Hi, I've been reading a few comments from some of you on the Panasonic, Harmon Kardon, Denon, Sony...etc home theatre receivers. I appreciate the comments. I'm looking to change my 5.1 home theatre (Sony) set up to a 7.1. I also want to change the speakers from standing speakers (JBL - front), (Boze 401's) on the back to Satellites. Do you have any idea if any of the units (receiver/amps)have more "brilliance" (treble)? (Preferably around $500 or less.) I am a little hard of hearing in the upper range and the way I compensated in the past was to buy additional tweeters and set them on top of the speakers (Radio Shack sold an add on stand up tweeter.) I have also heard that out of the satellite systems available,Infinity (Tss 450, 750 or Modulus) has about the most treble or brilliant upper range. (Compared with Klipsch, Polk Audio, JBL, etc...) Again, I am not looking for a "flat" response as many audiophiles recommend. I am looking for a lot of treble at a low volume with the speakers and amplifier. Thank you!
