The sound is exactly the same to the T as a BDP-2
The sound card in both units is the same it's the Julia sound card
The only difference between the BDP-1 & BDP-2 is its capacity to play a much larger music library and of course the speed to able to change between units.
I will only upgrade my BDP-1 once Technology will bypass the Julia high-end sound card that Bryston is currently using.
I'm told the Julia is a very High end sound Card. So it looks like 3-5 years down the road.... Bryston will up Grade to a BDP-3
With a New Sound card with all the bells & whistles
So bottom line. The BDP-1 & BDA-2 Combo is the only way to Go
If you do have a BDA-1 change.it sell it ... You will not regret it..
The BDA-2 will put a smile on your loved ones !

Hi Robert
I got the BDP-1 ,I am curious, do you happen to know, how large of a music library (Gb) the BDP-1 can handle compared to the BDP-2 ? Also what do you mean "change between units"?
Thanks
George
