One glance at R4i and youll desire one. Listen and this emotion grows stronger because R4i produces a stunning sound that you will simply not expect from such an attractive and compact design. Comprising a multi format CD player, iPod dock, USB playback port, DABDAB+FM tuner and auxiliary inputs allied to a powerful amplifierspeaker system the R4i is in many ways a traditional music centre, though one designed and engineered for the 21st Century. The R4i is the result of our desire to design and build the best small audio products available. As an example, most compact systems use amplifier chipsets for simplicity and cost, but for R4i we developed our own Class A-B amplifiers using discrete component technology. This complex technique is usually only found in high quality, high value audio separates.
