Best Complete HomeTheater USED for $5000.00

>>-What speakers would I need to add / if any?(Sub-center- Rears)<<

I would definitely recommend a sub-woofer for movies. If you're going to use
the sub-woofer only for movies, you can get a home theater type sub that will
rattle and thump for you and it shouldn't cost a bundle. If you want a sub-
woofer for music, one that will blend with your Caravelles, you'll want to
spend more and get one that is musical. If you go with 4.1 as I suggest,
you'll also need two rear channels. These will not be doing all that much and
home theater is not as demanding of quality gear as music, so you could get
by with inexpensive rear channels. Try to demo them in home to make sure
they blend with your front left and right channels.

>>-How would I connect the AV to my Jadis integrated??<<

One way would be to connect your Jadis to a two channel pass through in
your home theater processor.

You'll probably want to either add SDI to your Theta or update your DVD
player to one that employs DVI/HDMI. If you mod your Theta with SDI, you'll
be able to use an external scaler, which will give you high quality video and
you can run other things like cable TV through the scaler, too.

Theta still lists the David in its museum.

They offered an SDI option at one time ---

Further options include: 4:2:2 Serial Digital Video Out

I don't know if Theta would mod the unit with SDI at this time or if you'd have to take your unit to someone else -- several people do SDI mods. This is something you'd have to research. See who will mod your Theta David, how much the various people charge, and who has the most elegant solution.

This would allow you to keep using the David as your digital transport for CD's and DVD's.

Here is a company that offers SDI mods, but doesn't specify Theta David as a unit they mod. They charge $375 for the mod. That might give you some
ballpark idea of what it would cost for the mod.

If you add SDI and an external scaler, you're talking about spending
somewhere around $1,500. On the other hand, if you are not married to the
Theta David, you could probably sell it for around $1,200 and replace it with
something like the Denon 3910, which costs around $1,200 (stock). The
Denon 3910 is a universal player and has HDMI, which will also pass the
video signal in digital, saving you a digital to analog conversion, giving you
high quality video. It will also output SACD and DVD-A via Firewire.

Since you could probably sell your Theta for around the same price as the
Denon 3910, it would be a wash and that would conserve your budget for
other things. (You may want to mod the Denon -- I have heard great things
about the APL mods!)

Here is a projector you should put on your list --
