Audiophile all the way


Needless to say that we selected the components for the Decade with utmost care again. Thus, for instance, the employed input stages ensure an amazingly low-noise reproduction. It’s not without reason that they can also be found in very high-grade mixing consoles and microphone preamps from makers of professional studio electronics. The ultra-precision passive RIAA equalisation network lies between two linear gain stages and is realised using low-loss precision MKP capacitors. That way transients, dynamics and sonic timbres will get straight to the listener in a genuine manner.


Always with your musical enjoyment in mind, we have also developed the PWX II power supply which lets you benefit from a further enhanced performance. This power supply that is equipped with inductive elements at critical points feeds the Decade with very low-noise DC voltages. Like in the Silver Cube it is linked to the audio device via a shielded cable with Neutrik connectors. Since the PWX II power supply is downward compatible with the PWX power supply, the audio devices of the Black Cube series may be connected as well. For this purpose we have provided a dedicated second output.


Focus on versatility


Of course, with its manifold setting options the Decade, too, is fully custom-tunable to your individual needs. Thus e.g. even exotic MC systems can be connected hassle-free to this outstanding phono stage – the 66 dB maximum gain is definitely sufficient in any case. To give even the most exceptional MC system a matching termination, we have included a free slot for a custom impedance. Furthermore, you have the possibility to individually adjust the input capacitance values. The discrete class A output stage with its high quiescent current delivers an open, swift sound image and can easily drive longer cables as well.
