I was planning on buying a preamp with dts and dolby digital processing as well as stereo. I've read that preamps have a noticeable difference compared to receivers. My question is...has anyone tried comparing the sound when connecting 1) the 6 channel outputs on their DVD player to their receiver's 5.1 inputs and 2) connecting their DVD player to a separate preamp... Any other cost saving configurations? I'm looking to see if I need a preamp. I listen to both HT and Music equally... I guess this question boils down to whether preamp separates have better processing as opposed to the processing done in DVD players.
