Wondering if any folks heard or experienced these class D amps which are pretyy high end
some history ....
Bruno spent nearly a decade honing his skills at Philips's Leuven, Belgium based Applied Technologies Lab before fleeing the roost to chart his own path. At the time, Putzeys believed (and still does) that the future of amplifier design lies squarely in the Class D universe, a perspective apparently not shared by Philips at the time.
Liberated from the design limitations imposed by Philips, Bruno hit the ground running. His first major claim to fame came when he designed the Universal class-D (UcD) power amp module, the subsequent N-Core amplifier modules, and various switch-mode power supplies, all for Hypex. In case you didn't know, Hypex sells these building block components to other audio manufacturers. Hypex also offers DIY amp kits based on Bruno's Class D amp modules for all the Saturday afternoon audio tinkerers out there. The list of firms and products that use Putzeys-authored components includes Grimm Audio, in its AD1 all-discrete DSD analog-to-digital converter, LS loudspeaker range, and related Grimm Audio professional-grade gear; Kii Audio's Three loudspeaker; upper crust amps from companies like MBL and Theta, and down to earth companies like NAD, each of whom utilizes the N-Core Class D amplifier module in their product lines, a testament both to that unit's incredible adaptability and inherent good sound (not to mention outstanding measured performance).
In short, Putzeys may be the most influential audio designer currently working that most audiophiles have never heard of.
