Cayin N30LE

Cayin placed these tubes in the voltage gain stage once again, where they will exert the most positive influence on N30LE's final sonics. It's the first and the last time Asahi Kasei Microdevices (AKM)’s legacy AK4499EQs will be leashed to Nutubes, marking an historic moment.

High quality, linear open-loop small signal from Korg's low-capacitance, high-bandwidth Nutubes running on high operating voltages then feeds a potent discrete solid-state power stage that drives your headphones.

Hyper Mode ups the entire operating voltage in the circuit, with a 470mF Electric Double Layer Ultracapacitor (EDLC) capable of discharging DC instantaneously to help reproduce the huge, sudden transients of musical notes into difficult loads. 

N30LE's high voltage rails see operating voltages for its power section rise above 7 volts, the linearity of discrete transistors assured as a result. Cayin's discrete headphone amplifier can be operated in Class AB or an optimal Class A, for sonic tweaking with your favourite earphones and headphones.

Differentiating itself from even other flagships that cling to op-amp layouts seeking THX-certification but with inordinate amounts of gain and feedforward/feedback, Cayin's linearity remains excellent already in the open-loop, owing to its high operating voltages and bias.

Those ensure individual transistors are working in optimum condition. Distortion and noise are kept low, without resorting to the excessive use of negative feedback.

Cayin designed a true-balanced differential amplifier to further improve N30LE's linearity, and you can count on common-mode rejection at its best whenever you plug in via 4.4mm preserving its resolution.

It's an output stage that's direct-coupled to improve low-frequency performance, and N30LE audibly plumbs the lowest bass depths. With the extension down low, phase reproduction in the audible human hearing range for taut, hard-hitting and life-like dynamics is excellent.
