 When we were brainstorming the ideas, we used to start with the whiteboard in terms of one through identity as a market requirement. We'll start with the whiteboard and then we'll get the products team together. And on the surface of it, I think we wanted to use our existing digital platform, which we've used since ID Series, Silverline, ID Core. And we already have a lot of expertise in valve and solid state power amps. So on the surface of it, putting the two things together was made sense because it shouldn't be too problematic. But I think putting together something very loud, great sounding, that's very reliable and robust in such a small package that actually became the biggest challenge of all. Thank you.
