Infinity Servo Statics 1-A's....???

OK all you out there with great memories.....I've been looking for a "working" pair of these speakers for quite some time with no luck. So I saw another thread the prompted to ask.....if anyone remembers this speaker what would be the closest to it today? Martin Logans CLS's with and 18 woofer? Soundlads M-1's or M-3's with a woofer?

Suggestions?
