I believe this is relative to the BDP-1, the power supply was left identical (specs) to the BDP-2 to allow older units to be upgraded.
Since BDP-1 is no longer produced, the blurb on Bryston's site should really read,
power supply delivering over 5 amps"
Loud and clear there, and not misleading.
Q: Why does a digital player with no analog output need 5 amps??
