I've decided to give the Caldera a second shot.
Hoping that my current chain will serve it better than my last.
Maybe this time I will have that "ah hah" moment.
Still love my Calderas very much. These are just wonderful headphones. They also respond very well to changes in amp choice. Which one did you use before, and which one will you now be using?
one more note - there's an unusually high selection of pads for these headphones which change the sound profile quite a bit. Get yourself 3 pairs or as many as you have patience to test, and play around with them (thogh suggest couple of weeks patient burn in to start before getting the base line set).
enjoy!
