Cons - Require Recabling and Specific Amplification
Well, I have tried all of the great headphones over the last few years (Stax, Sennheiser, Grado, AKG, Audeze, Beyer Dynamic, etc.) and I have returned to my all-time favorite K1000s with Stefan Audio Arts Equinox cabling - driven by a Macintosh C2200 tube preamplifier and a First Watt F1 amplifier. What brings me back is the incredible soundstage, the imaging and the transparency of the sound. I no longer listen to the system - I listen to the music. What more could I ask. I am re-listening to my entire music collection with such appreciation for the incredible performances. I am really happy with the K1000s in this configuration. Of course I will keep listening to other offerings (it is a hobby after all), but it will take a lot for me to switch from these great "earspeakers".
