The surround sound in "blockbusters" is simply brilliant - it bangs, trembles and buzzing around you as if you're right in the middle of the action there. Granted - the settings for the individual sound taste are limited - so absolute "sound freaks" then rather inappropriate. For me, the existing Klangmodis are very good and offer a - as I said for me - perfect sound. My attitude is basically Sound Effect "Natural Plus" (always 5.1 sound) and when it will bear the footage as 5.1 sound, the "3D Sound" button for this. But beware: "3D sound" is possibly displayed as 3.1 sound at inappropriate rehearsed material - then rather choose for 5.1 sound only "Natural Plus". Even radio, CD or music from USB are perfect in "Natural Plus" mode and the bass is orderly to the point. I had about the "Speaker Level" - can be set individually via each speaker - highly withdrawn the bass and I had the surround speakers more volume assign so that they come into their own - but is all a matter of attitude, from the location of the speaker dependent and individually different. Have the volume turned up so far only up to Level 20 - so only half of what's going on - and that was bearable, unfortunately for my neighbor is not a long time. Conclusion: Can a lot, brings out all the best sound hevor and optically top for me. What more could you ask for 299, - Euro (snatched the flash range) ?!
