Need Processor Input

Okay, I need some input. I have a Theta Casablanca I with standard dacs that has served me well. I run a Naim CDX CD player through the analog direct so reason the standard dacs have been good enough on movies for me. Unfortunately when I purchased my CBI, I didn't get the DTS board. Now with Blu-ray having so many titles with DTS, I'm wondering what to do. I could buy a used processor that does both dolby digital and DTS in lossy and save a lot of money and still have a good preamp for my CD player or buy an Integra for $2k which probably would force me to run a separate preamp proably for another $2k or slightly less if used.

I'm not wanting to get in a debate over lossless vs lossy but I read an article off the internet where a group of reviewers went to Dolby Digital Labs and DTS to hear sections of movies both in lossless and lossy in a controlled environment with expensive gear. Most could NOT hear any difference while a couple did but said it was very slight with lossless being a touch better. The improvement was described as being slightly fuller sound with slightly more surround information.

With this, I'm wondering if I should really get the Integra 9.9 that could do all the lossless but also have to buy a preamp or just buy a used processor for a fraction of the cost and still be pretty darn happy. I can tell with my CBI that the sound of blu-rays sound better than the same standard dvd copy but that could be due to a different sound mix. I just watched the Blu-ray movie of Nightmare Before Christmas in plain DD 5.1 and couldn't believe the improved surround sound and clarity of the songs in the movie. It sounded so good that I really wondered how much lossless or better dacs could really improve the overall sound. This was the big reason in the beginning for not spending so much on Theta's expensive upper end dacs and deciding the standard dacs would be pretty darn good for movies. As for movies and music, a couple of the biggest factors is the source recording and the listening environment besides the rest being the equipment.

Any thoughts from those that have gone from an older processor to something newer???
Robert I also have the Toshiba HDDVD player. I kept this because of the beautiful processing of regular DVD's. I would look into an OppO SE which gives you better up converting dvd and fabulous blue ray. I also have the Pioneer O5FD and like the Oppo better. I would think the Pioneer 09 is better but I have not compared the two. I am also using the Classe as an analog pass through and it sounds great. The nice thing about the Oppo is that you can set the individual levels of each speaker in the analog mode to a greater degree than I could with my Pioneer.
The SSP-600 is a great processor and sounds extremely good; it's 2-channel balanced bypass can take the place of a pre-amp for 2-channel listening if you don't have extra money to spend on the extra box. If you are using your player to decode the latest formats and routing them out the analog outputs, you can even get by with a 7.1 multi-channel pre-amp (there are few on the market from Parasound and other vendors) as well but you'll sacrifice video-switching and post-processing for DD and DTS 5.1, 6.1 'older' formats.
find the 5.1 input for your processor or get one with them.i run my blue ray thru the anolog outs to a nuforce avp17 anolog 7.1 inputs and with some room tweeking it sounds good with the dacs in the blueray . I just wish there were more 7.1 movies available. I did play one or two 7.1 movies with the new hd digital an hd dts and it is great..but most movies are in blueray 5.1 and its really no differ to me wether i use the coaxal out on blueray or the anolog outs..ive got some blue ray music and its great in hd 2 channel but it only feds 5.1 on most of them,
