The Surround Master is as close to all in one as you can find. It will do SQ and QS/RM(and almost EV4). The only devices with CD4 built in are ridiculously rare and expensive, only for the UK market and do a poor job of any of the formats. I hope I am wrong but I think the current possible CD4 demogitator from Chucky et all won't have the other two included. If it is and I am wrong, that will be your only realistic choice. Save up now and follow Chucky's posts for further news. That is what I am holding out for, and I already have legacy individual decoders and demogitators. I like the vintage stuff, but if you care about your wife or your budget, you will await the new device that will save you money, space, headaches and your wife. Just look at the walls of sound in other QQ's posts and ask your wife if she is okay with all that and then decide! BTW, if the new demogitator from Chucky comes through and does not include SQ and QS/involve, you are still only in for two devices and a really small footprint as opposed to all the decoders and wires and switch boxes that some of us have, or be stranded in only one or two formats if you are forced to make choices.
