The best of both analog and digital! Hybrid tube amplifier
The front stage (pre-stage) is a vacuum tube with a soft, warm, unique tone, and the rear stage (power stage) is a digital amplifier with low distortion, clear sound quality and driving force. By combining the unique tone of the vacuum tube, which expands the appeal of music, with a small but powerful digital amplifier, achieved a warm, yet clear sound quality. We have generously poured in our technology, which has been developing vacuum tube and digital amplifiers for over 20 years. Enjoy authentic sound that you would never expect from a small amplifier.
Compact size and design that can be installed anywhere
It's very compact, with almost the same size as a CD jacket (130mm wide x 145mm deep x 77mm high, including protrusions)! It can be easily placed around your desk, under your living room TV, or on your bedside table. It has a design that can be enjoyed as interior decor. It can also be used with a portable power source (compatible with DC 12V output), so you can take it out for camping or sleeping in your car.
*When using with a portable power source, a separate dedicated cable may be required. Please check the specifications of the portable power source for details.
Turn your desk into your own high-quality sound space
Connect it to your PC, smartphone, or tablet with a single USB cable to enjoy digital audio sources such as music streaming services and YouTube. You can also connect it to a record player (please prepare one with a built-in phono equalizer) to enjoy analog audio sources.
The SWL-T01 is the perfect device for listening to music on your desktop.

Changing the Way You Experience Music
Richer sound with clearer layers.
While playing music on your smartphone or computer is already convenient, adding a headphone amplifier greatly enhances the audio quality, revealing richer and more detailed sound layers. This transforms your daily music time from mere background noise into a personal auditory feast. Whether after work, during chores, or in those moments of relaxation before sleep, why not immerse yourself fully in your favorite melodies in your favorite spot at home?
Scene: Bedside music experience at night before sleep
To commemorate the company’s 100th anniversary, both the amplifier and speaker set were designed and made in Japan.
The SWL-T01 amplifier features a retro-style metal mesh cage enclosing its vacuum tube (12AU7), while the SW-SP2 speakers combine walnut woodgrain panels with linen fabric grills, creating a warm and natural aesthetic.

Compact and easy to place, this amplifier and speaker system measures just 40 cm in width — small enough to fit neatly on a side table.
Whether unwinding after work, taking a break from chores, or relaxing before bedtime, it lets you enjoy high-quality streamed music and video with rich, room-filling sound.
The SWL-T01 is a hybrid vacuum tube amplifier: the preamp stage uses vacuum tubes, while the power stage employs a Class D amplifier.
When paired with the SW-SP2 speakers, which are equipped with passive radiators on both sides, the system delivers sound that is warm, smooth, and full-bodied.
The SWL-T01 offers a USB Type-B input (via a Type-C to B cable) for direct digital connection, along with an optical (OPT) input for devices such as CD players.
It also supports AUX input, allowing flexible playback using Bluetooth transmitters or receivers.
In addition to connecting to SW-SP2 speakers via the SPEAKER terminals, the Φ6.3mm headphone jack provides a private listening option — perfect for enjoying music in full detail, even late at night.
