Nice comparison with the Quads. I guess I am a bit sceptical regarding the Super 7 being as revealing and transparent as electorstats. I would see it more like a Maggy in that regard.
The neo 3 is a great, natural, non fatiguing, tweeter, but for me, not the very last word in detail retrieval. So I would expect the same with the mid drivers. Still very good.
Steve, if you had an active crossover and the desire, it would be interesting to try the Super 7 woofers with the Quads. I know, that's a bit of work and we just want the music, ha. BTW, how is the image height on the Super 7s?
