Full-featured Network Music Player/DAC/Preamp
Class-A triode vacuum-tube output stage for single-ended & balanced operation
Signal Path
We believe that the simplest circuits work best together with the shortest signal path. That is why our pre-amplifiers to date have used single-ended pure class-A circuitry. The shorter the signal path is, the less possibility of sonic degradation from various sources, including the wire itself. Even on the circuit boards, the copper traces are kept to a very minimum length. The completely redesigned circuit board provides a more straightforward and direct approach to the signal paths.

Power Supply
The power supplies have been further refined with new components and enhanced AC line noise filtration. Separate power transformer windings and filters provide total isolation between the input and output stage which makes this a pure power source and it is a critical attribute for a 6H30 output stage. We also use electrolytic capacitors with much larger storage capacity to make up for the loss in filtering when using resistors in lieu of inductors.
Dual R-Core / Low noise – insulated power transformers for digital & analog separated
Innovative power supply provides a high speed energy delivery on transients
Separate and isolated power supplies over each stage of amplification
AC power line filter to avoid noise and hash from entering into the unit.

Components
The type of parts used therefore must have a synergistic relationship to the circuit they are placed in. It is this relationship of which type of part to use where, that ranks our products apart from the mass.

Vraisemblablement, un vrai concurrent pour le LINN Akurate DS et DSM. 
Va comprendre pourquoi... 
Mais parait que c'est pas génial sur les DAC au niveau son. Je dis ça mais j'ai jamais essayé 
: désormais on peu utiliser un LINN DS comme une carte son externe (donc comme un DAC USB). Il est ainsi possible d'écouter de la musique directement sur PC, par exemple J RIVER, FOOBAR, même directement sous YOUTUBE et autres lecteurs vidéos.
