Found this thread because I'm very seriously considering the qualio iq. It seems to have everything I'm interested in from a technology (and expected behavior based on that tech). I've been interested in cube as well but haven't auditioned yet. I'm going to go listen to some nenuphar mini that aren't too far away as I expect that will give me an idea of what the IQ will do in the mid range. I am 100% confident the soundstage and imaging will make me happy based on the video they posted on YouTube (played through dartzeel and reference 3a speakers, the only thing I can really determine is soundstage imaging and dynamics but what I hear confirms what one should hear with this design). What I'm concerned about is mid range and vocals, coming from harbeth I'm picky about that and trained to really appreciate warmth and life like timbre. If the cubes make me happy in that regard I'm going to order. The price is fantastic even including shipping taxes and duties.
