I’m just getting acquainted with Aries Cerat and never tire of seeing lids-off photos of AC DACs and pre-amps with their shiny rows of transformers, capacitors and tubes neatly lined up like a giant heavy metal chessboard. Queen E280F? Then I recently learned where the USB input circuit was located, this relatively tiny blue card, seeming to float above the battlefield below. You have to be impressed with the contrast… and the design, when you realize how simply the USB card could be removed and a new card for an updated input protocol plugged in instead. No need to send the DAC back to Cyprus. In audio design, like chess, it’s wise to think a few moves ahead.
