Not at all. It was a Stax headphone, not expensive. It was the head amp. Bought them used from my hi fi teacher for a bit over 1k USD for both, was a good deal. Head amps are always expensive. I remember the first moving coil cartridge I had was Ortofon MC20, which was not expensive, but the head amp alone was five or six hundred USD back in early 80s. (JBL 4311 3way, 12in studio monitors were about $400/pair USD, disc price).
Lucky, you are not into heaphones...me either, bought them for show when I was young..I don't really use headphones much....Stax are very expensive headphones..LOL...
