Class A Instrument Input
The Instrument Input is a fully discrete impedance converter
that also operates in class A mode. It is based on a low-noise
field effect transistor that, due to its extremely high input impe-
dance, is especially well suited to this task.
Relay switching
In order to ensure the shortest possible signal paths, nearly all
switching functions are handled by optimally positioned, encap-
sulated relays with gold-plated contacts (the switches them-
selves only trigger the relays). Since resistors also greatly affect
audio quality, the entire audio signal path utilizes painstakingly
selected resistors with 0.1 % tolerance.
Foil condensers
The op-amp circuits use premium FKP foil condensers, which
sound much more open than ceramic types and provide more
natural dynamic response.
