I have a BCD-1 and a BCD-3. The BCD-3 is a noticeable improvement over the BCD-1 with more detail. Plus, the BCD-1 seems to have a high failure rate with the disc drive, which cannnot be replaced. If your disc drive dies, you've got a brick. The disc drive in my BCD-1 skips once in a blue moon, so I'm glad I have the BCD-3. With the BCD-1 connected to my BDA-3.14 with an AES-EBU cable, is it's hard to tell the difference between the two players, but without the help of an external DAC, the difference is easy to spot. If you do get the BCD-3, be careful when placing a CD in the tray. It's thin so it's easy for it not to sit properly. And hang on to the remote that came with your BCD-1. It's much better than the remote included with the BCD-3.
