Fair enough.
My experience was a bit different. I owned Linn Ninkas and although they could sound very good in active mode, they also had some issues which meant some music was better in passive mode. Eventually I reverse engineered the active XO boards and it showed that they had added 10dB boot at 50Hz (IIRC). I couldn't see any attempt to add BSC. I did try defeating the LF boost bbut that sounded too lean. In the end I concluded Linn had done a very strange "bodge" on the electronic crossover.
In addition to that, in the old days at the Heathrow hifi show I remember being quite impressed by the basic Naim (+LP12) system but the 6 X NAP135 fully active system was very brittle and aggressive sounding.
I now run a semi active system. Active XO between LF system and two way "satellite" speakers which use a passive crossover. This is a very, very good solution.
Sounds an excellent set up - on your figures the Linn electronic crossover does sound a little odd.
I found the Olive generation of Naim, which I had, to major on dynamics, with a very solid/palpable representation of instrumental/vocal timbre - if lacking in tonal colour - but I agree as it could also sound rather brittle and aggressive on the 'wrong' recordings and very flat spatially - an exciting flat wall of sound projected forwards - but not exactly three dimensional.
The latest Naim sound seems to have gone the other way - a lot smoother sounding, so doubtless either less distortion, or at least less propensity to clip easily, much more of a sense of air and space in the sound, warm presentation, with again a good sense of palpable timbre - but still lacking in tonal colour to a degree - but in many ways the famous PRaT seems to have got up and gone, or at least severely toned down.
Certainly compared to my Sony TA- DA9000ES amp, when driving to the same measured SPL levels, one could hear the NAP180 clip momentarily into the SBL's on some music peaks, which surprisingly gave it something of an exciting 'edge' to the sound - but distortion it was nonetheless.
Perhaps this might be the reason that the later Naim amps sound slightly less 'exciting' compared to their arguably less well engineered forebears - sometimes momentary distortion can add a seemingly exciting and tension inducing 'zing' to the sound, but it's only when it's removed that you realise how artificial the effect was.
