not a bad wish. need to go full active then.
BTW esteemed ASR member
@mocenigo joined a casual after show hours listening on the Spk16 with latest tweeter and 9040 amps. Maybe he can offer a testimony.
I already did

Of course all caveats apply — the room was far from perfect, and most the rooms at the Munich Hiend were actually even worse, at least that was an actual room and not a temporary cubicle or a room under a tilted ceiling, so comparisons cannot really be done etc etc.
But I want to underline
one aspect, there was nothing spectacular except ... for the way it sounded natural, and also in non-centered positions.
That was, in fact, spectacular. It seems that Lars Risbo and Carsten Tinggaard's idea of a good speaker and mine are similar: wide dispersion, wide and flat extension, no range emphasized in any way — resulting in an "unspectacular" sound with a relatively large sweet spot. I designed my own speakers following similar principle. I do not claim to be as good as Lars and Carsten, maybe I am better

(LOL, no).
During the last few years I already heard a couple of iterations of the SPK16 (first with the little AMT, then with the Purifi tweeter prototype, and now with a pre-production of the larger waveguide) and each version improved on the characteristics I appreciate. It sounds the way I want my speakers to sound.
If you prefer hyperanalytic sound in a tiny sweet spot where you cannot move your head without hearing artifacts, then this is not for you — I understand some audiophiles actually prefer that, esp. if the treble is emphasized.
As for the amplifiers, well, the 1ET9040BA is a second generation Eigentakt, I am sure it is technically better than my 1ET400A build, but I doubt I would be able to hear differences, either with the SPK16 or with the three top ways of my speakers. I would probably only hear less hiss when in immediate proximity to the woofers of the ripoles since I am driving them separately with a Hypex Fusion amp and the gain must be very high. But in any case I would probably not use a second pair of 1ET9040BA's to drive them. — Of course I want it (and the new discrete buffer!) but my wife would kill me.
