The Cambridge transport drawer gave me trouble, either sticking shut (had to band the transport to get the drawer to open) or not reading the CD. These were infrequent problems, but sufficient to cause worry.
I'm both handicapped and retired, so my music is a principal enjoyment in life. I figured that the BCD3 would solve a couple of issues, viz., the drawer and needing the space, power and cabling for the BDA-2. Also, I wanted the capability to place the spinner on disk repeat without having to worry about hangups.
Then, having read the reviews for the BCD3, I bought one, based on my experience with Bryston amps and preamp. (Jim Thiel put me onto the Bryston 4B in 2003)
