Coincidentally I demoed these today also - also just for kicks, as I'm delighted with my current speakers.
My experience just goes to show how each have their individual tastes! I heard them through electronics superior to mine but with which I am familiar and also playing my own music, in particular one of my favourite albums 'Blue Skied An' Clear'. If I didn't know my 40s so well I expect I would have been extremely impressed by these speakers and certainly they are 'fun' and I can imagine many people purchasing. Stereo imaging was also a plus.
However, as well as 'lacking the bottom octave', I found that the mid to lower bass was rather blurred and inaccurate, and that this in turn had a knock-on effect on the mid-range, slightly veiling in particular female vocals. I also found the treble timing slightly off, with transients being a little 'splashy'. Overall, it made me realise what a good test CD this was, with the kit needing to excel in separation, detail, timing, transients and bass speed and texture to show it off well. I should say the speakers were pretty well run in.
None of that's meant to upset anyone who's a fan and as I say I'm sure they'll make a lot of people very happy. But for me, they made me absolutely delighted with the qualities of my 40s 🙂
