COMPANY SOUND:
The Lamm amplifiers have a very natural, real, true-to-life sound. Their naturalness cannot be emphasized enough - music just sounds 'right' through these amplifiers. The right tonality, the right delicacy, the right soundstage.

These amplifiers like the application of plenty of vibration control tweaks. We have had great success with the use of the Acoustic Dreams amps stands, and, especially, the rather more expensive HRS isolation platforms. These help reduce distortions caused by vibrations and reveal that these amps are quite capable of deep, controlled bass and will not collapse into a wall of sound under the onslaught of large numbers of instruments playing all at once.

These amps use the same 6C33C-B tube that top-flight amps like most OTL (output transformer-less) amps use. These amps have a very high-quality output transformer that not only helps them drive many varieties of speakers - but which as so good they can fool many listeners into thinking that they have no transformer at all (especially when good vibration control is in place).

COMPANY SOUND:
The Audio Note 300B amplifiers have a very dramatic, articulate sound with an amazing amount of bass control. For most reasonably easy to drive speakers, they produce enough power to provide real, powerful, instantaneous macro-dynamics that few if any other amplifiers are capable of. It is this capability, to provide the strength and power of natural dynamic swings (which is missing in most audio-reproduction systems) that really helps to make Audio Note amplified music so engrossing, so filled with emotion. There is the slightest amount of bloom, which also may be more true than not, and their tonality is spot-on.

The separation between the various instruments in the soundstage is first class with the Kegon amps and helps keep the music from collapsing into a morass of noise during large crescendos and/or with music with large numbers of instruments.

This is the way music sounded when I was young and less cynical. These days most music sounds cold, as the ears are seemingly unwilling or unable to fill in the emotions and nuances that are usually stripped from the music by the reproduction component chain. These amps reveal the emotion, the romance, the drama that the musicians put into the music. This is the way music is supposed to sound - like music.

This scoring below is based on the Audio Note Kegon

COMPANY SOUND:
These OTL (output transformer-less) amplifiers excel in the reproduction of the details, micro-dynamics and tonality of the music, lending to a very exciting listening experience.

The 75wp and 15wp amps, by eliminating the output transformer, eliminate one a part that otherwise lies in the path the music signal takes through the amplifier robbing the signal of a little of its purity. But, because the output transformer is traditionally used to help match the amplifiers output impedance and voltage to typical speaker loads, amps without this transformer are usually only able to drive very easy-to-drive speakers - the Tenors being no exception. The 75wp and 15wp are not designed for speakers with large impedance swings or impedances that go below 4 ohms.

These amps use the same 6C33C-B tube that top-flight amps like the Lamm amps and almost all other OTL amps use.

The 300Hp is not yet released.
