I have been thinking about how nice it would be to have have a good sounding DSP for crossover and delay functionality. I know this subject was covered here before but what was talked about is this DSP is not that good, and this DSP is horrible, etc.. 
But, if it is possible to have a good DAC, why is not possible to have good sounding DSP? The dsp is adc + digital processor + dac, right? So if we apply proper signal level and there is enough processor power, would it not be possible to have good sounding DSP?

Romy has covered this a couple of times. It basically amounts to DSP can delay, but it can't transparently filter. Analog can filter, but it can't delay.

That being said, a DSP is a great tool to test crossover strategies and to help pick good ranges for getting different drivers cooperative. It can even be useful for those that do not demand the most advanced playback. At that point, it just doesn't belong at this site. There are other sites that can really appreciate the "technology".

I used DSP for a long time as I could not decide on how to crossover my horns. When I finally switched to a capacitor and time alignment instead of DSP, a bunch of other stuff became apparent...........
