I agree with the goal of reducing background noise to allow your system to be at its best. I tried a DSP product last month but rejected it for several reasons. One, it significantly increased the noise floor hum. This might have been related to the fact that my preamp output voltage was over the recommended input limit of the DSP. I’m not blaming the DSP per se, just that it was not suitable for my system.
My goal of late is to minimize the ringing in the room in the low frequency range. I put this in the same category as noise because the music signal is fighting to be heard thru this unwanted sound overhang. To the extent I’m able to improve the decay time, the music becomes clearer. And it’s amazing how changing the location of a minor piece of furniture (basket full of magazines) alters the decay rate. I would not have believed it if I hadn’t seen the waterfall measurements.
