Astell&Kern’s newest audiophile providing comes with a premium worth because of its 98% copper physique. The SP3000T Copper Version options the identical moveable audio participant that creates a fusion of the very best of each worlds for an analog and digital audio expertise—now in copper.
Astell&Kern’s SP3000T options the mixing of an actual vacuum tube to create an genuine analog sound, complemented by cutting-edge audio know-how akin to Teraton Alpha for an immersive auditory expertise. This moveable audio participant options twin Raytheon JAN6418 Mil-Spec classic vacuum tubes and a triple amp system to permit listeners to pick the appropriate tones for his or her music. The result’s an audio participant that options separate digital and analog sign processing.
The Copper Version takes that one step additional with a physique constructed from 98.8% copper. Copper is thought for its glorious sound transmission and resonance properties, enhancing the brightness and richness of musical tones. Astell&Kern has created a specialised multilayer coating that enhances sturdiness to assist this limited-edition audiophile accent preserve its lovely luster with out oxidizing or requiring particular upkeep.
As a consequence of variations in noise and amplification amongst unique vacuum tubes, Astell&Kern have created a meticulous course of to deal with minute variations in sound high quality. Astell&Kern fastidiously measures and pairs every JAN6418 vacuum tube to attenuate deviation between the left and proper channels—leading to a extra pure sound replica.
The SP3000T options an impartial modular, versatile PCB design engineered individually from the primary PCB. It has a silicone module case designed to soak up major shocks from the vacuum tube, with silicone tubing completely tailor-made to the vacuum tube to cut back shock transmission alongside the leads. Lastly, it options silicone dampers across the vacuum tube to droop the tube within the air from each ends—serving to to eradicate microphonic noise.
Attaining these low noise ranges withing the compact confines of the SP3000T physique was no simple problem. The machine homes two of AKM’s newest flagship AK4499EX DACs and a separate audio circuit design with the AK4191EQ—which is utilized independently to the left and proper channels chargeable for processing digital indicators.
With this distinctive audio circuit configuration, the SP3000T reduces the noise of the enter digital sign, whereas performing as a separate digital delta-sigma modulator. Solely analog indicators are processed inside the DAC AK4499EX, making certain digital and analog indicators are processed individually.
