MU2

We are convinced that smart integration of functions yields higher audio quality. The MU2 combines a music streamer with a superb DAC and a reference quality analog pre amp. Its built-in DAC takes full advantage of the Grimm Audio low jitter clock and high performance FPGA processor. A relay based analog volume control enables the MU2 to become the true ‘hub’ of your hifi system for both digital and analog sources. Just like with its sister product, the ‘digital output’ MU1, a Roon Labs server is on board so no external computer is needed to enjoy perfect streaming.

PW1

For the PW1 “Phono Wizard”, Peter managed to develop a solid state phono preamplifier that matches his best tube based designs. Peter believes that designing a good phono preamp is not about achieving the lowest possible harmonic distortion as an isolated parameter. He searches for an elegantly minimalistic circuit design in which he optimizes the ‘electric environment’ of all the active components, in conjunction with a meticulously tuned power supply. Needless to say that passive components like capacitors and resistors are carefully picked.

LS1c

The LS1c is the flagship of our LS1 active loudspeaker series. It is named after the revolutionary TPCD Carbon Composite tweeter that we developed in cooperation with driver manufacturer Seas. Even more important is that we rebuilt all elements of the LS1 design from the ground up: the electronics with latest generation amplifiers, the audio DSP code, the computer aided calibration method, the firmware and the PC/Mac software that controls the entire system. To pick just one example, with the knowledge we gained from developing the MU1 and MU2 FPGA Pure Nyquist filters, we were able to dramatically improve the crossover phase correction filters of the LS1c’s DSP.

SB1

The SB1 with ‘DMF’ is a technological marvel. By applying ‘Digital Motional Feedback’, a control technology from the renowned Dutch high-tech industry, it became possible to achieve exceptionally low levels of distortion and full dynamic control. With an SB1 added for the bass frequencies, the LS1 system offers low distortion over the full audio band and redefines the term ‘transparency’. This is bass control like you’ve never experienced before.
