Maximinus uses a concept called R2R ladder. This is a resistor matrix that is switched for the various output levels delivering a fraction of an internal reference (much like a volume control).
In order to bring the performance of multibit DACs to new levels a very fast and sophisticated switching logic to control them had to be implemented. The result is analog tone and transparency never achieved by legendary NOS Philips or Burr Brown or their modern incarnations or any of the delta-sigma converters. Digital filtering doesn’t like asymmetric signal, but most music is, so the “digital sound” can be switched off on the Maximinus leaving the DAC artifacts to be dealt with via the natural characteristics of our line level transformer. The in-house developed 1ppm precision conversion module takes advantage of the available resolution and bandwidth to present you the whole picture. We have also added what would be expected by any modern DAC for those who insist.
This is a suite of algorithms that would apply digital filtering and upsampling to the incoming data stream. After processing a 16bit 44.1kHz CD data stream it is converted to 32bit 352.8kHZ data fed directly to the DAC. This greatly improves low-level resolution and the sense of space. The process is completely user controllable and can be bypassed for purist and non-oversampling use.
Apart from the uncompromising approach to data processing we have also taken exceptional care with the construction and operation of each circuit within the DAC and to make your investment future proof for new technology development we have provided 2 optional I2S inputs to be used when time calls for it. We have no reconstruction filter at the DAC output providing the cleanest possible output signal.
No feedback loops.
We use a transformer matching the impedance of the converter resistors to the outside world and isolating them from external influence. We use transformer or optical decoupling of all inputs and outputs, meaning that contaminated ground connection and other interfering signals don't make it to the inside of the unit. Each block in the DAC: the Converters, Clock, Input Processing and Control Logic have floating ground planes and our trademark constant current regulator technology. Then the whole assembly is nestled in a solid aluminum case for vibration damping and EMI/RFI screening following the same construction concept as our preamplifiers.
It's a different league from all currently available high end DACs hence the name of a Roman Emperor.

Product History
  • Introduced in 2012 - the Maximinus was based around an MSB Diamond DAC motherboard reworked to use our shunt regulation power supplies and modules with bypassed output stages connected to the special transformer made for us.
  • In 2015 we replaced the MSB modules with our own development further improving low level eligibility and dynamics while still retaining the MSB motherboard as the core. There is no functional or cosmetic difference among the units.
  • In 2019 the Maximinus Mk2 was launched replacing the aging MSB with our own input board handling all digital processing and adding multi format streaming capabilities while the development of our integrated converter board with local oscillators went a step further toward perfection and unmatched sonics. The Mk2 is recognizable by the feature of a color LCD display replacing the green dot matrix and a different back panel design
