D8 Reference Class HighEnd Tube Preamplifier, under any aspect is unbeatable in its price class and far above, as fantastic as the DOGE 6 CD player described above, absolute top in playback, design as well as quality.
It fully is designed in dual mono layout with 2 separate power transformers, two totally symmetric circuits and extra power source for control unit.
D8 adopts classic SRPP amplifying circuit with high resolution and wide dynamic, reflected in frequency response of 5 Hz to 200 kHz ±1dB as well as SNR >100dB, with 1x 12AX7 in input stage and 1x 12AT7 in duo-phase stage for each track.
Top-quality components, such as polypropylene capacitors, gas contact relays controlled by microprocessor, ALPS motor-driven potentiometer with channel balance < 0.3 dB, metal film resistors, high-level RCA jacks, gold-plated, etc. are used.
2 Output groups RCA, no.1 with 20 dB voltage gain, no. 2 with 10 dB voltage gain, for better adoption of different power amplifiers are available and 1 output group balanced XLR additionally
IR remote control is adopted as well as the control output for connection of power amplifiers to remote linkage operation, including special 3 core cable (1x
output, 2x input) included in supply.
Additionally the amp has a build-in PHONO stage, switchable between MM Tube and MC JFET's amplification circuit, perhaps one of the finest available presently adopts both, MM as well as MC cartridges. Design of its circuitry tracks RIAA compensation curve with absolute accuracy and precision.
Enclosure is in dark-blue, with stainless steel front panel, polished.
