V1 and V2 back and forth. It takes 2 people only a few minutes to change the drivers.  And yes, it’s my personal judgment 😎

Btw, when prompted, Srajan preferred the V2 (scroll down few letters till you find the one on Nenuphars V2)

Yes he did and I’m not disputing that at all. If my reading of his review was accurate, he seemed to imply changing to the v2 drivers might very well necessitate changing current components in one’s audio system to match properly the v2 signature/character.

Your comments suggest that this may not be required in all v2 driver swaps. It is rather system dependant. Some v1 owners ’may not experience the brightness that you occasionally heard. Those with different source, preamplifier, amplifiers may feel that they have sufficient "meat on the bone " fullness already. That is my only point.

Thanks Toetapaudio.  Charles, fair enough.  That’s why I shared what my others components are so you can get an idea of my starting point & preferences.  Between us I was perfectly happy with V1… with V2 I am just happier 😁

To put things in perspective, if you have a pair of Nenuphars the single biggest upgrade you can do is to add their active Sub 12’’ (or two if your room is larger than 50sqm). Srajan has spent a ton of pixels on the many advantages of such a combo, I can witness that the impact on SQ is an order of magnitude higher than the difference between V2 and V1

Are there visuals on the process for swapping the drivers? Guessing you just remove some bolts for the existing driver, carefully remove it from the cabinet, unplug the wires (assuming its a plug and not soldered), then reverse the process for installing the new driver? Guessing the drivers are fairly heavy with all of those magnets.
