I really want to try these out if I ever get a chance. Some of my fondest audio memories involve my old Linkwitz Orion setup with the matching Thor subs. I've spent far more on quite a few speakers over the years, and gotten far less performance out of them.
I also would love to borrow or at less listen to a pair in adequate conditions. Siegfried Linkwitz was an engineer and a scientist, his work on speaker design (mainly crossover and dipole design) and his special care in stereo soundstage should be remembered. https://www.linkwitzlab.com/
If it was not for my long lasting love for the ESL63 I would surely have built a pair of his DIY designs.
