To those of you who missed it, here is a link to the live chat with Lars Risbo of PURIFI Audio. Lars provided an overview of how drive units work, insight in to what makes PURIFI drivers so exceptional, and an exclusive look in to the hardware and software used in their R&D work.
I know I speak not only for myself but the community as well when I say "thank you" again to Lars and the rest of the PURIFI team who helped facilitate this and offer some insight of their own via the chat. Maybe we can do this again in the future.
