I currently have my speakers calibrated and placed pretty well for HT - specifically for Dolby Digital 5.1. The fronts also image pretty well for 2 channel stereo. I will be connecting a DVD-A player shortly and I was wondering if the speaker placement will necessarily be the same? Recalibrating them for a new source is simple, but moving them each time I switch sources is not possible. In short, is the 5.1 speaker placment for DD 5.1 the same as the 5.1 speaker placement for DVD-A? BTW, my setup is the Divas 4.1/2.1/c3 with a HK avr520. The new DVD-A unit is the JVC XV-SA70BK. Thanks.
