Soix, it's just the two of us so we're generally should be okay. We have however found that the mix is such that music significantly impairs the vocals. I take your point about the subwoofer but it may be a step too far for the aesthetics.
Pynkfloydd, yup, I'm using ARC into the NAIM today and that's my preferred choice moving forward. It's why the Prisma caught my eye. As for speakers, yes, we're open to upgrading them in time. Blade 2s are very, very pretty. 😏
