They are said to actually return to production with assistance from Arthur Janszen’s son, David who currently refurbishes the originals.I still have a pair of KLH Nines in use. A one-owner pair I bought in 1992 from Hi Fi Classics of Far Rockaway, NY. $500! Have them connected to a Carver TFM15. Am planning to use my restored pair of Futterman H3AA's with them!
