 Audiophile grade components mounted on solid aluminum and steel construction chassis for 

• 

the highest possible signal integrity and reliability, even under difficult circumstances. 

 High current, high voltage discrete output stage in class G and H configuration, capable of driv-

• 

ing even the most demanding speaker systems and combinations. Either at low or high power, 

you 

will

 hear the 

Champ-One

 difference.

 Switchable “tube” characteristic is a unique feature on discrete power amps. It allows you to 

• 

enjoy a warm, softer, more transparent sound resulting in zero listening fatigue.

 Custom designed side mount heatsinks, in combination with class G and H amplifier topology 

• 

have made it possible to create a discrete high power amplifier without the need of a noisy dust 

collecting cooling fan inside the enclosure. This means less maintenance, no annual fan or 

dust filter exchange procedure, no more amplifier cleanout … 

no unwanted noise from cool-

ing fans

Champ-One

 relies on convectional cooling only, a unique feature in this output power 

class !

 Temperature controlled program power control: the APC circuitry continuously monitors output 

• 

power demands and amplifier temperature and will automatically adjust program power to 

avoid overheating and thermal cycling.

 A stunning 46.000 µF of high grade electrolytic capacitors, high power toroidal transformer for 

• 

ultimate power reserve. 

 Self-supporting low resonance steel subframe. Torsion free front and side panel construction 

• 

with integrated heatsink assembly.

 Solid aluminum brushed front panel with removable 19” brackets and handles for use in a rack 

• 

or as a standalone unit in high quality audio systems.

 Multi purpose input and output connector configuration: genuine Neutrik® speakon connectors, 

• 

speaker wire binding posts, XLR input connectors, RCA connectors …
