I have an Angstrom 100 processor, designed by Mike Moffet. It has no video inputs or DTS. Sounds pretty good to me and built like a tank. I also have 2 Citation 7.1 amps, two 7.4 subwoofers, Sony SS-9 speakers, (great sound and bass,) Aerial CC-5 center channel and Citation 7.3 surround speakers. My Sony RPT has 5 video inputs that are easy to switch to. Also I have a separate high end system to listen to records, CDs and 96/24 DVDs so I am primarily interested in a processor for home theater. Obviously 5.1 inputs would be nice to listen to multi-channel music but not essential. Would like to save up money to purchase a HDTV and not spend it on an expensive processor. I just returned an ADA Rhapsody processor (See ADA thread.) Now I'm wondering do I really need to upgrade and would like your comments in an effort to provoke some discussion on these issues. I will number them to make it easier for you to respond to. Thank you for your input. 1. Do I really need DTS. What percentage of software is issued in this format? 2. Do I really need DPL II? This would seem very nice as it passes all of the signal not just the high end. also the matrixing is better. Is there much of a difference from the original DPL? 3. Do I really need DD Surround -EX, DTS-ES, DTS Neo-6 etc., etc? My understanding is that these only work when there is a flag in the signal. 4. Thinking of buying Parasound CSE 6.1 Center surround Expander. Works with all modes. Also can hook up subwoofer to surround speakers as it has a crossover. Also has ceiling outputs for two more speakers. All for $400. 5. Maybe sell my processor and buy a good used processor like the Citation or something else with DD and DTS and the Parasound unit. 6. Throw in the towel and buy an Outlaw 950 processor. This has a mode similar to the Parasound that I believe works with everything. If I go this route can I use one of the rear channels with a speaker in the center of the rear wall and the other for a ceiling speaker. As the matrix signal is mono, wouldn't this work? Also is there an inexpensive crossover to hook up one of my subs with the surround speakers?
