Processor only - No preamp?

Here's a twist on several of the questions and answers I have seen here lately. I have a Cello music system (two channel) that I am thrilled with. Instead of using a (Cello) preamp, I use a Cello Etude which is a passive attenuator. The Etude blows away every (active) preamp I have compared it to (short of the Cello Pallette), and I am content with the system as is. Additionally I own an old M&K satellite & subwoofer system, and a couple of 200 watt amps. that are collecting dust. Here is the fun part: I would like to pick up an inexpensive DVD player ($300 - $400) to watch movies and be able to listen to the sound tracks in 5.1 audio. This therefore means that a 5.1 decoder is required. With all of the uncertainty surrounding the DVD format issue, I don't feel it's wise to spend a large sum of money on a killer cd/DVD player/transport with all the bells and whistles since no one knows which format will eventually come out the winner, and to put thousands into a good pre-amp for DVD (movies only) looks to be a waste. A local dealer has suggested a Marantz DPH-70, which is a "processor only", not a pre-amp. The unit is re-conditioned from the factory, does NOT have DTS, but will only cost me $360.00! This sounds like the way to go; my stereo system remains untouched, and the only other pieces of equipment I need are the DVD player and a center speaker. WHAT DO YOU GUYS THINK OF THIS? Any feedback would be very much appreciated. - Ken
