The desing of this tube preamplifier uses only two tube for
channel-stage:
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
illusion!!!
CONVENIENCE AND PERFORMANCE
Optional plug-in card to fit inside the
VP-04:
