I currently have an ICBM hooked up as
DVD->ICBM->Pre->Amp

what would the advantage be to hooking it up as:
DVD->Pre->ICBM->Amp

as I see some of you are doing here.

BTW, I am using an Onkyo 898 AVR as my pre and a Sherbourn 5/1500A (200x5) amp, along with a Panny RP91 DVD-A player, a single sub, Rocket speakers.

If I do this, I will set my speakers to large on the Onk, with sub set to yes.

Any risk involved here, any advantage here?

TIA
