If a 303 will drive them I'd have thought almost anything would?

I would suspect the amplifiers; despite what looks like the use of four monoblock units. NVA amps have never been included in a short list of amplifiers that will work optimally with the the Quad ESLs.

I think you could be right.

All Quad amplifiers were designed specifically to drive the Quad electrostatics, as well as conventional speakers.

Although the 303, along with all other solid-state amplifiers of the time, used an output coupling capacitor, the value was carefully chosen so as to resonate with the inductance of the Quad ESL input transformer and extend the low frequency response.
