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 is especially well suited to this task
due to its extremely high input impedance. The signal then
passes to the clean gain stage.
In order to ensure the shortest possible signal paths, all swit-
ching functions are handled by optimally positioned, encapsu-
lated, gas-filled relays with gold-plated contacts—the switches
themselves only trigger the relays. Since resistors also greatly
affect audio quality, the entire audio signal path utilizes pain-
stakingly selected resistors with 0.1 % tolerance.
The op-amp circuits use premium FKP foil condensers, which
sound much more open than ceramic types and provide more
natural dynamic response.
All circuit boards have oversized grounding surfaces for optimal
shielding.
