Wilfredt- Sarcher has some Sanders or the earlier version, I forget the name. You might look at his system and ping him. I started with 'stats back in the early 70's and could never find midrange comparable on other speakers, but using the original Quad, I WAS limited by restricted dynamics, bass, beaminess, etc. I used ribbon tweets, and subwoofers, which I could never integrate properly. Still have them, awaiting restoration. Then went to a Quad 63, mod'd by Crosby. That speaker overcame some of the shortcomings of the original Quad ESL, but to my ears, it didn't have quite the same coherence in the midrange. Still have those too. Finally went to horns, circa 2006. Dynamics not an issue, but getting them right has taken time, and they are much more finicky about the associated equipment. At some point, I'll reassemble some Quad stuff, just for kicks (I wouldn't mind doing a slightly updated version of the HQD). I did like that original Martin Logan curvalinear panel and back in the day, listened to my share of others, including the KLH 9 and Dayton-Wright.
Soundlabs probably makes sense. Haven't heard the newest incarnations of the Quad either.
