* 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

* Channel separated double triodes ECC83, a passive RIAA equalisation and a professional, 
  class A output stage determine excellent channel separation and an extremely sweet tempered 
  triode distortion performance

* Contact optimized ceramic tube sockets

* Completely new developed circuitry without negative overall feedback and 
  with only a few components in signal path

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

* Stabilized anode voltage, filament voltage and voltage for softstart management, 
  additional mute function

* Adjustment of capacity to MM cartridges and adjustment of resistance 
  to MC cartridges with high-quality code switches

* Extremely high RIAA precision of +/- 0,10 dB

* RIAA 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 resonance absorbing polished chrome feet 

* All input jacks and output jacks are gold plated

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