Pour la partie PCM, je suis d'accord (j'avais d'ailleurs écrit dans le premier message qu'il y avait dans ce cas huit puces Burr Brown).
Pour la partie DSD, voici ce qui m'a fait écrire cela (extrait du site de T+A):
Our T+A True 1-bit converter is unique, as it forms a break with a paradigm: conventional converters process DSD signals by converting them into PCM, and reproducing them using the PCM mode. But this conversion contradicts our principles, and caused us to develop the True 1-bit converter, which processes DSD files in their native form, without detrimental conversion processes, and reproduces them in totally pure form as genuine 1 Bit Stream.
Our PCM Quadruple Converter features a double symmetrical circuit design comprising the eight 32-bit Burr-Brown converters, thereby providing above-average compensation for non-linearities in the sound, and reduces the already minimal background noise by a further 6 dB. This sophistication results in amazing dynamism and linearity combined with an equally amazing freedom from distortion. Although we believe in unadulterated music reproduction, the Bezier filters - another in-house development - in the quadruple converter can be exploited by the listener to fine-tune the sound characteristics to his individual taste. The application of polynomials results in perfect timing behaviour for each of the six available filters, two of which are NOS stages.
