I haven't shopped for one of these in a while, but I had to go semi-expensive to get that feature. I ended up with a clearance Monster HTS 3000 unit. It has delayed on and off outlet banks that work like a charm. Turning on the receiver boots all preamp devices first and then boots the amps 10 seconds later. On power off, it delays the preamps from turning off for 6 seconds. No more thumps. I can set any bank to switched, on, or delay. It works well and was around $300 on clearance.

I had not seen that feature at a cheaper price point, but that was three years ago.
