Duelund CAST silver a $50,000 Upgrade?

Hi Berkelyaudiogeek

Don't worry about this time aligned first order crossover thing. I know a speaker maker who built two speakers identical in every way except one was first order time aligned and the other not. He could detect nothing - nada - from the exercise. He has however found that phase coherency through the crossover pass-band was important and uses a third order quasi crossover to do that.

My advice is not to worry about that sort of thing and judge a speaker by what you hear not how they do it.

Thanks

So no one out there can explain the huge difference in price from CAST copper foil to silver? It surly is not just the metal.

As far as I know the Deulund CAST differ only in choice of metal foil used.Other than that distinction all else is identical.

then why is silver 12 times more $$$

It's not. I suspect your speaker manufacture decided they didn't want to bother with yet one more option that would need to be purchased and tested before responsibly selling. Sounds like they just pulled the number out of their rear to make it go away.
