Van Den Hul amps and preamps


I saw an ad for the above being offered at a closeout price. The amps appear to be full class A but there was almost no information on the site. I have never seen these products, what is the story?

Is this the site where you saw the ads?

At the bottom of the page, there are some links to Van Den Hul reviews.
I saw those but wanted to hear from actual users.
