The above poster is from Ken Christianson’s listening room at Pro Musica in Chicago. He and John Schwarz have been selling my brother and I British gear for a while. And John, God bless 'im, repaired my Quad 988’s repeatedly.
Ken has done a bunch of True Stereo Recordings for the NAIM Label over time, with a pair of mics and a Nagra recorder, so nota bene, Purist Recording Enthusiasts:
He is also a professor at Columbia College Chicago, hence the educational bent of the above website.
I would like to suggest that anyone who is Axpona-bound this weekend stop in and say hi at the Pro Musica room, which typically is amongst the Few rooms that have both great sound and great music, but sadly, shows are becoming less and less affordable for craftsmen, so they will not be there. They are not the only ones missing.
