Since SHIROSHITA was founded in 1923 as the Shiroshita Silk Reeling Factory, we have about 90 years of experience as a company having “MONOZUKURI – the traditional Japanese concept of craftsmanship”. The Shiroshita has specialized in developing Professional Monitoring Headphones and Audio Equipments for professional recording studios and broadcast since the 1970s. Over the past years, we have been developing headphone and audio equipments and working closely with many international companies on OEM basis.

We make All high-value Audio equipments that are designed and built in Japan, with the attention to detail and quality throughout.

■Using a Digital-Analog Hybrid Technique
The SWD-TA10US tube/Class D Hybrid Power Amplifier combines the best of both the solid state and tube technologies.
The Power Amplifier utilizes single 12AU7 tube in the preamp section, and is equipped with a high-efficiency Class-D amplifier.
The hand-selected 12AU7 vacuum tube glows softy in orange and combining the advantages of tube and digital technologies provides a warm, natural and smooth sound.

■Input and Output terminals
The SWD-TA10 is a compact integrated stereo power amplifier and high-quality headphone amp.
The back panel of the SWD-TA10US has a pair of RCA input jacks, two pairs of speaker output terminals and a 3.5mm mini-jack.
The RCA input jacks can be used to connect an external CD player/DAC with analog outputs.
The speaker output terminals accept passive speaker cables terminated with naked wire or 4mm Banana plugs.
The 3.5mm mini-jack (ACTIVE SPEAKERS) offers connection for an active speaker with a built-in amplifier. Or you can also add an additional subwoofer. This amplifier runs the audio signal through a tube circuit and feed them to your active speaker. It will certainly affect the sound.

■Audiophile Headphone Amplifier
The front panel has a volume control and a 3.5mm headphone jack.
Over the past years, we have been developing headphone and audio equipments and working closely with many international companies on OEM basis.
We pay attention to the impedance matching of devices for high performance headphones.
This Power Amplifier has output transformer to adapt the amplifier output to typical headphones impedances.
The optimized output transformer assures that maximum power is transferred from the amplifier to the headphones.

We also offer the SWD-DA10US High Resolution USB D/A Converter. The DAC has a 3.5mm headphone jack.
You may detect a sound-quality difference between the SWD-DA10US D/C converter and the SWD-TA10US Hybrid Tube Power Amplifier. The SWD-DA10US gives a cleaner sound and more accurate representation of the curve. The SWD-TA10US delivers more warmth and tube flavor to the sound.

■Compact and Stylish Design
The SWD-TA10US measures W145.4mm×H40mm×D165mm (Protruding part not included) and is housed in a custom textured aluminum-and-steel case with a clear front panel. You can choose to mount this Amplifier either horizontally or vertically, depending upon your equipment configuration.
The attached self-adhesive clear rubber feet bumpers are placed on the bottom of the Amplifier to give it more stability and to help protect it from scratches.

We offer the “SOUND WARRIOR Series”, consists of the SWD-DA10US High Resolution USB D/A Converter, the SWD-CT10US CD Transport and this SWD-TA10US Class-D Stereo Power Amplifier with 12AU7 Tube Preamp. These compact devices can be stacked on top of each other to save space. You will be able to create your own desktop audio system and enjoy the playback of high-resolution audio files.
