The desing of this tube preamplifier uses only two tube for
one pair off ECC 81 low noise for phono section and one pair off ECC 82 for line stage and output cathode follower for to have low impedance output.
The architecture design don't incorporate negative feedback,the phono section adopt passive RIAA equalization with precision components at 1% and special optoelectronic cathode coupled semiconductor bias control.
High level stage is optimized for C.D. and DAT source,better control is possible with interface board card model IBXVP04 (optional).
The power supply is regulated by I.C. using Mosfet transistor and employ only high quality electrolitic capacitors,metal foil resistor; the ground circuity use star point configuration with hard wire made.
Active and passive electronic components are only premium grade:
The results is a great soundstage:
hi-dinamic,detailed,transparent sound.....a perfect sound
