Tenor amplifiers are the finest analogue amplifiers money can buy and represent the collective genius of designer Michel Vanden Broeck.

As Tenor Audio’s Chief Engineer & Designer, Michel’s life work of over 40 years has culminated in the most musical amplifiers known to mankind.   Zero perceived distortion is the benefit of the proprietary technology Harmonic Structural Integrity (HSI) which forms the basis of all Tenor products – making for the most musical experience possible outside of the concert hall or recording studio. Unlike all others, every Tenor amplifier is luxuriously crafted with the finest of materials by master craftsman dedicated to ensuring every amplifier is built to exacting old world standards and modern performance.  Tenor – sounding very perfect & looking incredibly gorgeous!

Line 1/Power 1
$126,500 USD

The Line 1/Power 1 dual chassis line stage is the most natural transparent preamplifer in existence!  Quite breathtaking actually!

Built to exacting standards, the Line 1/Power 1 mates perfectly with either the  Tenor 175S or 350M amplifiers to provide a synergistic experience beyond any other known combination of high end audio equipment.

Separating the power generation from the audio signals with separate chassis’ provides an ultra low noise floor and extreme dynamics like nothing heard before.

The Line 1/Power 1 is the standard by which all preamplifiers will be judged!

Phono 1
$61,500 USD

“There are few equals to the Tenor Phono 1 at any price as the Tenor experience is nothing short of breathtaking! It has taken my entire audio system to a whole new level – that I thought would not be possible without changing most of my equipment. For that reason alone, the cost of the Tenor must be considered a true bargain. Perhaps audio’s “Law of Diminishing Return”s has been overcome by Tenor’s Michel Vanden Broeck’s “Laws of Physics”. One thing for certain, this unit is never leaving my house. I wrote the cheque!”
