I recently compared surround audio calibration results of the built-in Beosystem 3 tones against those supplied on the Avia calibration DVD.  The results for surround speakers are way different, with the Avia calibration resulting in surround speakers about 10 dB louder than from the BS3's built-in tones.  I'm tending to trust the Avia calibration.  Anyone have any thoughts on this?
