My HT setup was calibrated using Audyssey Eq. I have tried all the Eq settings (Reference, Flat, Bypass L/R). This past few days when watching music concerts it sounded a bit too sharp to the ear especially when playing very loud. This evening I decided to check the Audyssey Eq and realised that it was on Flat. I put it back to Reference and all that brightness was gone. It was so much easier to the ear again. Those that use Audyssey what?s your preference and experience of the different settings
