Yeah it will work temporarily or permanently for that matter. But your system will sound markedly better when you get a bonafide preamp for music (unless you have one helluva an AV receiver). Use the receiver for a while, so you can really take your time and get the preamp that you will be really happy with for a long while. It's murder trying to get your money back from experiments. With your nice speakers and poweramp, you're going to want to get a quality pre to match.
Good luck.
