The least that can be said about the ultra-compact A & SR25 standard is that, for the price at which it is offered, it is nothing short of groundbreaking because, among other features, it supports digital files encoded in native DSD up to DSD256 and PCM up to 32 bits / 384 kHz. , a feature until now reserved for the elite of Astell & Kern. Added to this is the new “Performance Mode”, which automatically adjusts the memory according to the size of the file being played to optimize the sound quality. Logically, the correct reproduction of high-resolution audio files such as the ones we have just mentioned requires a very high-performance management processor - a quad-core design to be exact - and an extremely fast memory access speed, as well. as an appropriate signal path to process the relevant signals. When it comes to connectivity, the A & norma SR25 includes balanced and unbalanced analog outputs and a USB-C input (for charging and data transfer to PC and Mac computers), plus high-resolution wireless connectivity via Bluetooth. aptX HD and LDAC. The icing on this impressive Astell & Kern player is an all-aluminum construction executed by an ultra-sophisticated five-axis machine tool identical to those used in the Swiss watch industry.
