45 PSE Monoblock Power Amplifier
The M45 is hand-assembled and features point-to-point wiring with silver in both the signal and PSU sections. It does not use global negative feedback, which helps maintain a sense of presence and avoids potential transient distortions or a perceived reduction in liveliness. Many components that define the sound are in-house made, handcrafted by ourself.
