This tube triode mosfet
integrated amplifier use the same philosophie of our combo
PRE/POWER VP04/VM150 :
preamplification for phono and line by triode
output stage by hexfets ( special mosfet )
only local feedback for output stage, no-feedback design for tube preamplifier section
The phono stage is based on this solution:
air of tubes ECC 81/12AT7 for phono amplifierdouble triode ECC 82/12AU7 for line/cd inputs
passive riaa stage with accurate components @ .5 % tollerance
A lot of new
and original electronic architecture have the circuity of VFI70:
optical bias control on triode
absolutle zero feedback on tube section
very low feedback on Mosfets section
only three polipropilene capacitors on signal path
As all our realization the components are only
premium grade.
Sophisticated power supply circuity with four independent
section:
power mosfets, filaments, anode plate, phono stage.
The class of sound of the VFI 70 can compare also with most
important solid state Pre/Power combo probaly the VFI 70 sound
better: more transparent, detailed and better soundstage.
CONVENIENCE AND PERFORMANCE
Internal output stage attenuators for better fine tuning sensibility.
Hi - quality potentiometer as audio premium grade
Version VFI-70mc comes in two boxes (separate power supply model PSU-70)
Cherry wood veenering for lateral sides (optional)
Motorized potentiometer with remote control handset (optional)
