The understated elegance of its minimalist Swiss exterior conceals a power amplifier of remarkable sophistication and potency.
Any serious audio system will benefit from the rarefied level of technology implemented in the Orpheus power amplifiers.

With high quiescent current the Orpheus Three S amplifier combines the speed and authoritative deep bass of the most powerful transistor designs with the midrange glow, smooth high frequencies and overall musical warmth of the finest tube designs.
Housing this level of power and performance in such an elegant low-profile enclosure optimises the ultra-short signal path. The transformer is ideally positioned to eliminate interference with the careful selected active and passive components.

Power Loop
Unlike the conventional feedback loops found in the vast majority of traditional amplifiers, the proprietary Orpheus Power

Loop monitors both voltage and current, executing corrections as required at extreme high speeds for rock-solid stability to maintain the purity of the audio signal.

Orpheus Power Loop constant power amplification modules ensure coherence and lightning-fast response across the entire frequency spectrum, regardless of loudspeaker load. In the presence of a resistive load, Orpheus Three acts as a voltage amplifier. In the presence of a reactive load, the load is controlled during transients and current is adjusted to meet the requirements of the loudspeaker.

Designed to fit a single rack unit (482 x 370 x 44 mm)..

Features:

• 2 x 40 Watts (Orpheus Three S stereo)
  
• Single-ended phono inputs and balanced XLR inputs
  
• Efficient heat dissipation via internal chassis-coupled heatsinks
  
• Sleek, slim-line brushed aluminium face plate mounted to non-resonant heavy-gauge black powder-coated steel chassis.

This unit is a 2004 model, used only approximately 6 hours.
