Thanks for sharing your experience Dr.House.

So that makes me zero down on XPA 3. This provides me with sufficient SPL (around 110dB in stereo) and also a headroom of around 4dB over and above 110db (considering room gain). This headroom will make sure that the amp does not go in clipping even at such high volume.

Thanks for the help guys.
