Nice comparisson! I dont know if I would like the wireless version but I do like KNA pickups. The Aceto pickup is nice but there's more of an electric sound. Maybe better for jazz (or further sound design= pedals) but kna is more acoustic right away. Downside is it's very "visible" and the ISI is better hidden under the chinrest.
Thank you for sharing your opinion! 🙂 I haven't noticed any delay, but unfortunately, the signal sometimes drops depending on my position. This can be a problem when moving around while playing.
