David,
I'm just taking a guess here but if you're able to listen to music right now that Yamaha amp is probably an integrated, in which case you wouldn't need a preamp because you basically already have one. That's just a guess, am I right. All a preamp constitutes, is a volume control, a source selector, and some minor amplification and buffering. An integrated amp is a preamp and an amp combined. I hope that helps and I apologise if you already know this stuff. I'm just guessing due to the fact that you're a new member, have entry level components, and the way your phrased your question.
