Behringer Ultracurve Pro DEQ2496

I used a DEQ2496 for subwoofer duties for a long time, to very good effect. I'm not sure I would use it for main speakers. There are aftermarket modifications to improve the analog audio quality.

But depending on what you're trying to do, a miniDSP SHD Studio might be a much better choice.

I see thanks.... I think it will be like an help to streaming, but also to room correction... why dont you think not usable for speakers? 

I am using it right now as a dac for my pc & tv. This cheap thing is simply one of the best dacs out there. It sounds of full bodied music and not dryed out hifi like most testwinner dac`s do. The downside is it`s build-quality, the powersupply are known to suicide, most likely from heat so pay some for an extended guarantee. 

This unit adds no noise but the result out will depend on how many processes you decide to do or if you simply press "bypass". 

Only xlr out, if that`s a problem you can use these:
