>>As well, do both the BDA and BCD exude the same characteristic sonics that Bryston amplifiers - i.e. SST/2 display - clarity, detail, punch, soundstaging, yet very smooth. I haven't had time to sit down with either to assess them.<<
I had both the BCD-1 and BDA-1. They have essentially the same sonic characteristic. The BDA-1 sound however is more influenced by the source whether it be computer or standalone player. Also the BDA-1 having two chips, one for each channel had better stereo seperation, and slightly more bass output.
