Linn amplifiers are pure Class D. They are not hybrid. They name everything, the power supply is called Dynamik and the amplifier Chakra.
The system I owed was their original version from 2007. It was a bit cold and unengaging, which rather put me off pure Class D, although it has been significantly improved and you can upgrade the power supply without having to change the whole unit.
Linn are one of those companies that like to make as much as possible in-house. This new DAC design looks interesting, there is a fun animation, but I can’t say I really understand it.
I just looked at their last annual results. With sales of $25 million (all to dealers, none direct), they spent $4.5 million on research and development, plus a further $0.5 million on new plant and equipment. They basically put 90% of their profits into R&D. The R&D team is 32 full-time staff. That seems an awful lot of research for a small audio company. I wonder how that compares to PS Audio.
