I absolutely loved the 40.2. It is all that midrange and added gorgeous bass. Full and natural sounding across genres. I can imagine the 5/9 or 30.2 sounding less satisfying when you listen alongside that. Perhaps that is what jriggy heard?
The Super was not my cup of tea in both the situations that I heard them. Yes more bass than 5/9 series (a rose by any other name?), and had more punch, but did not sound as beguiling in the midrange. However, admittedly there were variables, and they are really nice speakers - to summarise, not on my wish list even if there was a sale.
40.2 or do I need that extra kidney?
The Graham series is indeed expanding as captainblood said. 5/9f 5/5 Etc.
