Anyway, I love what the 8033C does for my F112. Some say it's even better in combination with the ARO.
While I'm sure the 8033 is a very nice equalizer, it can't help with the *first* step, which is subwoofer placement. You need the visualization of the response for that. If I were to get the 8033, I would want to also get some kind of measurement software to use for sub placement and for verification of the benefits of the EQ. The SMS-1 offers that visualization, plus many more tweaking and optimizing features, (phase control in 15 degree increments, subsonic filters, multiple presets for different listening programs, etc.) You can see as well as hear the effects of using all these controls.
The SMS-1 may not set EQ filters in the time domain, but all equalization has an effect in the time domain. A room mode, resonance or standing wave is a time domain issue and when you reduce the levels of the resonances, they fade out faster in the time domain.
marky301067, does your receiver or pre/pro have Audyssey? If so, what version of Audyssey?
