They're very close, Sean. The PCM90/91 Random Hall came from the 300 Random Hall, which is very, very close to the 480L. The PCM90/91 has a 20-bit memory as opposed to the 18-bit memory in the 480L. It also has an extra bit in its coefficient architecture. These result in a slightly cleaner sound in the PCM version.
