Finally got around to setting this amp up in a 7.1 configuration, and am slightly un-impressed by the little difference, if any 7.1 makes over 5.1. I thought it would be better to spin a real DTS ES disc so watched blade II today, but... I selected 6.1 DTS ES in the sound options on the DVD menu, and there was no sound at all in the film, tried every setting on the amp to no avail, so had to use 5.1 setting. This still provides 'some' sound from the rears, but nothing noticable, and certainly not worth justifying the cost of the speakers!! My question is, why did the 6.1 ES settings not work, am i missing something? Is there a setting to adjust or something?
