I feed my AKSA with a Yamaha HT receiver, off the pre-outs. Not much to it, just plug the preouts for the Front left and front right into the AKSA inputs, and connect these speakers to the AKSA, instead of receiver.
Chances are the gain from the AKSA will differ a good bit from the receiver, so you'll have to recalibrate the sound levels to get the same SPL though all 5,6,or 7 speakers.
Doing it this way will involve the AKSA 100% of the time, whether watching a movie, or listening to a DVD. The only thing "wrong" with it is the preamp in an HT receiver is not going the be the best in the world. However it will work well - and improve the sonics from all sources.
At some point you could consider adding a passive preamp. For example, Channel Islands makes a relatively inexpensive one with a switch for 2 inputs (one could be a CD player, the other - the HT receiver). Or you could DIY a similar passive out of a top notch DACT attenuator. Either would likely be a noticeable step up. Then if you would like to climb all the way up the steps, the solution is to build a GK-1M or GK-1R, which quite nicely integrates into a HT setup.
