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+.

The LS-H70A was designed to be the ideal bass-reflex two-way speaker for the Reference01 Series. The speakers are compactbut pack a big punch. At 70W maximum input they can be combined with a variety of amplifiers and receivers. The woofer diaphragm measures 12cm and the soft-dome tweeter, 2.5cm. The speaker cabinet is mounted in a wooden full-scale frame of 5.7 liters. On the very first listen users will notice a rich bass emerge from this compact system. Using premium components, the inputs are screw-type gold-plated terminals, allowing you to design your ideal desktop system.
