Precise: Sony SS-AR2 Loudspeaker

Audiophiles know that a speaker is more than a medium. In fact, Sony’s flagship SS-AR2 is an instrument.

Just like a piano, it’s crafted chiefly out of wood—and not any ordinary kind. As with the earlier SS-AR1, Sony sources the wood for the SS-AR2’s baffle board from the Japanese island of Hokkaido, where winters are extremely cold, resulting in hard maple with a tight grain. The speaker’s side and rear panels, however, are made from Finnish birch. Both materials hold together without glue; the units are the product of a cabinet-making company that provides precision components for musical instruments.

The SS-AR2 Loudspeaker is a four-unit, three-way, floor-standing, vented-box speaker system.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
