options for 2.1 sound


I have a 2.1 channel system with bookshelf speakers, a pre amplifier and a 2 channel power amplifier and a subwoofer. Currently I have an adcom gtp-600 surround pre amp but I'm not satisfied with it (I'm actually quite confident that it's damaged in some way.) I want to get a new pre amp and am wondering what the best solution is. I know that I can get a normal 2 channel unit and run the speaker cables through the sub but I'm hesitant about this because I don’t want to tarnish the power going to the speakers by sending it through the sub. I could opt for another 5.1 channel unit (outlaw audio 950?) but then I'm paying for capacity that I won't use, and likely getting lower quality 2 channel sound than I would with a stereo pre amp. I also have been told that I might be able to employ a 2 channel pre amp that has multiple outputs (Adcom GFP-565?) and send one to the sub and one to the power amp. I’m thinking this may be the best option. Any advice/ help would be greatly appreciated.

Check out the B&K PT-3. It is a 2.1 remote controlled preamp, inexpensive on the used market and sounds very good! Has full range, high pass, and subwoofer outputs. Much better sounding than the Adcom.
hi bill,you wouldnt affect the power going to the speakers by running them from the sub,the sub will only take a sample of the signal then send the power to the speakers.

if your worried about adding something to the signal path by running the speakers piggy back off the sub & coloring the signal in some way then i see your point but it wont affect wattage/power in any way.

you are correct about being able to use a 2 channel pre with multiple outputs in such a fashion,are your buying preferences new or used & what budget.
