Approche jusqu’au-boutiste d'un système dématérialisé

[bubu13]

Bonjour à tous,
Merci à MELLOWMAN pour cette découverte.
J'ai découvert l’existence, il y a peu du PhoenixUSB Reclocker de INNUOS.
La description sur leur site est la suivante:
"The PhoenixUSB Reclocker takes the USB signal from any source and completely
regenerates it to an extremely high-precision signal to feed into your DAC,
allowing it to perform at its best.
The PhoenixUSB offers in one unit the equivalent of 3 separate components: A USB regenerator,
a linear power supply and an external master clock with its own linear power supply.
Innuos applied 3 main design approaches learning from their experience with the Innuos flagship
music server, the STATEMENT:
The USB chip regenerating the signal contains no switching regulators. All 3 independent voltages
to the chip originate from an independent linear power supply with further regulation provided
by 3 sets of LT3045 regulators.
The use of a 3ppb OCXO clock running directly at 24MHz and connected via a board track just
a couple of inches away from the USB chip. Therefore, no precision is lost within cables and
connectors, as is the case when using an external master 10MHz clock with an additional
24MHz clock generator.
Two independent Statement-level linear power supplies, one dedicated to the OCXO clock and
the other used for powering the USB chip/5V USB line".

Il me semble qu'il y a beaucoup de similitude avec la nouvelle carte JCAT USB XE.
Ce boitier est beaucoup plus cher mais il intègre une alimentation 2 rails. L'alimentation de l'horloge et du traitement USB sont séparées!
Ce boitier se retrouve dans leur haut de gamme "le statement" music server.
Si quelqu’un a testé ce boitier? Il me semble que ce peut être une alternative ou un bon challenger de la nouvelle carte JCAT.
