<font color='#000000'>The bass management on your receiver won't make any difference one way or the other, when your source is either SACD or DVD-A. For SACD and DVD-A, you will be connecting the player to the receiver through the 5.1 analogue connections. You will set the bass management in your new 2900 or 5900 and pass it on, already bass managed, to the receiver. So, hang on to your receiver. It's still fine.
For Dolby Digital or DTS, you can use a digital connection, i.e., a coaxial or an optical connection.</font>
