Thrax ORPHEUS cost no object "as new" Phono Preamplifier in Black with LCR RIAA Equalizer “Highly Recommended” :


Known as One of the worlds finest Phono sections.

Just lowered to make this an even more outstanding deal ‼️

Looking for the RIGHT BUYER and lowered for a fast and friendly sale.

Multi input micro processor controlled phono stage based on tube gain stages and LCR correction. 



Features :

  • Built-in step up transformer


  • Programmable gain and loading


  • Accepts both balanced and unbalanced input signals on RCA and XLR connectors

  • Switches ground plane with input selection preventing ground loops


  • Balanced and unbalanced output


  • Programmable ground arrangement for large systems


  • Programmable absolute phase per input


  • Choke input rectifier for lowest switching noise


  • Shunt regulated constant current PSU for lowest noise and best dynamic behaviour

  • Modular construction


  • Microprocessor controlled


  • Interlocking solid aluminium chassis







  • Orpheus
    uses two tube gain stages with zero feedback and a passive LCR
    equalizer with 2
    inputs on RCA and one on XLR connectors. All inputs are balanced
    differential unless the grounding option is engaged on the RCA inputs.
    As we switch the ground plane
    when switching inputs there are no hum loops or induced ground
    noise. 

    The input stage is a super low noise D3a German Post tube used as a
    triode. Loaded by a constant current cascode it provides the necessary
    gain and output impedance to feed the custom passive LCR RIAA correction
    following it.

    The switchable input transformer interfaces to MC cartridges and has selectable gain and loading impedance.  

    The equalization is passive and the next stage is another super
    low noise tube loaded by a transformer to bring the signal up to the
    necessary level and provide complete isolation of this sensitive circuit
    from the following components.    
    The filter is out of any gain loops and sits between the two gain stages protected from any unpredictable influences.    
    The equalization is realized through the use of constant impedance
    LCR filters using coils wound with OFC wire and silver capacitors.    
    This way the input stage sees a constant load, making its behavior predictable at any signal level.

    The
    power supply of Orpheus uses a choke input full wave tube rectifier
    arrangement. This eliminates switching noise and any other disturbance
    that comes before the choke. The other benefit of this topology is that
    the choke keeps the voltage on the capacitor bank constant.    
    All this is governed by a microprocessor switching the appropriate
    combination of relays and monitoring the status and incoming command.    
    The chassis is milled in house from solid plates of different
    thickness aluminium that are interlocked together to form a ring like
    structure.


    We have the power supply mounted on the left sidewall of this structure
    and the signal transformers on the right side. Two semi-flexible bars
    on which the motherboard and its heat sink are attached, which then
    support this ring.   
    The top and bottom plates link all sides of the ring with the
    flexible bars and the feet made from carbon doped plastic on flexible
    screws.    
    There are no screws visible anywhere on the chassis. And the chassis feels like a solid block.
