I'm looking for suggestions on picking up a new (to me) pre-amp and amp, or an integrated receiver. My current setup is a JVC RX-888 powering a pair of Klipsch KG4. After doing some research, I realized that to really hear these speakers I need a something a little better and so started looking for a more dedicated amp and preamp system. I've been checking out craigslist for deals on vintage stuff and just recently passed up a deal on Onkyo Integra Pre-Amp P-304 and Amplifier M-504 for $375 - kinda kicking myself for that one. There are plenty of used Sansui and NAD in my area, but at this point I need to decide whether or not I am looking to get separates or an integrated receiver. I am not concerned about upgrading to a multi-speaker system or adding a subwoofer, as these speakers take up a lot of space and make plenty of terrific sound.

Please help me pick out a new system. The only limit I have is funds - $700 limit. Thanks!
