We are very proud to announce that The Lotus Group now represents SW1X of England. The designer, Slawa Roschkow is a huge proponent of Non oversampling, zero flittering R2R tube DACs. We have made the first sale ever of their Level V DAC. This will be custom DAC V Special with the following specifications:

  • · Non-oversampling – zero digital filtering DAC design
  • · Specially selected and harmonically matched component & material quality
  • · Discrete transistor shunt voltage regulated power supplies
  • · Dynamic Element Matching (DEM) powered by an asynchronous valve clock (vintage E180F and EAA91 tubes)
  • · Directly Heated Triodes valve output stage, DC-core signal output transformer coupled, zero negative feedback
  • · Passive I/V conversion via specially selected resistors
  • · Directly Heated double diode tube rectified CLCx2LC (3 x choke filtered) power supply
  • · Supports up to 24Bit/96kHz (optional up to 48 kHz only) digital coaxial S/PDIF signal input
  • · Pure copper chassis with panzer holz feet and 16mm panzer holz base
  • · XLR AES/EBU input and balanced XLR output
  • · Fine silver wiring in selected places
  • · Black Gate capacitors around TDA1541
  • · Black Gate capacitors in the HV power supplies in crucial places
  • · Super HiB DC-core mains transformers 3 x for digital and DHT/DHD power supplies
  • · Super HiB DC-core chokes for HV power supply
  • · Copper wound DC-core Super HiB signal output transformers
  • · Inter-stage signal decoupling capacitors: out of production Jensen Copper Foil in Oil in copper can
  • · Vintage NOS Globe 45 tubes
  • · 80 or 5Z3 tube rectifier
Needless to say we are quite excited. As with all finely handcrafted items there is a substantial lead time so I won’t be able to report on it for some months.
