Vincent works as a telecommunications engineer and decided some time ago to develop a second activity in audio engineering. For more than ten years he has developed radio and audio equipment for critical environments like trains, cars, buses and mobile phones. Of course like the majority of DIYers, Vincent Brient has an immodest passion for sound and a religious zeal for zero-concession solutions.
This his own system illustrates quite nicely. Vincent is a qualified engineer and radical audiophile. Due to his telecom expertise he has access to unconventional parts and specific digital solutions. The TotalDac converter is unusual for including parts that are rarely seen due to their excessive cost. Here one plays in the big leagues where direct competitors seem overpriced by comparison.
An integral digital crossover is thus available for those who need to separate bass, midrange and treble feeds for active loudspeakers. Both converter and crossover are available also as electronic boards to allow other DIYers to use their own enclosure. Still, this modular solution could be of interest to solder slingers who simply love making their own or want to go after seriously fancy casework.
While he enjoyed some of them, he was never completely happy with their accuracy. Whenever possible Vincent tested them with and without oversampling. He also listened to many newly minted chips from TI and Analog Device in particular.
This required micro controller programming most of the time. He often considered their sound slightly metallic.

So when I finally laid my hands on it I could not wait to peek inside. That sets expectations high. They got a bulk discount or something? Economies of scale? Is it 8 times better than simple one PCM?
