More info:
Premium model uses sealed selector switch and sealed balance/volume controls, and Jenalabs cryod wire in the signal path.
DC regulated filament power supply
Tube dampers
Extremely low distortion, typically .015% or -74db down total harmonic distortion, without any global feedback.
Black body with silver knobs as well as the three position "frequency profile" switch on the back and a switch for changing the power polarity. It uses a single E88CC/6DJ8/6922 tube... modern production tube and one Amperex Bugle Boy.
Its a great sounding preamp...but I have an Aloia preamp to match its amp coming soon, so bye bye.
Specs:
A robust 4 stage power supply provides better isolation from hash and interference from/through the rectifiers, transformer and AC line, for a cleaner, more open sound.
Power Line (AC) power reversal. One can choose the better sounding position.
