mesch,
I have a BDA-1, and it is a fine DAC (I now have mine in my second system). I also have a Bryston BCD-1 CD player. Some years ago before I got into streaming, at the same time that I auditioned the BCD-1, I also auditioned the BDA-1. Both at the dealer and and with a borrowed BDA-1, I experimented with a number of lesser CD players and DVD players, including my own Denon 2910 DVD/SACD universal player hooked up to the BDA-1. It was no contest, even thought the BDA-1 was the technically superior DAC to the similar DAC built into the BCD-1, in terms of SQ, the BCD-1 just simply outperformed any of the combos I compared it to. I came into the shop thinking about buying a good DAC, but wound up buying the BCD-1 instead. When it came to spinning plain vanilla Redbook CD's the BCD-1 with it's rock solid Redbook CD only transport was the clear winner. So the transport really matters. A couple years later after Bluesound integrated streaming from Tidal I picked up both an original Bluesound Node and a BDA-1 to go with it. It was and still is a very good combo, but couldn't quite match the BCD-1. It was only after I started using a Melco N1A as my NAS (effectively as my CD transport) that I was able to approach the BCD-1 level of performance.
