G-811

G-811 Tube Amplifier – Premium SE Class A Stereo Amplifier

The G-811 is a high-end Single Ended (SE) Class A stereo tube amplifier, designed and handcrafted in Latvia, combining precise engineering with artisanal craftsmanship. It is based on the legendary circuit created by the Japanese engineer Shishido, renowned for its natural and musical sound character. This amplifier is made for audiophiles who seek not just sound — but emotion.

Design

Chassis:

• Made from solid oak, zebrawood and plywood, ensuring mechanical stability, natural resonance control, and a visually unique character.
• Metal components provide additional structural rigidity and serve as elegant design accents, forming a finely balanced industrial–organic aesthetic.
• The entire construction is designed as an open platform, allowing the tubes to remain visually exposed — making the G-811 both a functional audio device and a visual centerpiece.
  

Tubes:

• Power Stage: Two Г-811 tubes (read more in our blog), highly efficient tubes known for strong dynamics and impressive macro & micro detail retrieval.
• Preamp Stage: Two 6C5C – a linear and musical choice for the initial signal stage, with exceptionally low noise.
• Driver: Two 6П6С – a reliable and coherent signal driver, perfectly matched to the characteristics of the Г-811.
  

Specifications

• Output Power: 2 x 15 W – suitable for medium to large spaces with high or medium-sensitivity speakers.
• Dimensions: Width 60 cm, Height 25 cm, Depth 37 cm.
• Weight: 29 kg – an optimal weight for stability and vibration reduction.

Sound Characteristics

The G-811 delivers an authentic Class A tube sound with rich dynamics, precise detail, and a warm tonality. The Shishido circuit enhances harmonic content, providing deep bass, clear midrange, and pristine high frequencies. Known for its minimalist approach and clean signal path, this circuit acts as no barrier between music and listener — only purity and transparency.

The sound character can be described as warm but not dark, analytical but never cold. It reveals both the depth of space and the texture of instruments. High- and low-frequency detail remains intact even at low listening levels. Vocals and acoustic instruments sound especially natural and spatial, with a stable stereo base and wide horizontal perspective. Thanks to the Class A design, the amplifier maintains absolute linearity without compression or distortion — even at low volume.

It is perfectly suited for all genres — from classical and jazz to heavy rock, metal, and pop music. It reproduces vocals with full timbral nuance and captures the energy of instrumental performance with ease.

Aesthetics & Functionality

G-811 is hand-built, with great attention to every detail. The point-to-point (spatial) wiring technique ensures minimal interference and high-precision electrical connections. This amplifier combines high-quality audio technology with elegant design, fitting seamlessly into any interior.

The open tube architecture allows the user to see the sound — visually observing the tubes in action. The design blends retro audio tradition with modern minimalism, creating a professional yet inviting appearance.

Overall Impression

The G-811 is an ideal choice for audio enthusiasts who value high-end sound, authentic materials, and unique design. It is not just an amplifier — it is an audio instrument, crafted with a clear focus on sonic purity and emotional impact. It unites engineering precision with artisanal elegance, becoming the central element of any audio system or room.

Created for those who seek more than sound — who want to feel the presence of music.
