I ran audyssey with a mic stand and am happy with the sound but read that all prior forms of audyssey except XT32 heavily correct the upper frequencies over 500hz which can effect speaker performance and hardly correct the sub. I checked the eq corrections under the audyssey menu and saw that the upper frequencies over 500hz are in fact boosted 3-4 dB.
My question is, since I don't have XT32 in this receiver, am I better served with turning the eq off and using the anti mode for sub eq, using the audyssey eq, or using anti mode and copying the audyssey flat curve to the manual eq and changing all corrections for frequencies over 500hz to 0.
Regardless what I do, I am still using the levels and distances set by audyssey.
My speakers are the B&W 685 for front, B&W HTM61 center, PSB S5 for surround, and Tannoy Di5DC for front height. My sub is the HSU STF2. All speakers are crossed away 80hz except the Tannoy which are crossed at 90hz.
It is true that Audyssey flavors below XT32 work in a different way to XT32, which is more benign in the way it corrects the upper frequencies and concentrates most of its effort on the lower frequencies where correction is usually very much needed.
However, as you already have the AntiMode, which is a good tool for fixing LF room issues, why not just try both and see which you prefer? If you have already done the Audyssey calibration, simply turn Audyssey off and insert the AntiMode, run an AntiMode cal and see which result you find most pleasing, to your ears in your room?
Unless you have independent measuring gear, such as REW and a calibrated mic, there isn't much more you can do besides a listening test, so just give it a go. When comparing the two, make sure the volume control remains untouched between listening evaluations, and use content that has good bass and which you are familiar with. Pay attention to how tight the bass is, how controlled it seems, how deep it goes. Also pay attention to the higher frequencies and see if one evaluation sounds smoother or more pleasing than the other. Please let us know how you get on if you try this.
