Reference Line Preamp "Continuance No.84 MK4"
in our special tube-hybrid technology *
* 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
