OK, I'm ready to pull the trigger for my first A/V receiver. I've spent quite a bit of time researching and reading posts (muy informative, BTW) and I'm down to these last three from JandR.com (I've bought from them before and trust them). The three are: Sherwood RD6108 Panasonic SA-HE75S Yamaha HTR-5540 I don't have the money to get a higher-model receiver such as the SA-HE100, so don't suggest other models, please. BTW, I'm using Jensen JHT-525 5.1 speakers if that matters. Any advice regarding the best choice would be most appreciated. Thanks!
