KRK ERGO

Tholt what does the frequency response of your room look like;maybe just room treatments would solve any issues.

I haven't measured my room -- that would be the hard way. I was hoping the KRK would just do its thing. The room suffers primarily from a lot of reflective surfaces and open area creating slap echo. Addtionally I have vaulted ceilings that go to 12'. I've treated upper corners, rear wall (since my head is close to it), behind speakers. First reflection points, ceiling are likely next. I'm addressing the issue more seriously now that I'll be doing the work.

I am a very satisfied owner of the Ergo.

It only addresses/corrects up to 500Hz, so if brightness is your issue than you need to look elsewhere most likely although I suppose corrections in the lower frequencies could give the listener the impression of less brightness. The Ergo also asks for numerous specific microphone placements to take measurements. There should not be much experementation with mic positioning. (Although if your results were poor I can't blame you for trying)

In my room it worked very well. The bass became much more solid and imaging greatly improved since it does level matching. The fact that is is also a very good sounding DAC is the icing on the cake.

The Ergo asks for multiple mic placements after the focus position. It did not ask for specific mic placements -- in fact it specified to get very general with mic placements to emulate real world listening from a global standpoint. Different positions until it measures 90% understanding or above -- plug and play. But I can't believe that the room corrections it did were trying to compensate for any brightness. They were flat out BLOATED. My room is not atypical -- it's a living room, with the usual plants, couch, curtains, rugs, etc. There is some slap echo, but nothing out of the ordinary.

If you're also citing level mismatch between channels -- are you referring to db levels at the listening position? Not the case with me. My levels were matched.

As I said, perhaps my experience was an anomaly, though one I wasn't expecting. I'm saddened with the results and don't know what to attribute them to. No doubt that others have had better experiences, but mine have not been.
