@jonwatches1  Jon, I have not heard Voxativ in direct comparison. I strongly considered Voxativ when deciding on a single driver full range speaker; Holger Adler of Voxativ was a pleasure to engage with and was very helpful. 

In a recent post, @stephendunn makes reference to something that bothered him about Voxativ...perhaps he can comment or you can reach out to him via PM. He has extensive experience with the Nenuphars.

All the best in your choice.

Question: does anyone have experience comparing Voxativ with Cube? What were your impressions?  Thanks!

@ricevs 

 

That is what I thought! An owner posted he wanted to try Vcap Odams in his set? I started thinking perhaps the driver was concentric. Most sorry for my confusion. 

I have been meaning to add a Vcap ODAM in the Nenuphars. I have some on my linear power supply filter caps but I have not done played with it with the speakers. Anyone has any experience on how they perform on speakers

The Nenuphar is single driver and crossoverless. Where would one utilize a capacitor in this speaker?

@jonwatches1 I auditioned the Voxativ Hagen speakers with a Voxativ sub driven by a Voxativ tube amp on three occasions--separate listening sessions at the same dealer, same set up. This was maybe 4 years ago, long before I had ever heard the Nenuphars, so it is obviously not a comparison. What bothered me at the time was an initially very attractive sound that I found fatiguing after about 20 minutes or so. I brought my own material in to play, same result. I found the highs to be forward and irritating on a lot of material. Could have been the digital front end (I don’t remember what that was), room, cables, etc.
