Mg123,
I cannot find anything indicating lack of warrantee transferrability on the Madrigal/Harmon Specialty Group website, or on the Mark Levinson or Revel web pages. Also, many here on Audiogon are still advertising gear for sale with the balance of the warrantee remaining.
Having said this, where did you see this? As for my sources, they are under the impression that warrantee is still transferrable, as it has been in the past.
Regarding this subject, concrete information would be appreciated by anyone in the know. Thanks in advance.
