I spoke to Tash Goka (owner of Divergent Technologies & former North American distributor for Antique Sound Lab) a few years back and he said that Antique Sound Lab was no longer in business. Perhaps he meant that Joseph Lau, owner of ASL, has decided to get into another business. I still own my ASL Wave 25 tube monoblocks as well as my ASL MG Head DT headphone amplifier, now 21 years old, and enjoy these audio components very much. Antique Sound Lab was a force to be reckoned with in the world of hi end audio back in the 1990's, and much of the 2000's, receiving many awards for their outstanding products. Including a few from The Absolute Sound audio magazine.
I was sorry to learn that they are no longer selling products in North America.
