Dennis is, of course, continuing with his well respected trait of unrestrained humility regarding the quality of the cabinets being sourced for his designs. His business partner has clued us in that the factory producing their cabinets also does cabinets for other high end customers as well.
While I would love to know some of those who source there cabinets from the same facility, I respect the privacy required as well.
I think the mere fact an affordable high end design can be sourced from a manufacturer in another country is just fine. I don't mind a Chinese cabinet if it makes the difference between a pair of Speakers selling at $4K per pair vs 2.5x that for US labor.
Whether PS Audio is sourcing their cabinet build from China, or the whole Dim Sum Bar, their Speaker should still be judged on the merits of performance vs price to consumer.
For me, even if the cost to performance ratio favors the consumer (as it well does with Dennis' Speakers), the asking price is still far too high for me to be willing to consider. Unfortunately, I expect to find the opposite in that PS Audio will be asking far too much for a bucket that barely holds water, and they can go jump in the same pond as Wilson Audio with that.
Maybe they'll still rake it in, and more power to them for that.
My money stays with Dennis.
