A proper bass-management system would have you set crossover points for every satellite, crossing each satellite to the sub with a highpass for the sattelite in question, and the signal highpasses from the sattelite in question then lowpassed to the sub, individually for every channel, with a separate crossover setting for the LFE channel lowpass.
Sherbourn PT-7030 does only 1/2 of this. If you set the Left channel crossover for 80Hz, and the SW crossover for 200Hz, the sub plays far too high. The Sherbourn cannot tell the difference between LFE signal and bass-managed signal. The way the crossovers are set up, the satellite crossovers are simply 'highpass corners' and the SW crossover is a 'lowpass corner', with no available setting for the LFE-only signal. If you have Large LCRS, and set the LCRS at 40Hz, but the SW at 80Hz, too much energy goes into the sub. If you then set the Sub to 40Hz to match the LCRS, you lose out on all the LFE content above 40Hz (LFE channel has significant content often to as high as 200Hz).
Because the nanoAVR can do bass management and do the parametric EQ that the Sherbourn cannot do with its significant limitations, and the fact that the Sherbourn cannot handle a high strength 7.1 LF signal without destroying the waveform, I use the nanoAVR to not only decrease the overall level to something it can handle, and do everything it cannot. The Sherbourn has one great thing going for it, and it is important. It has a VERY low noise floor. If you can get past the HDMI and other issues, it is the quietest processor I have encountered.
