Description

Astell&Kern's new flagship, the A&ultima SP3000T fuses the best of its illustrious predecessor, the A&ultima SP3000, with the renowned sonic warmth of tube amplification to offer performance perfectly comparable to that of any desktop audio source, with the added convenience of portability. Regarding the engineering details, we must first note the presence of the “Triple Amp System”, which allows the user to customize the sound using vacuum tubes, a digital operational amplifier or a hybrid configuration formed by the combination of both. But what is without a doubt the most outstanding technological feature of this sensational product is the use of two “vintage” military grade JAN6418 vacuum tubes signed by the American Raytheon, fundamental in achieving that tonal curve of unique softness and warmth that characterizes some of the most celebrated amplifiers in the history of audio. In the configuration specifically developed for this absolute reference portable player, the user has the possibility of adjusting the current flow directed to the vacuum devices, in order to make, with the help of Astell&Kern's exclusive TERATON ALPHA technology, subtle changes in the sound “signature”. Finally, we must highlight the extraordinary manufacturing quality, with a body made of stainless steel coated with very high purity silver (99.9%), which provides the A&ultima SP3000T with a classic and modern appearance at the same time.
