PS Audio DirectStream Memory Player universal transport

The first time I heard a CD player in my own system was in 1983, the first year of the format's introduction in the West. CD players were generally hard to come by, but I had a friend who worked for Sony, and he came over with his new toy: Sony's next-to-top-of-the-line CD player. (I think it was a CDP-501.) We connected it to my system—at the time, Quad ESLs driven by a Luxman tube amplifier, with a Linn turntable—and listened to some Sony demo CDs.
