The Nenuphars are so easily driven it seems that the beastly Aries Cerat amplifiers would be overkill in this specific application. I’m not doubting the sound quality of these  massive amplifiers.

Thanks for a very educational thread.  I don't know if this can be answered directly, but feel free to speculate.  How much of the loudspeaker's sound quality is attributable to its full range, crossoverless design vs. its fanatical and over the top construction?
I am quiet happy with the SIT-3 (both sound and power-wise) and am thinking of either investing in a better preamp or a good tube integrated. The VR L2i at $19k is out of budget and so is the AC. Has anyone paired a good integrated at a reasonable lower price, say 10K or somewhere in that range, give or take ?

I'm not sure whether it was in this thread or somewhere else, but I read that someone was very happy pairing the Nenuphars with the Line Magnetic 845 Premium integrated.  Actually I think several in their line would make good mates--damping factor won't be an issue, but you have to look for their circuits with no negative feedback.  Price wise I think you're looking at $9-12K but don't quote me.
Onhwy61,
Well, david_ten who has owned the Nenuphars for a couple of years could certainly chime in with some informed insight. Based on what I’ve read and heard about this speaker I’d say that probably 70% is attributed to the remarkable driver’s exquisite design parameters and its successful execution/implementation. Many hours and tedious effort along with extensive trial and error were required.

The speaker cabinet dimensions/geometry/physics and chosen material and construction technique probably account for the remaining 30%. If you carefully read the original 6 Moons review you will appreciate there was major effort needed to get the cabinet right. I believe that the cabinet plays a large role in the final sound quality that is not given suitable credit for.

The driver and motor/magnet assembly is an outstanding end result and would work beautifully in other DIY cabinets ( If well thought out ). But without question the special Nenuphar cabinet is a crucial aspect for this speaker’s resounding success. A ton of talent, effort, knowledge and patience went in to getting the Nenuphar right.
