* in our special tube-hybrid technology we combine the precision,
power and speed of transistors with the smoothness, clarity and
richness in tonal colour of tubes

* Unrivalled musicality, precise, transparent, spatial and very dynamic reproduction of music, 
  powerful, deep bass, exact timing with live-character

* The voltage amplification with channel separated double triodes ECC83 and a 
  professional class A output stage determine a widely extended frequency

  response, an excellent channel separation and an extremely sweet tempered 
  triode distortion performance

* Contact optimized ceramic tube sockets

* Completely new developed circuitry without a negative overall feedback 
  with only a few components in signal path, stabilized anode voltage and filament voltage, 
  as well as the softstart management

* Only a few components in signal path

* Complex low-noise voltage stabilisation for solid-state section

* Stabilized anode voltage and filament voltage, as well as the softstart management

* Relais with gold plated silver contacts

* ALPS high grade potentiometer

* Preamp and 2 external 50VA power supplies (tube- and solid state sections separated)
   integrated in heavy, massive, solid high-end-casings with high glossy black acryl fronts

  and resonancre absorbing polished chrome feet

* All input jacks and output jacks are gold plated

* Remote control for volume including a freely programmable,

  learnable infrared transmitter as an option avaliable (LAZYBONES)

* Every device comes along with "its own" original measuring record of the frequency response, 
  further measuring records are available on request
