      This class-D board uses class-T architecture, with integrated STA508 chip supporting dual channel audio amplification, to create exceptional sounding custom multi-channel systems. Compatible with power supplies ranging from 10V to 30V DC, it can be used in many audio applications. The amplifier has four channels with the same power of up to 100 watts each, resulting in outstanding sound quality and versatility. You can employ any number of channels you like, and leave the others unused.

       

      This amplifier is exceptionally well designed, with a lot of power reserve, high fidelity, low distortion, good S/N ratio, high sensitivity, and full protection with heatsink and fan. These ideal characteristics make this amplifier a candidate to become the basic building block of your future high fidelity system, or it can become the element that will upgrade an existing system.

      Een heel mooi versterker ontwerp.

      Sauber verarbeitet, macht optisch einen sehr ordentlichen Eindruck, einzig das Lüfterkabel sitzt etwas stramm. Der Klang ist prima, das Teil hat auch ordentlich Dampf, nachgemessen habe ich aber nicht. Alles in allem bin ich sehr zufrieden.
