vine, I owned and enjoyed a pair of Duntech Princess (older sibling to the SC-IV/a) for 19 years. No problem with the Dynaudio tweeter in all that time.
After John moved back to the US and opened DAL I spoke with him a few times at the Vegas CES. He was an old school engineer and did not believe in "exotic" components. Seeing how complex the crossover was in my Princesses (visual look, I'm not an engineer) I always wondered if better parts might have offered improvements to an already wonderful speaker.
Regarding resurrecting DAL, I can foresee two problems.
The obvious one being the size and weight of most of his models. It seems that trends are demanding smaller speakers. Whatever market that still exists for such large speakers may already be filled by current companies. Also there is how much shipping costs have increased. JD initially moved back to the US from OZ to build a new Duntech model in the US to save shipping costs so it could be priced more competitively. When that failed he separated from Duntech and opened DAL. I offer that only as an example of impacts of distribution costs.
The other problem is potentially what "evolution" in design have you developed? Have you retained John's basic critical time/phase principles? If not then you really wouldn't have a new Dunlavy speaker.
