The first stage is a custom-made low-noise dual FET while the second stage is clear and high slew-rate vacuum tube 6SN7. The tube output offers warm and spacious music reproduction.
6SN7 realizes a highly transparent sound
Non-inductive winding resistors with the least inductance
High-definition film capacitors are used
Hand selected matching FET
Volume control is EMI shielded
Bypass volume control switching
Switchable RCA and XLR inputs. RCA parallel out.
The newly developed large-sized aluminum insulator combined with new vibration-proof material and high frictional coefficient (grip power) have been employed.
