    Well it looks as if my new Sunfire Theater Grand II will be going back and I need to fill the void. A pre-owned DC-1 may fit the bill. Here are the questions:
    1. Is there speaker setting memory for each speaker mode? For Example, if I turn off the sub for stereo will it still be on for DD and DTS?
    2. THE DIN connector: I'm assuming that I can use this to trigger my amp? Can I get the cable at any Radio Shack?
    3. Full on-screen menus?
    4. Anything else?
    I guess that's it for now.

    1. There are two places where you can turn the sub, side surrounds, and rear surrounds off or adjust the volume: in the setup menu, and in the mode parameters. Mode parameters are stored on a per-mode basis where things like AC-3 Logic 7 and DTS Logic 7 are different modes.
    IOW, you can have the sub off in 2-channel, music surround, etc; and on in all other modes. Or off in PCM modes and used only for LFE in AC-3/DTS.
    Note, however that you only get full configurability in the setup menu - it's the only place you can change cross-over frequencies and volume/time delay for each individual speaker.
    2. The DIN connector has two triggers, one which comes on when the preamp is turned on and the other which is programable on a per-mode basis (you could use this to turn on additional amplifiers for surround modes or whatever). Any good electronic shop will have the mini-DIN connector you need and the 1/8 plugs other components have; although I don't know if Radio Shack qualifies as "good."
    3. Yup.
    4.1. There are four flavors of DC-1: base, THX, AC-3, and DTS with each including functionality of the lower model. If you look a bit, you should be able to get a DC-1 DTS with the latest v4 software for under $1500. Upgrading to v4 is $300. Upgrading AC-3 to DTS with v4 is $500. Either upgrade will require a $75 surface mount chip swap at the factory for units with serial number 5125 or lower. Going from a base or THX DC-1 to DTS is $1500 so buying such a unit is not worthwhile.
    4.2. Logic-7 with 7.1 speakers is unequaled except by Logic-7 in other Lexicon processors. You _really_ want to upgrade to two pairs of surrounds if you haven't already.
