I have the BDP-1 as well and just purchase the Ayre Codex about 3 weeks ago to replace my BDA-1 and it's definitely an improvement all around more detailed, soundstages more open and imaging is more pin point. Also works very well with my new Focal Elear headphones. Plus the fact that you are now bypassing the soundcard in the BDP-1 which also improves the sound quality of both units.
The only complaint I have is the Codex required approximately 500 hours break in.
