I was a proud owner about 25 years ago. I actually sold a Mac 275 tube amp for it. (I know, I should be horse whipped for that audio stupidity.)I was in love with power at the time.
I remember that period in time very well. Amps were going for power and very low IM and THD distortion values. A Finish engineer by the name of Otela came up with a new measurement about then called Transient IM distortion. This was the first insight into why tube amps actually sounded better than solid state amps, like the PL and Crown DC300.
You could call the Phase Linear 400 one of last of the high TIM beasts. I can remember listening to them. They sounded impressive with all that power but when the music got loud they turned diamand hard.
