@mapman , I got sick and left early, couldn’t go back the next day to bother him with questions.
This is the closest to a tad reference (which I had for almost 15 years) he’s gotten to yet, i think, in many regards. But, I believe it has some variant of the Elac Adante style bass radiators, don't know the exact details or intent.
The TAD probably has a bit more soundstage sprawl, but, this one hits like a mack truck, more muscular, if needed.
i don’t know the intended pricing, but, has to still be a fraction of the tad’s price.
