A modern portable amplifier with a classic circuit design. The National+ is an Opamp-less design; using 10 matched pairs of triodes in a discrete component layout. This approach to amplification delivers a robust sonic presentation that compliments a wide variety of musical styles and tastes.
The National+ housing is CNC’d from a single block of aluminum, providing exceptional protection for ‘on the go’ applications. Sized at just 3.38”x1.8”x.75”, its diminutive footprint conceals a versatile performer. Capable of pairing with sensitive earphones when in ‘low gain’ it is also capable of driving planar magnetic headphones while in its ‘high gain’ setting.
The easy to use National+ features a 3.5mm single-ended input and output. This offers a simple solution to amplify your portable high resolution digital audio player or the sensitive low level signal from your favorite DAC. Its output provides 3 gain stages to provide the perfect match for an audiophile’s earphones and/or headphones.
Carrying case, USB cable for charging and ALO audio amp straps included with The National+.
