Does Quad still make a DAC or some Quad-like equivalent? They love to make CDPs and preamps with digital inputs. To this day the most "musical" DAC I've ever owned is my Quad 99 CDP-2 (which is now so old it'd be a senior in high school.) Looking at their website, they have an "Artera Play+" model which appears to be a CDP with six digital inputs and USB. That sounds like the Quad I know and love, batshit insane but with a real beauty mixed in with their quirkiness.
The original Jecklin Float Electrostatic headphone wasn't much chop sonically - yes it had vast, bright dynamics, but at the expense of no bass whatsoever. Also, no-one in their right mind would wear these anywhere near a camera.
They didn't hold a candle to any version of the Stax Sigma or Sigma Pro and so they were sold.
The original
....and the reconstruction
Some trumpet player or other with his home hi-fi (I'm not sure it was stereo) in the late 1960s. Photo most likely taken by Jack Bradley. I'd love to know the identity of the trombone player. Google has, and I want to be clear about this, utterly fucking useless in this regard.
