Had a very pleasant hour in Addicted to Audio (Melbourne) yesterday. It's the kind of place I once dreamed of opening - plenty of equipment to try out, courteous and well-informed staff, quiet, no pressure - in short, civilised.
I went there to find out what would drive my AKG K701s better than the amps I currently have and discovered that the start-point would be the Violectric V200. Great control, refined and subtle sound. The Schitt Lyr did not impress - too much FET and not enough tube.
The real revelation was to listen to the Q701, the Quincy Jones version. A-to-A is quite right: these preserve almost all of the K virtues and correct that maddening spike in the treble. Don't mistake me. On well-recorded material I still think the K701 a fine headphone, but anything with a slightly hot treble is tough listening.
Anyone for lime-green?
