• Introducing the Model 625

    The Model 625 features a unique composite circuit architecture incorporating separate Class AB voltage and current gain blocks with no overall negative feedback.

    Virtually free of internal and external EMI field contamination and mechanical vibration, the Model 625 delivers a sensuous grain-free musicality of unparalleled transparency and low level resolution.

  • The making
    of Model 625

    Machined from a single block of non-resonant aircraft grade aluminum, the beauty of the Model 625 chassis is the product of the experience and talent of Vertec Tool in Colorado Springs, Colorado.

    Go behind the scenes and see Vertec's artistry at work.

  • Discover the ‘Science of Silence.’

    It is from the depth and richness of the silence between the notes that the genius and emotional content of music truly emerges.

    Achieving this ‘living silence’ requires a perfect synergy between science, technology, and experience.

    Introducing the Aeris DAC

    An idea conceived over drinks at the Munich HIGH END audio show, the Aeris DAC combines over 25-years of analogue audio expertise with the best outcomes of a six-year interdisciplinary digital audio development project, resulting in DAC technology so bold, so natural, and so musical, it may just violate the prime directive.

    Based upon an asynchronous buffer, voltage controlled crystal oscillators and a 24-bit D/A converter – under the precise control of a FPGA running proprietary algorithms – the Aeris DAC delivers bit perfect conversion and reduces total jitter to less than 10 picoseconds RMS from any input.
