New Tube Amplifiers

Sat, 29 Nov 2025 22:11:00 +0000

The highly acclaimed G-811 tube amplifier is available again — delivering outstanding sound, exceptional signal purity, and a wide soundstage. This model is based on a circuit designed by Japanese engineer Shishido, which has achieved legendary status for its musicality and natural sound quality. It is ideally suited for all genres of music, from classical to hard rock, metal, and pop. It reproduces vocals with all tonal nuances and intonations, as well as instrumental parts with precision. See more here.

The second renewed model is 6S41S (previously available as the Led Zeppelin model using the same tubes). It is a powerful amplifier with excellent sound performance. Thanks to the characteristics of the 6C41C tubes and the Class A circuit, the 6S41S offers an exceptionally linear signal with low noise levels. Its microdynamics and spatial presentation are clearly expressed in both acoustic and vocal music. See more here.

The Loftin-White circuit (more in the blog) is a special type of Single-Ended (SE) Class A tube amplifier circuit developed by engineers Loftin and White in the early 20th century. It is known for its direct coupling between amplifier stages, eliminating interstage capacitors that are traditionally used for signal transmission between stages.

This circuit is particularly popular among audiophiles who seek maximum sound purity and musical expression. It pairs exceptionally well with high-sensitivity speakers, delivering a warm, detailed, and naturally flowing sound.
