It doesn't do any good if you wanna upmix stereo to 7.1, it adds nothing just blends stereo channels to rear, side and middle but if you leave it at stereo the HRIR still gives more advantage than unaltered stereo.

That's what I don't get. It has option to upmix+downmix for exactly this scenario. But how is a HRTF supposed to do any better than originally stereo? Left is left and right is right.

But now you have HRTF delay that makes the sounds appear more accurate.
Without HRTF the sound would hit only the left ear but with HRTF the sound hits the right ear with a slight delay and it makes the "range and location finding" faster and more accurate.

But HRTF doesn't know it's needs to add delay (since it doesn't have position info). It just just knows that this sound source has a 50% level on the RT and 10% on the LT. I suppose may be it always assumes to add a delay when this happens?
