Larry, I haven't come across any integrated amp that offers bass management. The Outlaw offers a very simple and convenient way to hook up a sub in a two channel set up. As for the tuner, I don't think I even know where the little antenna wire is for my HK. Like you, I never use it.

Here's a link showing ways of hooking a sub up to different systems.

I like the retro look to the RR2150.
