@abd1 I cannot think of a single post from a Nenuphar owner that voices concern over voice! : )

Mike Girardi’s Stereo Times review discusses the performance of Herbie Hancock’s ’Gershwin’s World’ in depth and makes a particular point with Joni Mitchell’s vocals on the recording.

This statement from Mike should allay any concerns you have:

Once you listen to vocals on the Cubes, it’s "Game over" for most multidriver loudspeakers.

My Jim Jordan’s Vaughn Loudspeakers utilized a RAAL ribbon to extend his widebander’s performance. I totally get what you are saying about how RAAL implementations sound. Based on my memory of my own RAAL based speakers (as well as others I have heard), I don’t believe you have anything to be concerned about. BTW, I had the same concern... prior to purchasing the Nenuphars.

My only concern with the Cube’s is how they handle voices. One of my favorite speakers uses a RAAL ribbon tweeter and I love the extension and air without harshness. I know the Nenuphar’s won’t get that extension, but I’m hoping the texture, tone, detail, imaging, dynamics, etc. all make up for it. Has anyone here compared the Nenuphar to a ribbon or berylium tweeter?
Hi David,
At one time I gave serious consideration to Vaughn speakers (RAAL ribbon/Fostex 8" wide range driver) and the Tonian Lab Classic 12.1 (Which utilized the legendary French 12" PHY wide range driver) to pair with my 300b mono blocks. I didn’t know you had a direct listening experience with the Vaughn. Very interesting. David what amplifier were you using with them ?

In my opinion it is very high praise indeed to say you prefer the Nenuphar to the Vaughn with RAAL ribbon tweeter for human voice reproduction. Midrange and vocals were said to be a strength of the Classic 12.1. as well.

Hi Charles,

- Melody I2A3 (Push-Pull 18 watts) integrated amplifier

 and the

- Ayon Spirit II (KT-88 Push-Pull 40/60 watts Triode/Pentode) integrated amplifier

I have fond memories of the Vaughn anchored system. 
Just saw the A/V forum video review from Peter B. on this speaker. Looks promising. I confess not having read through this thread, but the Impedance spec is no where to be found on their website.
