Lots of what I just read in this thread is old horror stories, some are even true. Harman has shuffled things around more than once in the last several years.
But Levinson Lexicon Proceed service stabilized years ago after High Tech Masters was let go. Turn around is reasonable if not good and we can make the equipment more reliable than ever.
For example some of the No33 were known to have buzz in the speakers. We now know the massive transormers leak enough flux to be audible in a speaker NOT connected to the 33. just loop the speaker wire around the 33. similarly you can loop your wires around the the 33 and cancel the internal buzz picked up. NO BUZZ
