A good CD transport should load fast and be very mechanically silent. I had an old Sony ES CD player years ago that I used as a transport. It would only play redbook CDs, and it loaded faster, switched tracks faster, and ran more silently than any multi-disc reading transport I've had since.
New, Very Interesting CD Transport
On John Darko's website today we learn of the brand new Shanling ET3 CD Transport. And for $729 USD it looks really capable. Top loading with Philips SAA7824 drive. AES/EBU, coaxial, TOSLINK and I2S digital outputs. Plus Wifi and Bluetooth. USB to connect to a external HD and built in upsampling, too. It even will output digital to USB for connection to a DAC but not with upsampling.
Here's the skinny:
