All of the following 4 units have spent auditoning time in my rack. My SCD-1 was the slow......est for the TOS to load, you could watch the leaves on the tree's go thru a change color before the first track would play! The Sony scd-333/555 5 disc changers are the fastest of the Sony ES Sacd stable. The Philips Sacd-1000 was the fastest, yet sound quality wise it wasn't up to par w/ the Sony's.
