My Weiss DAC has excellent DSP available if wanted which I find very useful in some instances. Typically I leave it all off, but I really like the ability to tailor the sound for different situations.
What are your opinions of DSP's for speakers
This seems to be a popular trend with many speaker brands. Some have internal amplification with DSP's and some have external implementations of it like Legacy. I have heard some good results with it being used but don't necessarily like the idea of everything being digitized for the sake of room/bass correction. Do you own or plan on buying a speaker like this, or have you heard any using it?
