I had old school Levinson equipment 380S, 390S, 335 amp. All great in their day.
But, when they need repair, very restrictive ( limited factory repair depots) now and very, very expensive. I saw a thread on here a while ago that to reburbish a CD player was over $3000.
I gently moved away from them.
In fact, I got my back up when they started putting radios in Lexus sedan/SUV. That was the beginning of the end of my love them. HK really ruined their high end reputation in my eyes/ears.
