<<I thought it would be interesting to know what speaker cables you are liking with the Nenuphar’s?>>

I've used three types. In order of preference:
Ansuz
LessLoss
Stealth
Of course the amplifier plays a significant role as well.

rwpollock I am happily using Shunyata Alpha v2 speaker cables.

The Case for Base

Over the past few weeks I've been auditioning a KEF KC62 subwoofer with my Nenuphars.  I did this not because I'm a base head or because I felt the Nens lacking down there, but simply out of curiosity (and the positive feedback of others who have added a sub or two) and the fact that KEF offers a 30 day return.

But, spoiler alert, I won't be returning this remarkable little subwoofer.  I've incorporated it to have such an effect that I have to admit I had no idea what I was missing.  And it's not slam pounding my chest at 95 db but the overall added musicality, a rich foundation which, when the sub is off, makes the Nens sound unbalanced, almost thin (I know, hard to believe, but that is the impression when one is a/b-ing).  To use a b&w photographic metaphor, I was missing the dark shades of grey through to pure black with the Nens by themselves.  There is now a foundation to the music that was meant to be there and was missing.  The real test for me were simple acoustic recordings with stand up base (read Charlie Haden with anybody) and one or two other instruments.  With the KEF sub dialed in properly, bringing the base forward in a tuneful yet solid way, these recordings had more presence, involvement and reality.  As if their true balance was restored.  And of course the same held true if not even more so for music with bigger base, rock and orchestral, etc.    

Obviously I'm a new comer to the sub party and there are no doubt better applications than adding one ten inch sub woofer, but my room is fairly small and this tuneful gem is doing the job to my great delight.  BTW I did the sub "crawl" thing to find the best location, which oddly turned out to be right next to my listening chair. I use the 60db crossover and not quite half volume.  No muddying of mid bass or any other downside I can hear.  Fun stuff. Brings the Nens to another level of enjoyment.
rwpollock - which model Ansuz cables are you referring to that you place as your first preference.

I have C2 level Mainz Power Distributor and C2 Mainz power cables. Have always been tempted by their speaker cables but seem to think (from what I've read and researched) that their power products are the sweet spot in their lineup.


Re the Ansuz cables, I have a set of D1 which, given the improvements from the 1 generation to the 2 generation, may be equivalent to the C2 level. Agreed that their power products are the place to go; I bought their other wires in a package deal I couldn't refuse from someone who was upgrading at the time.

At a lower price point I would certainly recommend the LessLoss products; Atelier 13 in Nashville offers a loaner two-week home trial. The package contains an assortment, but once again power is the ruler.

BTW I should make clear that my previous post regarding sub woofing the Nens is not meant to be a blanket recommendation to do same.  My set up puts the speakers far from corners, sidewalls and front wall (to emphasize breadth and depth of soundstage) and my ceiling height is over 20'.  So there is little ambient base reinforcement which accounts for the KEF KC62 making a more positive impact than it might in another set up.  And I meant 60Hz not 60db for crossover.
