Naim amplification with quad ESL

I used to be a Naim owner in the 1970’s & 80’s, (22 – 120, 12 – 160, 32.5 – Hi-Cap – 250) I know that Naim said not to use with Electrostatic Speakers.

I tried one of the small Naim Pre / Power combinations on a pair of Electrostatics in the 1990’s (not Quad’s), the Power Amp closed down in less than one minute)

I do not know when, or if this changed. I would not try unless I contacted the Naim Factory with Serial numbers for their opinion.

Strange really because Naim were trying to manufacture a full range Electrostatic Speaker, I heard a prototype, very, very impressive.
