An evolutionary successor to the widely popular SP3000, this model combines the peak performance of its predecessor with the unmistakable warm sound of a tube amplifier. At the heart of the SP3000T are two vintage vacuum tubes that form part of an innovative triple amp system. This system, originally introduced with the SP2000T in 2021, allows users to customise their listening experience by choosing between tube amplification, digital amplification or a mix of both to suit their personal preferences. The SP3000T's tube amplifier technology produces a warm and inviting sound reminiscent of classic tube amplifiers.

The hybrid amplifier mode harnesses the strengths of both worlds to create a new sound quality that combines the fine analogue nuance with the precision of digital output. An outstanding feature of the SP3000T is the strict separation of the digital and analogue signal paths, made possible by the use of AKM's latest high-end DAC, the AK4499EX, in combination with the AK4191EQ, a dedicated digital delta-sigma modulator. This innovative architecture results in unique sonic purity by minimising digital noise. The operation of the SP3000T is ensured by a Snapdragon 6125 octa-core processor and 8GB DDR4 RAM, which ensures smooth and fast operation. The stainless steel housing with a 99.9% pure silver coating emphasises the classic design and harmonises perfectly with the vintage tube amplification de.
