Description

Maximum exponent of the traditional technological sophistication of Astell & Kern, the A & ultima SP2000 stands out for incorporating “premium” circuit components and topologies to obtain sound performance capable of competing with those of any reference stationary digital source. Thus, in the critical D / A conversion section we find two AK4499EQ chips mounted in a double mono configuration to maximize parameters such as the linearity of the frequency response curve, the signal-to-noise ratio or the separation between channels, as well as to provide a more spacious and believable soundstage. The A & Ultima SP2000 is also the first Astell & Kern player to use separate and independent audio channels between the unbalanced and balanced outputs, a design that allows it to have unprecedented output power, namely 6 Vrms on the balanced output and 3 Vrms. in the unbalanced output, the result being a listening experience with dynamics perfectly comparable to that of a live concert. Regarding supported file formats, the A & Ultima SP2000 supports bit-by-bit playback of PCM encoded recordings up to 32-bit / 768 kHz and native DSD up to DSD512, in line with its status as a “Hi-Fi” audio player. Res ”of absolute reference. The A & Ultima SP2000 also includes a 5 ”touch screen with a resolution of 720x1,280 pixels, an internal memory of 512 GB (which multiplies that available to date in Astell & Kern models by two and can be expanded by another 512 GB via microSD card, which brings us to more than 1 TB of storage capacity), support for the MQA audio coding system and dual-band Wi-Fi connectivity with a stereophonic antenna to optimize the performance of music “streaming” from networks.
