The Pre2 DAC separates the pre amp into its own chassis and provides a dedicated power supply which means the pre amp can resolve more detail. Complete with a built-in DAC the pre amp is compatible with a very wide range of sources such as CD players streamers or your TV digital audio out. The Pre2 DAC offers a sonic step up in performance from our integrated amplifiers. This is achieved because the pre amplifier circuitry has its own power supply. The internal power supply provides isolation from the demands of other system elements making available an additional level of dynamics and resolution. The digital section also sounds better for the same reasons especially when used with the optional Qx card the audio quality rises further still.
