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.
