AnandTech heeft een review online gezet van de Altec Lansing Ada 890. Dit speakersetje kan zowel in 2.1 als in 4.1 opstelling gebruikt worden. In Quad modus heeft het helaas last van een vervelende bug die ervoor zorgt dat vrijwel geen bas te horen valt. Dit maakt de speakers wat minder geschikt voor de gamers onder ons:
One major drawback to the system is the malfunctioning Quad mode. For gamers, this would be the primary listening mode; it allows for four channel soundcards to create an audio environment to accompany a gaming experience. However, the phase cancellation in the system renders this input unusable.Besides the problems with quad mode, the system is fairly responsive sonically. Its treble and bass adjustment points are well suited to fit the system, and allow for the sound to be tweaked as needed. Overall, the analog inputs are warmer than the digital ones, though they add presence to the low midrange in the sound. The digital input is very clean and consistent, though the headroom seems a little low.
The system sets up incredibly easily. Everything is color coded, and the full page, full color diagrams present multiple configuration options. For listeners that don't have a front mounted headphone jack, there is one provided on the front left pedestal.

Voor andere toepassingen is het systeem echter wel goed te gebruiken volgens AnandTech. Lees de complete review hier.
