DAC as preamp w/subwoofer

Thanks for the answers. I am using a Totem Storm subwoofer that has low level line inputs. The cable is 13 feet from preamp to the sub. The power amp (Rotel Rb 991) is right next to the preamp (Acurus RL11).

I am in the process of overhauling my system and thought this would be a good way to upgrade the preamp and my existing CD player (Arcam Alpha 8) at the same time.

I should clarify that the preamp has separate outputs that go directly to the power amp and to the subwoofer.

Al, Thanks so much for your comments. It sounds like there are a couple different ways to go at this. It sounds like I will have to do some experimenting to see what works best. In the worst case if I don't get it set up in a way that Works well I can stick with the preamp and upgrade thatat some point down the line.

Great ideas. I had not thought of trying to use the power amplifier. it sounds like I could pull this off. I am amazed at the willingness of all to help out. Thanks again.
