Top notch equipment I'll say!
He was using two Swiss-built FM Acoustics power amps for his live rig IIRC in the 1990s. Even back then these amps, most often used in high-end audio systems or in studios were $20-30K each. Had a chance to hear one when I was writing for The Abso!ute Sound back in the late 1990s - but I didn't review it when the then importer found out I was going to write about it and not then Editor In Chief Harry Pearson. The guy had a hissy fit and demanded it (and its companion preamp and phono stage) back after only six weeks. In '99 those three pieces comprised $80K of gear.
Best solid state amplifier I heard until I heard the Technical Brain amps from Japan at 2010 Rocky Mountain Audio Festival. Those handmade beauties were face-meltingly, mind-roastingly good, as they should be for $62K/pair. Kurosawa-san is a genius.
But no one has ever accused AJ of having anything than the most refined of sonic taste.
