The new L30 can be used as both a headphone/IEM amplifier or a preamplifier
The L30 headphone amplifier incorporates NFCA (Nested Feedback Composite Amplifier) modules from the flagship A90. The latter apparently provide lots of power at low distortion.
It also reportedly incorporates Topping’s UHGF (ultra high gain feedback) technology in a voltage-current hybrid feedback architecture.
The L30 also has three toggled gain settings at -9.9db (for IEMs), 0db and 9.5db.
It can also be used in two modes: amplifier and preamplifier modes. The preamp is accessible via a dedicated switch on the front panel.
The rear includes a socket for the power supply plus the usual headphone inputs and outputs.
An external AC adapter is included plus a single-ended 6.35mm socket on the front that sits alongside the gain control. Spanning 320 x 100 x 134mm, the price is $110.
