Mola-Mola New DAC Prototype

Mola-Mola's Bruno Putzeys says that he wants to leapfrog the idea of incremental DAC design and create a product that puts us a decade down the road in one jump. To that end, he was showing off a prototype design that he has working, but not fit into a product yet. He adds that it should be ready in about a year.

The soft spoken Putzeys, from the Netherlands, was stationed in Philip O'Hanlon's On a Higher Note suite atop the Mirage hotel, and handed me a brochure and pointed out some details. "Some things can't be done with off the shelf chips. Today's best DAC chip claims no better than 22 bits worth of dynamic range. Mola-Mola's DAC is designed from the ground up using circuits and digital algorithms developed in-house."

Putzeys said the new design is equivalent to 8xDSD and then suggested those who want to know more check his blog.

Bruno Putzeys is deeply respected in the international DIY community for the quality of his designs and the depth of his thinking, and drew a huge crowd to his talk at Burning Amp. The notion of building a DAC without relying on an off-the-shelf DAC chip is not only valid, but one that dCS has embraced for years.

The very first digital filter I experienced, back in the late 1970s, actually operated in the analog domain, with an array of bucket-brigade devices. The array of shift registers that can be seen on the top board in Bruno's hands works the same way. With each coefficient effectively identical, this behaves as what is called a "top hat" filter.
