifier, it has a vast frequency characteristic and a wonderful transient characteristics. Insert headphone terminal outputs such as smartphones, tablets, mobile music players, etc., reduce the load on the player's headphone output to reduce distortion, and have a new IC "HBFBC" that has newly developed the signal. Drive the headphone in the output circuit.

Like other CAP series, power supply can be supplied from+5V, USB or mobile battery.
Mobile batteries have a large capacity, such as 10000mAh, so you can operate well without narrowing the operating current. The stable operation is realized as ± 5V inside. There are two inputs, RCA and mini vonjack, which can be selected by the front input switching switch.

The noise is 0.0011mV and the S/N ratio is -119.2db.
The noise characteristics of the output circuit combined with HBFBC are excellent, and the playback sound does not occur even when the amount is low.
In addition, the headphones are driven by low impedance, so you can clearly hear the fine sounds clearly due to the synergistic effect with the low noise.
The frequency of -3db is 3.28MHz. At 100kHz, both phase and frequency characteristics are flat. Since the frequency characteristics are wide bandwidth, the regeneration of the square wave is also beautiful.

The first impression is very small. Originally, Bacoon products are compact, except high-end, but this headphone amplifier CAP-1003 is outstanding among the new small CAP series. I am glad that there are two types of RCA and earphones in the body that is small enough to fit in the palm. The sound is good again. I can't pull my hands because it's a bakoon. It seems that the air that had been hazy was clear, and thanks to the improvement of the outlook, the distant scenery was clearly visible. The vocal that moves in the YouTube's live video has a firm voice, and the high -pitched treble passes through the live venue. The heat of tens of thousands of people can be conveyed in a sense of realism. The sound separation is good, musical instruments, vocals, and the crowd of crowds are not melting, and it's not noisy. This will enjoy the movie quite a bit. It is excellent that a portable battery can be used by USB connection. Now you can take it out around the world. It is good to say power noise.
